Dr. Erik Christian Petersen, DO

Dr. Erik Petersen, D.O., is a board-certified physician and founder of FirstCall DPC, where he leads one of the nation's most comprehensive physician-led ADHD programs for adolescents (14+) and adults. With more than two decades of experience across Emergency Medicine, Internal Medicine, Pediatrics, and urgent care since 2002, Dr. Petersen brings an exceptionally broad clinical perspective to diagnosis, treatment, and long-term optimization.

His ADHD practice is built on what busy professionals, students, first responders, and executives say they want most: a real physician who knows them, thorough evidence-based evaluations, individualized medication management, and structured monthly follow-up with PDMP review and direct physician access — never one-size-fits-all prescribing.

Beyond ADHD, Dr. Petersen focuses on Direct Primary Care and physician-led optimization, including men's health and hormone therapy, medical weight loss, metabolic and preventive medicine, and performance and …recovery. A former collegiate All-American football player, he brings the discipline, preparation, and accountability of elite athletics to every patient relationship. He is licensed across multiple states and cares for patients both virtually and in person.
