The bottom line is Mast Cell Activation Syndrome (MCAS) is complex. And while each person’s path looks different, there is a framework of understanding that helps 95% of our clients. You’re not alone in this. And you don’t have to keep piecing it together by yourself. We’ve been exactly where you are, and we spend every day helping people with MCAS. Here, you aren’t just the odd one out as a sensitive person; you are our entire community.

Two of our most-loved courses, plus live time with our team to help.
This is the part that’s just for bundle members. Get exclusive savings on the courses PLUS two live conversations built entirely around what you just learned, so you can bring your questions and troubleshooting needs!Â
This is the same framework we use, one-on-one, with our most sensitive clinic clients in a package you can return to as often as you need to. And move through at your own pace.Â
You’ll come away understanding:Â

Our co-founder, Beth O’Hara, spent over $250,000 and thousands of hours learning to understand and support Mast Cell Activation Syndrome on her own journey. And Mast Cell 360 was created from that experience and the desire to build a community of support.
The rest of our team used this same information to address their own MCAS and Mold Toxicity issues. Often with profound improvements. This is part of why we are so passionate about what we do. Â
We understand this struggle firsthand.
Everything in this bundle comes from what we’ve learned the hard way, refined over years of working with hundreds of the most sensitive clients.
We built these tools because we know what it’s like to be exhausted, reactive, and lost in the swirl of information (or lack of it). Â
We know people need strategies that work. And we don’t want anyone else to have to wait years or spend thousands of dollars to start finding a way forward. We built this for you.
Now, let’s meet the health coaches who will be guiding your live group coaching sessions.
Jamie is an MC360 Health Coach with a calm, encouraging presence. She draws on her personal healing journey and MC360 training to empower clients with foundational strategies, helping them take small, steady steps forward.
Kam is an MC360 Health Coach with a thoughtful, compassionate approach. She combines her MC360 professional expertise and personal lived experience with MCAS to guide sensitive clients through meaningful steps grounded in respect for each individual’s journey and pace.

and more!
I am a fellow holistic provider and I can’t say enough about this program. Since I tried it, I have been referring most of my clients this way. Mast Cell 360 does a fantastic job of putting all the pieces together in a comprehensive and easy to follow manner. This course contains a hugely valuable toolbox – anyone with any type of health ailment should start their healing journey here!
Amber W
I was barely sleeping at night and my body was so full of inflammation. I began to recognize and understand MCAS and other underlying hypermobility issues that I had. The supplement recommendations were also a game-changer for me, and I was finally able to break out of my long cycle of pain and inflammation. Mast Cell 360 truly is on the cutting edge of this field, and I am so grateful to them for it.
Gail T
I cannot say enough about Kam’s knowledge and compassion in helping me deal with my MCAS diagnosis. I was so afraid I could not accomplish a balanced body. She made me feel seen and that I was not alone for the first time in months of struggling. She showed compassion and shared part of her story to encourage me. She taught me how to slow load medications – a revelation! She left me feeling that with help like hers I COULD get better.
Alice P
My histamine levels are way down, and I’m feeling much better after working with Mast Cell 360. I recommend them for anyone who is experiencing health concerns and who would like a holistic approach that addresses the whole person!

MC360 Health Coach Jamie was so helpful. I had no idea all the things that were going on besides being overwhelmed and she was able to sort through them. With great guidelines to follow.
Crystal D
I was diagnosed with MCAS several years ago but have been struggling with symptoms for over a decade.The support, understanding, encouragement, and resources Mast Cell 360 gives its clients are unparalleled. The greatest gift Mast Cell 360 gave me was showing me that I am not alone in my MCAS battle. I am beyond grateful for Mast Cell 360 and recommend it to anyone struggling with MCAS. You are not alone.

No code needed · Lifetime access to both courses & replays
Is the bundle really cheaper than buying separately? Yes — $249 for both courses instead of $394, and the two live group coaching sessions (valued at $198) are only available as part of the bundle.Â
Are the coaching sessions private, one-on-one calls? These are live group sessions, so you’ll be alongside other members of our community and our Health Coaches. Replays will be available for those who cannot attend live, as well. Â
Should I take the courses before the sessions, or does it matter? We’d gently suggest at least starting to work through the course before its matching session, so your live time goes further. But you’ll have lifetime access, so there’s no wrong way here.Â
What if I’m too sensitive to tolerate most supplements? The Top 8 course walks through the most common reasons people struggle to tolerate supplements, and nervous system dysregulation is one of them! That’s why we are pairing these together. And your coaching session sets aside real time to troubleshoot things like this with the Health Coaches. Â
Still have questions? Reach out to us at support@mastcell360.com and a member of our team will get back to you as soon as possible!

Since beginning the Mast Cell 36o 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. They helped me choose the right supplements to support my recovery.
