For Clinicians

We’ll lay the foundation for better treatment success.

We all see patients with myriad complaints in multiple organ systems for whom tests and treatments have not identified a clear diagnosis or effective treatment plan – the complex, mystery patients. I know from experience the frustration when the same patient is in the office again and again and you’ve run out of recommendations, but see they’re suffering.

OCC’s Functional Medicine approach prioritizes regulation of the autonomic nervous system.

Polyvagal Theory explains the physiologic impacts of chronic stress, developmental trauma, and social determinants of health; immune systems are dysregulated away from healing because the ANS is in a state of protection.

We work with people one-on-one and in small groups to foster social connection and relational safety, which lays the groundwork to bring the immune system back online for health, growth, and restoration via regulation of the ANS. This foundation optimizes the effectiveness of our Functional Medicine interventions for improving heart rate variability, nutritional status, mitochondrial efficiency, elimination patterns, intestinal microbial diversity, healthy sleep, and exercise tolerance.

Our patients have histories of poorly understood symptoms and either no diagnosis or a multitude of diagnoses.

Recent research suggests that many of these patients have Mast Cell Activation Syndrome (MCAS) (either primary or secondary) or Mast Cell Disease (MSD) as an underlying factor that creates an environment of chronic inflammation. Typically, these patients complain of symptoms in multiple organ systems (often including anxiety and/or depressive patterns) and have sought care in a variety of disciplines, which is consistent with an MCAS presentation. (Afrin, LB, Never Bet Against Occam: Mast Cell Activation Disease and the Modern Epidemics of Chronic Illness and Medical Complexity, 2016)

These challenging patients often respond unusually to treatment attempts; their reactions can be paradoxical, they can have no response at all, or they don’t tolerate even low doses of medications. Until their mast cell membranes are stabilized, they often cannot tolerate the treatments they need. We work with patients to stabilize the mast cell membranes via autonomic nervous system regulation as well as dietary, supplement, and medication interventions.

We specialize in supporting patients with complex, chronic inflammatory conditions.


We require our patients to have a PCP and we appreciate the opportunity to collaborate with providers of other disciplines.

Diagnoses we support by specialty

Many of the symptoms causing a person with autonomic nervous system dysregulation to be referred to a specialist do not meet diagnostic criteria for a diagnosis. These patients have often had this same experience in multiple organ systems and with multiple specialists, and are often not receiving treatment because of lack of diagnosis, or are responding oddly to treatments.

“As a trauma therapist with some (not extensive) exposure to Polyvagal Theory, I was stunned by the presentation “Removing Obstacles to Healing” with Jessica and Micaela. I had never before understood the relationship between stress/trauma and the immune system which they laid out so clearly. But then, I was completely blown away with their [experiential group education and practice] series on the Polyvagal Theory. I learned about my own system as well as how to recognize dysregulation in my clients at a much more subtle level than before.”
