Kresser Institute

What Kresser Institute does

Kresser Institute is a privately held vocational training provider that educates licensed clinicians in functional and root-cause medicine. Founded in 2015 by Chris Kresser, MS, LAc, the institute operates as a Nevada LLC (Chris Kresser, LLC, d/b/a Kresser Institute) organized as a division of O'Shea Functional Health, Inc., and is headquartered in Las Vegas with a fully virtual operating model. Its core offering is the ADAPT Practitioner Training, Fellowship & Certification Program, a year-long, cohort-based program built around live patient case studies, small-group learning, and mentorship from practicing clinicians at the California Center for Functional Medicine.

The product portfolio also includes self-paced specialized courses (Functional Blood Testing, Functional Nutrition Mastery, Functional Hormone Mastery, and a women's hormone labs submodule), an alumni membership, and a public practitioner directory. An earlier ADAPT Health Coach Training Program was retired in 2022. The institute's underlying technology is a virtual learning platform with cohort-based curriculum delivery; no proprietary AI/ML capabilities or APIs are disclosed.

The business generates revenue primarily through enrollment fees for the multi-year ADAPT program (subscription-style, multi-year contract), one-time fees for self-paced specialized courses, and recurring alumni membership dues. Go-to-market is community-led and content-driven, relying on blog articles, a weekly email newsletter, free downloadable case-study e-books, graduate testimonials, and a discovery-call sales motion with a practitioner liaison team. The company is bootstrapped, with no external funding disclosed, and has trained 2,000+ practitioners across 30+ countries.

Broad incumbents

• Academy of Integrative Health and Medicine (AIHM): Interdisciplinary membership and education organization for integrative health practitioners. Comparable professional training and certification infrastructure.
• American Academy of Anti-Aging Medicine (A4M): Larger, established provider of certification training in anti-aging, metabolic, and integrative medicine for clinicians. Overlaps in clinician-targeted advanced-medicine education but with broader scope.
• Andrew Weil Center for Integrative Medicine: University-based (University of Arizona) fellowship and training program in integrative medicine for clinicians. Comparable learner audience with deeper institutional credentials.
• Function Health (Dr. Mark Hyman): Functional medicine-focused consumer testing and clinician ecosystem co-founded by a prominent functional medicine educator (who is also an endorser of Kresser Institute). Overlaps in functional medicine brand ecosystem and clinician audience.

Direct peers

• Institute for Functional Medicine: The dominant functional medicine training organization, offering certificate programs (Applying Functional Medicine in Clinical Practice, AFMCP) for licensed clinicians. Most directly comparable peer in clinician-targeted functional medicine education.
• School of Applied Functional Medicine: Online practitioner training program in applied functional medicine, also serving licensed clinicians. Direct competitor in the same online, cohort-style clinical training category.
• Functional Medicine Coaching Academy: Partners with IFM to train health coaches and allied professionals in functional medicine. Comparable online education model targeting functional-medicine-adjacent practitioners.

Others

• Cleveland Clinic Center for Functional Medicine: Clinical care arm at a major academic medical center treating patients with functional medicine approaches. Less direct on training, but a high-profile ecosystem participant whose clinicians and graduates overlap with Kresser's audience.

Emerging players

• Wild Health: Genomics-informed functional and longevity medicine practice with practitioner training content. Smaller scale than Kresser but competing for the same clinician audience.

Regional players

• Bastyr University: Accredited university offering degrees in naturopathic medicine, nutrition, and integrative health sciences. Comparable clinician education footprint with stronger credentials but degree-track rather than short-format training.
