Services
Integrative Medicine
Our integrative medicine approach combines conventional diagnostics with natural therapies to address chronic conditions. By evaluating biochemical individuality and lifestyle factors, we create customized treatment plans that may include nutritional interventions, herbal medicine, and mind-body practices. This evidence-based methodology effectively manages conditions like autoimmune disorders, metabolic syndrome, and chronic fatigue while emphasizing preventive care and patient education.
Seasonal Detox Programs
These structured detoxification programs align with seasonal transitions to optimize bodily cleansing. Utilizing targeted nutrition, supplementation, and lifestyle modifications, we help eliminate environmental toxins and metabolic waste. Participants receive comprehensive support including meal plans, symptom management strategies, and post-detox reintegration guidance. The programs address modern toxin exposure while incorporating traditional cleansing principles adapted for contemporary health challenges.
Nutritional Counseling
Personalized nutrition plans focus on restoring cellular health through whole foods and targeted supplementation. We address food sensitivities, digestive health, and metabolic imbalances using elimination diets and functional testing. Our approach emphasizes seasonal eating patterns, acid-alkaline balance, and nutrient-dense meal planning to support energy production and immune function while addressing specific health concerns like inflammation and hormonal imbalances.
Weight Management Programs
Our weight management approach identifies underlying causes of weight gain beyond calorie imbalance. Through comprehensive assessments, we address hormonal factors, food sensitivities, and metabolic disruptions contributing to weight issues. Programs combine nutritional reeducation, detoxification support, and lifestyle modifications to achieve sustainable results while improving overall metabolic health and preventing weight-related comorbidities.
Health Coaching
Individualized health coaching supports long-term lifestyle transformation through behavior modification and skill development. We provide guidance on stress management, sleep optimization, and mindful eating practices. Our coaching integrates accountability systems with educational resources to help implement and maintain health-promoting habits aligned with personal goals and biological needs.

Dr. Haas has been the primary care physician for myself and my wife almost since we moved to San Rafael, back in 2014. He is more wise, knowledgeable, patient and caring Lohan any other doctor I have ever had; he takes the time to really listen, understand our unique issues and needs. Highly recommended!

An easy, comfortable experience with Dr. Hass. As an MD I really appreciated his naturopathic approach to medicine, you definitely get the best of both worlds, medicine and alternative considerations for your best outcome.

Personable, kind, supportive and patient! (not to mention efficient!) Super pleased to have signed on to Dr. Elson Haas' practice for my Primary Care physician! I mean, how often does one get to hear from the Doctor directly about an issue? Thank you so much for your care and genuine interest in my well-being/issues to Dr. Haas and the rest of the staff I've had the pleasure to deal with for my 1st visit!

I had my first meeting with Dr. Haas last week and it was one of the best meetings with a provider I have ever had. Prior to seeing Dr. Haas, I had been feeling invisible to medical providers and more of a number than a person. I have had longstanding health concerns for most of my life with little to no resolution or validation. Within minutes of talking with Dr. Haas, I felt seen and heard for who I am as a whole person and he took an interest in finding the source of my concerns and was immediately proactive.

He referred me to a NP in the office who I will see this week. I think this is the beginning of a new journey to be the best, healthiest version of myself and I couldn't be more excited or more grateful!

Dr. Haas and his team were well organized and attentive. Instead of emphasizing on pre-existing health issue, they were focusing on building a good foundation. I have couple more appointments with other partitioners at this office and looking forward to continue working with team at PMCM.

Dr Haas has a staff with a huge variety ofskills. I just did allergy testing and am looking forward to an easy treatment. This can help take the inflammation down in my body. Dr. Haas has a good idea of where to look to help his patients.

He was kind and open hearted with a lightness. It seems clear he cares and enjoys being with his patients. Each person in the office was kind and helpful. We are delighted to have found this special place. Thank you.
