Buffalo Medical Group : Physicians

All of the physicians within the Buffalo Medical Group are Board Certified or Eligible in their respective specialties. Physicians attracted to the Buffalo Medical Group, P.C. have a long history of quality care, innovation, research and teaching. Many of our physicians hold clinical appointments at the University at Buffalo School of Medicine and Biomedical Sciences.

Most Buffalo Medical Group physicians are on the staff of Kaleida Health hospitals (Buffalo General, Millard Fillmore Gates, Millard Fillmore Suburban, Women and Children’s, and DeGraff Memorial). A number of our physicians have privileges at Catholic Health System hospitals (Sisters of Charity, South Buffalo Mercy, Kenmore Mercy, and St. Joseph’s). Some of our physicians also have staff privileges at other hospitals in the community. Please check with your physician regarding the hospitals with which he or she is affiliated. Many of the primary care physicians in the Buffalo Medical Group use a hospitalist (a physician who specializes in caring for hospital inpatients) to coordinate your care while you are in the hospital. We currently have three full-time hospitalists.
