Additionally, the majority of TCOM students sit for USMLE Step 1 where they also performed at or above the national average of all allopathic medical schools.

Dr. Peska’s Perspective on Medical Education: “Although comfortable with and experienced in clinical practice management and oversight of a modest research enterprise, my core interests are in curriculum and instruction and team development. The application of evidence-based principles of learning to medical education has enhanced institutional effectiveness at TCOM. With several complimentary degree programs on the health science center campus and in the community TCOM has successfully partnered internally and externally to promote inter-professional practice. Our team has been invited to present its strategies and outcomes in the United States and overseas.” – Don N. Peska, DO, MEd, FACOS
