Ethos Primary Care

Ethos Primary Care is a New Jersey medical practice focused on preventing and reversing chronic disease through lifestyle medicine. Founded by Ron Weiss, M.D., a physician dual board-certified in internal medicine and lifestyle medicine, the practice combines primary care with coaching and education. Its approach emphasizes personalized, preventive care and a nutrient-rich diet of whole, unrefined plant foods, connecting human health with the natural world. Ethos operates on a historic working farm in Long Valley, where it also grows organic produce and supports community education.

The practice offers in-person primary care and telemedicine, alongside programs for different needs and levels of commitment. These include a self-guided 2-Week Challenge, a medically supervised 30-Day Detox, a year-long Lifestyle Foundation program, and the Mindful Living Journey. Additional services include lifestyle education classes and Mindfulness-Based Stress Reduction, intended to support behavior change and well-being. Ethos also shares learning resources, events, and patient stories, and connects visitors with Ethos Farm to Health and the Doctor’s Farm Market, a partner offering USDA-certified organic produce.
