Dr's Coster, Graziano and Yoon are board-certified by the American Board of Foot and Ankle Surgery.
To become board certified in his/her specialty, a physician must spend several years after medical school receiving supervised in-practice training. In addition, all specialty boards require the passage of a written and oral exam.
All board-certified physicians are required to show maintenance of competence by evidence of lifelong learning and ongoing improvement of their practice. This requires the physician to show evidence of knowledge and judgment, commitment to lifelong learning, and involvement in a periodic self-assessment process and show evidence of self-evaluation of performance in practice.
