Family Medicine and Patient Care Approach
Family medicine provides broad healthcare for people of different ages rather than concentrating on one particular organ or condition. Regular visits may include preventive screenings, immunizations, evaluation of new symptoms, medication monitoring, chronic disease follow-up, and decisions about when specialist care is appropriate.
Dr. Sharma’s approach emphasizes relationship-based and physician-led care. His professional work has included preventive medicine initiatives, patient-centered care models, healthcare quality improvement, and mentoring medical students and residents.
Because his practice also includes pediatrics, families may receive care for both children and adults within the same primary care setting. This can support continuity while giving the physician a broader understanding of family health history and long-term medical needs.
Education and Credentials
Dr. Sharma earned his Doctor of Medicine degree from St. George’s University School of Medicine in 2005. He later completed family medicine residency training at William Beaumont Hospital in Michigan.
He is board certified by the American Board of Family Medicine and the National Board of Physicians and Surgeons. He is also a Fellow of the American Academy of Family Physicians and has participated in professional leadership and physician advocacy through family medicine organizations.
