Every day, more and more people reach out to us seeking effective and compassionate approaches to Mast Cell Activation Syndrome and related conditions. 

As our waitlist continues to grow, we’re reminded that we’re a small but mighty team but millions of people around the world are suffering from MCAS. 

Our vision has been to reach as many people as we can who are needlessly suffering. 

As a small team, though, we’re limited in how many appointments we can take each week. One thing that makes our practice stand out is that we don’t try to cram in 30 clients a day and just spend 15 minutes per person. 

You deserve the time, care, and attention to your case.  

It’s what our co-founder, Beth O’Hara longed for when she was severely ill. And it’s one of the driving factors behind our mission for Mast Cell 360. 

But here’s the good news. And it’s something that we’re really proud of.  

Over the years, after working with hundreds of clients, we’ve developed a method that serves as a successful foundation for helping those with MCAS, Histamine Intolerance, and Mold Toxicity regain their lives. 

What we’re most proud of is that this method, the MC360™ method, is teachable and repeatable. 

What does that mean exactly? It means when the right type of practitioner is trained to follow this method, that practitioner will get the same great results we’ve seen now with well over 600 clients. 

And it means we can empower other practitioners to help fill the growing need for those with MCAS and other related conditions. 

That practitioner has to be just the right practitioner, though. Someone who understands the method is a foundation, but also gets that each person is unique. This requires a great deal of skillfulness, knowledge, and empathy. 

To be able to meet the growing numbers of those who need help, we’ve carefully selected practitioners who are the best of the best to work with the Mast Cell 360 practice. They have the skills, knowledge, and empathy to successfully implement the MC360™ method. 

The MC360™ method has helped over 600 clients regain their lives, hopes, and dreams. It’s this method that gets results. 

Each of our Mast Cell 360 practitioners have been extensively trained in how to evaluate complex cases of MCAS for individual root factors and how to implement the MC360™ method appropriately for even highly sensitive people. 

We work closely alongside each of our Mast Cell 360 practitioners, supporting them with the MC360™ method we’ve seen work for so many.  

Each of the practitioners also brings their own knowledge, proficiency, and expertise to the practice, which further expands our skillset and offerings.  

We’ve found people with complex cases of MCAS, Mold Toxicity, and Lyme recover much faster with a team of dedicated, experienced, top-notch practitioners.  

As you can imagine, this field is exponentially expanding to meet the complex needs of those with MCAS. This is another reason we’re stronger as a team. 

Our vision is that our caring practitioners will contribute their own skillsets to the MC360™ method to continually expand our service offerings and push the field ahead even further. 

This diversity of backgrounds means our practitioners can co-consult on even the most challenging cases to serve you even better. You’re getting an excellent support team every step of the way. 

As a practitioner team, we meet regularly to review cases and offer support to one another on tough cases. This allows our team to continually learn more and more.  

We strongly believe our mission is to help others, just like you, regain health. 

But alone, we can only help so many. That’s why it was important for us to teach the MC360™ method to other practitioners so we can serve more people who are suffering unnecessarily. 

At Mast Cell 360, we are all 100% committed to ensuring you have the highest level of quality care and support we can offer.

Here are some words about Alex from his clients: 

