What could your life look like?

Your time is now. Every day you wait is time you don’t get back -a day spent tired, foggy, disconnected from your own life. Autoimmune diseases drain your energy, your focus, your confidence. Waiting feels safe, but the real risk is letting months or years slip by in survival mode. The sooner you start, the sooner your body can begin to shift so you can feel better. It’s time to reclaim the life you want to live, with the clarity and capacity to show up fully at work, at home, and for yourself.

What life looks like now:

You feel tired all the time, even after a full night’s sleep.
You’re living in constant survival mode -just getting through the day feels like a win.
Your symptoms seem to have a mind of their own -unpredictable, frustrating, and hard to explain.
You’ve tried countless diets, supplements, and specialists with little lasting change.
You cancel plans or miss out because your body just can’t keep up.
You feel disconnected from your body, like it’s fighting against you.
You rely on caffeine, sugar, or willpower to get through the day.
You worry about your future and whether things will ever get better.

What life could look like:

You wake up refreshed and energized -your body finally knows how to rest and restore.
You move through your days with calm focus and steady energy, no longer ruled by fatigue.
You understand your body’s signals and know how to keep it balanced and resilient.
You’ve found a way of eating and living that truly supports you.
You have the energy and confidence to say “yes” to the things -and people -that light you up.
You feel a sense of partnership with your body -learning to listen, respond, and trust it again.
Your energy feels steady, sustained, and natural -no more afternoon crashes or quick fixes.
You feel hopeful, empowered, and clear on the steps that truly support your health.

There are over 100 different autoimmune diseases that have been identified. A few include:

Addison's disease is an autoimmune condition in which your adrenal glands don't produce enough of the hormones cortisol and aldosterone.

Celiac disease is an autoimmune disease in which gluten proteins trigger an immune response that damages the small intestine.

Crohn’s is a type of inflammatory bowel disease (IBD) that causes swelling and irritation in the digestive tract.

Graves’ disease is when the immune system creates thyroid antibodies that activate thyroid-stimulating hormone receptor (TSHR), producing hyperthyroidism.

Hashimoto’s occurs when the immune system makes antibodies that attack the thyroid gland, resulting in decreased production of thyroid hormones, and hypothyroidism.

Lupus (Systemic Lupus Erythematosus) is an autoimmune disease that causes severe and persistent inflammation that leads to tissue damage in multiple organs.

Multiple Sclerosis (MS), is when the immune system attacks proteins located in the insulating myelin sheath of neurons, resulting in demyelination and neuronal death.

Psoriasis is an autoimmune disease characterized by patches of red, pink, or purple, dry, itchy, and scaly skin.

Psoriatic Arthritis is a chronic inflammatory arthritis that causes joint pain, stiffness and swelling.

Rheumatoid Arthritis (RA) is a chronic inflammatory disorder that causes severe swelling and pain in joints.

Sjögren’s Syndrome attacks the lacrimal and salivary glands, resulting in insufficient production of tears and saliva.

Type 1 Diabetes occurs when the immune system attacks and destroys beta-cells of the pancreas, resulting in insufficient insulin production.

Ulcerative Colitis is an inflammatory bowel disease that causes irritation, inflammation, and ulcers in the lining of the large intestine.

What is autoimmunity?

Autoimmune diseases like Hashimoto’s, Multiple Sclerosis, Psoriasis, Crohn’s and Rheumatoid Arthritis are defined by conditions in which your immune system mistakenly turns against itself. Your immune system usually protects you from diseases and infections, but in individuals with autoimmune diseases, the immune system loses self-tolerance and is no longer able to differentiate between its own cells and foreign invaders, causing it to attack healthy cells, tissues, and organs (1). Autoimmune conditions are marked by common factors: an overactive, chronically alert immune system and widespread inflammation.

Autoimmune conditions can impact all systems in the body. They are chronic, painful, and can be life-threatening. In the US, autoimmune disease is the third most common type of illness after heart disease and cancer, affecting nearly one in five Americans. An estimated 50 million currently have autoimmunity and of the millions diagnosed with autoimmune disease, nearly 80% are women (2). Autoimmunity tends to affect women during periods of extensive stress, and during great hormonal changes such as pregnancy, perimenopause and menopause (3).

The statistics on autoimmunity are daunting:

In the past 10 years, some autoimmune diseases have increased by nearly 300%.

