Why Board Certification?

Our physicians are board certified, experienced specialists. Certification in Family Medicine requires rigorous training and examination, and ensures that physicians stay current with standards of treatment and changes in the field of primary care. Certification is required by many hospitals and healthcare insurers.

U.S. physicians specializing in Family Medicine must further complete 3 accredited years residency in addition to their Medical Degree, before they are eligible to sit for Board Certification.

Our physicians are certified by the American Board of Osteopathic Physicians in Family Medicine.