Dr. Bingham is a brilliant doctor. He understands the deep roots of chronic illness much better than most MDs. Because of this, I have made a lot of progress in many areas with SIBO, Chronic Fatigue, food sensitivities, hypothyroidism, methylation and histamine issues to name a few.  He stays up to date with research in the medical/ alternative medicine field and is very open to information that I have come across through my own research. I am very grateful that I have him in my life.  He has helped me improve the quality of my life in a big way. Dr. Bingham is the best.” -MaryAnn A. 
- MaryAnn A. 
Dr. Bingham is the best of the best!   He takes his time, listens and truly cares. He gets to the bottom of the issues and is truly the most amazing doctor I have ever met.  He will keep you in there until your problems are analyzed thoroughly and you will leave with a solution plan. If there were ten stars, I would give him a 10!!!!
- Marie C.
I've been battling a mystery illness for 3+ years with no answers. I've been to all the top doctors and hospitals in Boston, with no answers. FINALLY I was referred to Dr. Bingham, what a DIFFERENCE in concern, interest and care. I feel so confident with him trying to get to the bottom of it, because I know he can! I heard he closed his practice to new patients, but he is one hell of doctor!!! Can't say enough amazing things about him!
- P.
Dr. Bingham is one of the best doctors I’ve ever worked with. His wealth of knowledge is outstanding, as is his kind manner.
- Betsy T.
Phenomenal doctor...fabulous staff...I cannot say enough about this amazingly thorough, intuitive, brilliant, caring doctor. He has made my life better. I trust him implicitly with my … needs, kindness and clear information at every visit...he is the definition of a healer in my experience.
- Joanna F.
I started seeing Dr. Bingham this past January to work to regain my health after being exposed to mold in my luxury apartment rental in Boston.   Every visit with Dr. Bingham has been informative and helpful, and having him and his excellent staff as a resource during this frightening time has been so comforting.  Becoming well again is not an overnight process, but little by little Dr. Bingham is working hard to resolve the various issues I have due to my mold exposure.  I cannot say enough positive things about this excellent Dr.
- Megan G.
I have been seeing Dr. Bingham for several years now for a chronic medical condition. He is one of the most caring, concerned, and intelligent doctors I have ever been to. He takes the time to review your medical history and takes it into account when partnering with you on a plan of care. He is very thorough and not afraid to try new things. The care he provides is top-notch!
- Jen F.
I was very happy with my appointment with Alex. He was kind, knowledgeable, and extremely thorough. He offered a valuable suggestion of washing the coating off of a tablet that I was reacting to. That has already helped me. He explained that he likes to get a lot of information in the beginning, and so he ordered many tests. He also made good suggestions of supplements to add. I feel very grateful to be working with him.
- Beth R.
It was a pleasure meeting with Alex and felt like I was in good hands with all of his experience! He is also a very compassionate provider and I'm excited to continue to work with him.

My appointment was great. Alex really listened to me and understood all the nuances of what I’ve been going through. I really liked how he picked up on how certain supplements weren’t working for me and said we have to go another direction. I felt very optimistic after the appointment and confident in his skills. I already feel a difference with the Claritin. Thank you all so much.
- Rob K.
Alex was amazing, he was empathetic, informative, knowledgeable, kind and helpful. Alexa really liked him, felt that she learned a lot and was hopeful after the appointment! We don’t have any suggestions for improvement, just lots of gratitude for the help!

LaShay McKeel, LMSW
Mast Cell 360 Emotional Support Coach
Safe and Sound Protocol (SSP)

LaShay McKeel, LMSW, provides emotional support to individuals managing the stress and neurological effects of MCAS and related conditions. Feel free to call her “L”. 

She employs techniques such as embodied connection and rewiring, breathing exercises, guided meditation, education, and more to calm the nervous and limbic systems. She also walks with clients in navigating common challenges associated with MCAS, Mold Toxicity, and the experience of living with invisible illness. 

LaShay also offers the Safe and Sound Protocol (SSP), a method that uses sound to foster a sense of safety. Many people with MCAS and similar conditions have struggled to feel secure enough to heal, due to trauma and life experiences that have kept their nervous systems in a constant state of alert. SSP utilizes specially filtered sound designed to help calm the nervous system, allowing the body to focus on healing. 

Having personally experienced a sensitized nervous system and a range of related impacts, LaShay is also deeply familiar with the effects of MCAS, fibromyalgia, chronic fatigue, Lyme disease, and similar conditions on individuals’ lives. She has a functional view of adaptations the brain makes, along with its ability to heal when well supported. 

LaShay’s education and training include:  

  • 7+ years of experience in community social work with a focus on asset-based community development and case work providing person-centered service coordination and advocacy for care. 
  • 3+ years of specialized learning and practice in mind-body medicine, focusing on the nervous system, emotional regulation, and safety.
  • 3 years connecting individuals to tailored rehabilitative resources.
  • Experience supporting clients with chronic illnesses and health challenges, including safely reprocessing trauma and seeking to address root issues.
  • M.S.S.W. in Social Work
  • Bachelor’s Degrees in Psychology and Sociology
  • Licensed Master of Social Work (LMSW- Associate-level Social Worker)
  • Neuro Somatic Yoga & Bodywork provider; Registered Yoga Teacher (RYT-200)
  • Integrated Somatic Trauma Therapy (ISTT) Coach 

LaShay’s work centers on guiding individuals to rediscover or learn for the first time how to exist in a more integrated, regulated state, while empowering them to take an active role in their own healing journeys.