Type 1 diabetes prevalence has nearly doubled in the past 40 years.

Inflammatory bowel disease increased by 46% between 2006 and 2021.

Celiac disease has increased five-fold over the past 30 years, doubling every 15 years.

It takes, on average 4.5 years and 4 doctors before a correct autoimmune diagnosis.

Predictive antibodies can be detected up to 19 years before clinical disease.

Your body is designed to heal.

The current medical system, which is well able to handle acute care situations, does not always know how to assess or treat chronic conditions like autoimmunity. In fact, surveys show that most physicians report that their training in chronic disease is less than adequate (4). Conventional medicine has pharmaceutical options for the treatment of autoimmunity, however many people don’t feel better because the underlying immune dysfunction that created the disease hasn’t been addressed.

If you’ve been diagnosed with an autoimmune disease, you may be feeling frustrated and overwhelmed. While genetics may increase the risk of autoimmunity, environmental and lifestyle factors play a larger role in these conditions. Once the underlying root causes are addressed, our clients’ symptoms resolve and they feel better. This improved quality of life might be increased energy, sleeping through the night, losing weight, or finally getting rid of the brain fog. Your body is designed to heal.

From surviving to thriving: A new approach to autoimmune conditions

What makes Britesquare’s approach different and more effective? Here’s a side-by-side look at two very different ways to address autoimmunity, and see how a new model of care offers better results and long-term relief.

Managing symptoms:

15-minute doctor visits, or one-off consultations.
Focus on managing or suppressing symptoms.
One-size-fits-all medication.
Not addressing the underlying immune dysregulation
Dismissal of "non-severe" symptoms.
Reactive care.

Creating lasting change:

Ongoing, personalized support and coaching.
Focus on addressing root causes and system balance.
Customized protocols based on your body and labs.
Balance the overactive immune system.
Every symptom is a clue and opportunity.
Proactive, transformational journey to reclaim energy and vitality.

Britesquare’s Autoimmune Transformation Program

This program is created for women with autoimmune conditions who are ready to move beyond guesswork and finally understand what their body needs to heal. We believe autoimmunity isn’t only about managing symptoms -it’s about identifying and addressing the underlying imbalances driving them. Many women with autoimmune conditions have already tried diets, generic protocols, or prescriptions that only skim the surface. Britesquare takes a deeper approach, combining advanced functional lab testing with a proven four-part framework to uncover and address the powerful connection between nutrition, gut health, mindset, toxins, and immune regulation. This program fills the gap where others have fallen short -guiding you toward real and lasting change.

Britesquare’s Autoimmune Transformation program is a high-touch, personalized 1:1 coaching experience that builds nutrition and supplement protocols from your unique lab data, including cutting-edge tests such as the DUTCH, GI-MAP, and Alletess food sensitivity test. We carefully monitor your progress, adjust as needed, and support you in creating sustainable habits that build long-term resilience. By calming the immune system, reducing chronic inflammation, and nourishing the body as a whole, transformation happens -not only in your labs, but also in your energy, clarity, and confidence. This is your new way forward -and it works.

Our comprehensive four-part framework explores the many factors that affect autoimmunity.

Diet & Nutrients

We know our immune system responds to the foods we eat, this is proven by research that shows that a nutrient-dense diet is one of the most powerful treatments for autoimmune disease. Consuming fewer inflammatory foods, adding immune-supporting nutrients, and removing food sensitivities will help build a stronger, more resilient body and balanced immune response.

Gut Microbiome & Leaky Gut

We believe that addressing gut health is a crucial part of any autoimmune program. Mounting evidence shows that poor gut health is a feature in virtually all autoimmune conditions, and that by balancing the microbiome, healing leaky gut, and addressing chronic gut infections like H. Pylori and parasites, we can prevent, and even reverse, autoimmune conditions.

Environmental & Dietary Toxicities

We are all overexposed to chemicals. Environmental toxins are significant risk factors in the development of autoimmune disease. They impair the immune system, disrupt detoxification, promote inflammation and damage mitochondria and gut bacteria. By detoxifying our body, diet, skincare products and living space we can optimize our body's detoxification system and balance the immune system.

Mindset & Lifestyle

We consider the mental and emotional elements of the individual as integral to immune health. The connection between stress and immune function has been documented for over a century and is an established risk factor for autoimmune disease. By improving mindset, and prioritizing sleep, movement, and stress management, our autoimmune clients go from surviving to thriving.

