Change the Future of MCAS Care

become a certified practitioner

We’ve heard from so many practitioners who want to get certified in the Mast Cell 360 Method—and we’re thrilled to share that it’s coming.

Our late founder, Beth O’Hara, developed the Mast Cell 360 Method before most of the world had even heard of Mast Cell Activation Syndrome. Her groundbreaking, root-cause approach has become the standard of care for MCAS and related conditions. Practitioners trained directly by Beth continue to use this method today to support hundreds of clients around the world, including some of the most complex and sensitive cases.

This training will be ideal for MD’s, NP’s, Chiropractors, nervous system practitioners, therapists who do nervous system work or care for those with chronic illness, health coaches, and other types of practitioners in similar healing professions.

We’re working to bring this training to a wider circle of professionals through an official Certification Program.

We hope to open enrollment in 2026 but stay tuned in case we are able to do so sooner. Spots will be limited, and we expect them to fill quickly, so be sure to join the waitlist by entering your email address below. Waitlist members will get early access and exclusive discounts.

*Please note this training will not be qualified for continuing education credits initially but we hope to offer this eventually. For the time being, practitioners can submit it to their governing board and may be able to get CE’s independently because of the high standard of the curriculum.

Participation and Commitment

As we mentioned, the Mast Cell 360 Program is a long-term program. Depending on your case, the duration of your work here may be anywhere from 1- 3 years. Are you willing to actively participate in follow-up appointments approximately every 6-12 weeks during that time, as needed?

Technology

We are a small clinic without an IT department. Are you comfortable with using computer-based technology (e.g., Excel, our Practice Better Client portal, Supplement Store and an on-line ordering system for labs).

 

Are you willing and able to embrace technology during your healing journey? 

 

Reporting

Success with the Mast Cell 360 program relies on tracking how you are doing, in between appointments as well as keeping a journal of changes when you add new supplements, foods, or experience new stressors in your life. 

Are you willing to fill out a changes journal and progress report, that may include daily tracking?