Here are some words from our clients about Emotional Support and SSP:

I have used SSP as a foundational modality for supporting the nervous system.  What I like about SSP is you don’t actively have to work at it.  You listen to the music while the program operates in the background.  I also like the fact that after completing the 5-hour regimen you can go back to it whenever you want. I found SSP to be useful to calm my anxiety and improve insomnia. I would definitely recommend it to others…It works well for MCAS sufferers. I never experienced side effects.  Nervous system dysregulation is very common with MCAS and listening to the filtered music helps to calm things down.  I believe that SSP has helped to improve my vagal tone and find that I’m less reactive to foods, have better digestion, and sleep.  While I cannot attribute all these improvements to SSP I know it has played a positive role as I continue to recover.

Kam Uchimura
Health Coach

Kam Uchimura - Health Coach at Mast Cell 360

Kam Uchimura brings both personal and professional experience to the community as a MC360 Health Coach.

Her MCAS journey began with the sudden onset of multiple, severe chronic illnesses affecting most of her family, which quickly escalated to reacting to everything except distilled water, an inability to eat, and discussion of a feeding tube. Doctors could neither explain the conditions nor provide solutions. So, determined to find answers, she began researching. Which ultimately led to Mast Cell 360 and Beth’s teachings—paving the way for those first critical steps in the right direction and a road to significant healing.

This path has not only deepened her understanding of MCAS, Mold Toxicity, multiple food intolerances, dysautonomia, autoimmunity, post-viral illnesses, and other chronic conditions but developed compassion for those on similar roads looking for answers.

Kam’s approach is deeply informed by both her personal experiences and her professional training. With a Bachelor of Science, and a lifelong interest in deep nutrition and lifestyle habits as the foundation for health, Kam has successfully reversed her own ‘incurable’ health issues in the past, as well. 

Each of these journeys have fortified her belief that with the right supports, many seemingly impossible things are often possible.

She is passionate about learning, collaboration, community, and empowerment. Kam’s coaching style combines science-based education with a deep respect for each individual’s unique story.

A Few More Words From Our Clients:

In July 2020, my body broke down and would no longer tolerate food. I had developed severe reactions to every food I tried to eat and finally got so limited that I was down to only 1 safe food: oatmeal. Despite the litany of tests and medications - I was seeing no improvement. My body was suffering from the lack of nutrition, and I was desperate for solutions. I had dropped 25 pounds from my already lean frame and was literally fading away before my own eyes. I was foggy brained, I had developed thyroid issues, had terrible anxiety, and had shortness of breath all of the time... In March of 2021, I was able to have my first appointment at the Mast Cell 360 clinic and I knew immediately that I was in the right place. They listened and took the time to dig deep with me.  They helped me not only come up with solutions on how to get my systems calmed, but they also made sure my emotional/mental health was not forgotten about either.  Now, I have gained back all the weight that I lost and am now back to my "normal" weight range.  I no longer have anxiety like I used to. I also have been able to add back over 25 foods into my diet and have added many supplements as well.  Even more than that, my thyroid has stabilized on its own, I'm back to running three miles at a time, and enjoy hiking most days of the week.  I'm able to run and play and have adventures with my three kids like sand sledding.  My family was even able to take an RV trip this past summer to visit family.
- Kristin L.
I highly recommend working with Mast Cell 360. Beth O'Hara and her staff are professionals that are exceedingly skilled at helping their clients return to outstanding levels of health. I am actually LIVING again! Before I started working with Mast Cell 360, I could barely walk. We live in a two-story house and there were many days I couldn't even get myself down the stairs.  Now, I'm taking ballroom dancing lessons! I'm also practicing yoga again and hiking in the woods. My heart and blood pressure have stabilized, I'm not experiencing brain fog anymore, and my skin and GI tract have improved immensely. And, I can't believe I'm sharing this, but my husband and I are intimate again.
- Pattie E.
Since beginning the Mast Cell 360 program 18 months ago I've experienced measurable improvements in my sleep and anxiety. I can now tolerate many more foods than before. My capacity for supplements is increasing. I have less bloating. My chronic constipation is resolving. The MC360TM Method is what sets this clinic apart. From the start, they focused on determining the root causes for my illness. They identified high oxalates as a problem and suggested a low oxalate diet. They developed a protocol for mold detox which was personalized for me. They helped me choose the right mast cell supplements to support my recovery. This method is different because it takes into account the special needs of sensitive clients. 
- Jerry W.
I’m thankful for the MC360TM approach of addressing the root cause while also supporting the body and mind for better overall health and wellness. This clinic offers a rare combination of compassion and first-hand experience with the symptoms I had. It makes all the difference in how they deliver care. 
- Deanna S.