You’re not willing to invest in yourself or your health. If you're not prepared to dedicate time, energy, and financial resources to your healing, this program won’t serve you.
You’re skeptical of a functional, root-cause approach. If you’re not open to exploring this path, results will be limited.
You’re resistant to making real lifestyle or mindset changes.
You expect someone else to “fix” you without personal effort. If you’re not ready to take ownership of your process, this work won’t stick.
You want a one-size-fits-all protocol, not a customized, adaptive process that evolves as you do.

If you're ready to feel like yourself again -we’re here to walk that journey with you.

Our client feedback demonstrates our commitment to you.

I am beyond grateful for meeting Kim. Her exceptional support and guidance are the reason I have reversed Hashimoto’s autoimmune disease, it is possible! I no longer have joint pain, muscle aches, migraines or brain fog. My anxiety has decreased and my digestion and mental clarity have improved. I am calmer and sleep better. When I first met Kim, I was overwhelmed and facing a series of health concerns. Her intuitive sense and compassionate approach immediately put me at ease. Kim’s passion for learning directly benefits all of her clients. She is incredibly knowledgeable about the most current research and can solve so many complex puzzle pieces to achieve optimum health. She is beyond dedicated to her clients, and it made a significant difference in my healing journey.
L.A.
We loved working with Kim and are so thankful our paths crossed! Our 14 year old son had a significant health issue. We had gone to several physicians and nutritionists to try and solve it. His gut needed to be healed and it required a lot of work. I was overwhelmed and scared honestly to do what I knew in my heart we must do to begin his path of healing. Kim guided us in a patient and thorough way through the entire process. She thoughtfully considered all the elements. We followed her plan to a tee and honestly it was easier than we thought. He went from struggling to gain weight across an entire year to gaining 14 lbs in 5 weeks without adding any extra calories and has continued to progress. Thank you for helping our son heal after years of wasted time. We are finally on the right path.
J.R.
Most recently I worked with Kim after being diagnosed with Eosinophilic Esophagitis and Hashimoto’s Hypothyroidism within an 18-month span. My symptoms were severe. Kim helped me put my Hashimoto’s into remission and completely eliminate my thyroid antibodies. My inflammation has been reduced to the point that I no longer need to take the strong immune-suppressing medication that I have been reliant on the last four years. I feel so much better day to day, and confident in the knowledge that I am continuing to take the right steps to decrease my risk of chronic disease. Thank you Kim, I’m so grateful for your guidance and support!
J.L.N
I’m diagnosed with autoimmune ulcerative colitis. When I first started working with Kim I was having 5-8 loose stool movements a day. This interfered with my daily activities and quality of life because of the urgency to use the bathroom. I was worried that I’d eventually have my colon removed or be put on additional medications. I also recently had a severe flare that resulted in an ER episode and a 10-day course of steroids. Now, after Kim’s protocol, I’ve been having 2 well-formed bowel movements per day without urgency. I feel the best I’ve felt in a long time!
S.S.
Kim has changed my life. The lifestyle changes she has coached me through have clicked and I have not looked back. Specifically, going through an elimination diet with Kim was not as scary as I had initially thought it would be. Supplements, dietary changes and new daily practices can be intimidating and overwhelming. Kim hand-held me through the entire process. I not only feel my best, but realize what it truly means to live a healthy lifestyle. Kim is all-encompassing. She is attentive, available and a very good listener. Her passion bleeds out of her and that becomes contagious! She is the most even-minded, non-judgmental, trust-worthy and lovely person. My time with Kim has helped not only myself, but my entire family and for that I am forever grateful!
A.S.
Kim is my lifeline in this chaotic world. I never thought I, or my family, needed a nutritionist, but once working with Kim I learned so much about how best to support my family’s needs. What I love most is that Kim is not judgmental in any way. And she never offers advice that seems unreasonable- it’s all about how much or how little the client is willing to do. In particular, I am learning how food and diet can affect kids with attention-deficit issues. I’ve already witnessed behavioral changes when providing my kids with the proper nutrients.
A.M.
Kim is extremely knowledgeable, tremendously passionate & genuinely caring. She is a fellow mom who totally gets it. Kim has shared her expertise in helping me find new ways to help my son who has ADHD: Through her loving guidance and support, I have learned how nutrition and supplements play a vital role in one’s ability to focus and concentrate. She has also helped our family with staying well during the pandemic. As moms, we all want the best for our kids. Thank you SO much for showing me how to make our entire family healthier & happier, Kim!
