Bio:
Dr John is a father of 5 children, husband and a family physician. He grew up in Northern Virginia and has spent most of his life here. In his youth, he pursued athletics (wrestling, football, boxing and more…) and developed an interest in human physiology and philosophy. Following his undergraduate work at George Mason University (GMU) he completed a Master’s in Biology at GMU. Thereafter, he worked in the biotech industry for Human Genome Sciences in their Oncology division. This experience eventually lead him to understand his true passion - helping others achieve a long and healthy life.

After completing residency, he started Vantage Primary Care. A private practice that cared for patients admitted to Fairfax Hospital. During this time, he learned a lot including how health systems really operate and how healthcare consolidation harms the patient.

Dr John started Summit Direct Care with his wife, Diana, as they believed a better approach to health was truly needed. One of the issues facing our society is over medication and lack of a root cause approach to health. The problem is few doctors have the time, incentive or knowledge to help patients reverse disease or build a strong health foundation. Summit Direct Care was founded so you can have a doctor with the time, knowledge and desire to help you craft a personalized plan to reverse and prevent disease.

Dr John works with his patients in a collaborative manner, to get to the root cause of their problem(s), then creates a detailed and personalized plan. He focuses his efforts on optimizing your health through lifestyle and reversing chronic disease whenever possible. He practices broad spectrum family medicine (care for all ages) and has a passion for musculoskeletal medicine, wellness/preventative health, lifestyle medicine and nutrition.
