  • Biography



    For Dr. Koffman, the reward of being a physician is being able to share in his patients' lives. He feels the challenging and always changing science of medicine is the backdrop to the great priviledge of sharing in his patients' lives. He enjoys the opportunity to teach and learn from his patients, as well as share in their joys and sorrows. Dr. Koffman sees his role as facilitator and partner. Family practice allows him to establish close ties with his patients and their families. His goal is to help them navigate through their health-related concerns by providing them with the best resolutions and most informed range of options.

    my previous PCP was one of the worst doctors I've ever had. Dr. Kauffman was wonderful.
    Dr. Koffman has been my personal medical advisor for many years. I would like to extend my thanks to Dr. Koffman for his professionalism, diligent in diagnosis and finding remedies from cold to blood sugar. All and all, I would also like to thank St. Jude for the great medical and professional staff who served my family during the last 20+ years!