C.G.
I couldn't be more grateful that I found Kim! She is the utmost professional, a wealth of knowledge, a nurturing guide, and a caring soul. I felt completely seen and heard during our conversations, not regarded as another case or number, but as a human being that could be healed. She addressed every aspect of my lifestyle with care and consideration, then presented simple, natural, and helpful solutions that I could easily introduce into my everyday life. She has fully supported me on my personal journey of being healthy, powerful, and thriving. I'm so grateful for the newfound awareness she has brought to my life. Thank you Kim for your expertise, direction, and kindness!
T.W.
I feel so blessed to have worked with Britesquare. When Kim started coaching me I was suffering from severe inflammation, sugar addiction, and feeling the effects of taking oral steroids over a prolonged period. I was on the fast track to developing an autoimmune disease! I had seen multiple doctors who were happy to treat my symptoms with immune-suppressing drugs, but weren't motivated to understand and fix the cause of my health problems. Kim guided me in building a plan to identify and address my health issues. Kim educated and coached me in such a way that instead of feeling lost and frustrated, I felt empowered. Kim's enthusiasm about clean eating and our body's amazing ability to heal itself is contagious. My family and I live healthier and fuller lives thanks to Kim.
J.N.
I have been consistently impressed with Kim’s knowledge and dietary plans to fit our lifestyle. Most recently, Kim took the time to work with me on what my family takes as supplements and how we can eliminate or decrease our supplement usage by incorporating better foods into our diet. Her approach is straightforward and easy to understand. There have been times where I have felt intimidated by food selection and supplements, but Kim makes the process easy and enjoyable. Kim is an excellent health coach for individuals or families with little, or extensive, knowledge of their nutritional needs. After our meetings, I am more confident in making intelligent decisions for our health goals and look forward to continuing to work with Kim.
K.C.
Working with kim is like talking to a really good friend who really cares about you achieving your health goals. She took the time to listen to my concerns during my perimenopause journey. Her suggestions were always thoughtful and manageable in a way that didn’t make me feel intimidated to implement them in my real life. The supplements have made a huge impact on my symptoms and after just two months, I’m basically symptom free - no night sweats or insomnia! I cannot thank kim enough for her insights and understanding of the challenges that we face during this tricky time. I’ve explored many resources during the time that I’ve struggled with these symptoms and none have helped or compared to my experience with kim. I am forever grateful!!
K.P.
Kim, our visit today was great. I continually feel the “best” each time I leave your office. There is something very special that happens that I just can’t put into words. I thank you for helping me get to where I am. I have lost 15 pounds, my cholesterol has dropped 42 points and my blood sugar is now in optimal range. You are truly such a beautiful, warm young woman! The information and support you have given me has changed my life. It is so different than any other program I have ever been a part of. Thank you from the bottom of my heart!
K.W.
Kim’s work has significantly improved my gut, and importantly, my overall quality of life. Before consulting with Kim, my gastroenterologist did a general stomach exam showing nothing wrong or alarming. However, I was regularly experiencing stomach pain, gas, bloating, diarrhea, and constipation. This caused anxiety around what I could eat and locating a bathroom if needed. I often canceled plans and was very upset with my lack of freedom. A few weeks into Kim’s protocol, I had regular bowel movement and significantly reduced bloating and stomach pain. This improved my lifestyle and mood. I am thankful I was able to find Kim as she significantly improved my life. My digestion is no longer something I worry about which allows me to live life to the fullest. I am happier and less stressed which has been something I’ve struggled with for many years. Thank you Kim!
P.K.
When I started Kim's coaching program, I was at my lowest point. Overwhelmed by a major life change, a new endometriosis diagnosis, severe perioral dermatitis, and constant feelings of sadness and low energy, I desperately needed support. Kim truly came into my life at the perfect time, offering faith and a path forward. Her extensive knowledge of the body's functions and supplementation is truly impressive. Kim's program is remarkably easy to follow, and the results have been transformative. I am now off all antibiotic skin products and my personalized diet has also significantly reduced my endometriosis inflammation. Kim guided me through every step, helping me regain my "light" and truly feel like myself again. If you are struggling and searching for answers, I cannot recommend Kim's program enough. She will illuminate your path to healing.
