Our Doctors

With more than a century of combined experience, we bring powerful expertise to each patient and your unique set of needs. Our doctors serve as consultants, expert lecturers, and industry leaders. We draw from the decades of experience our senior doctors hold, and the emerging techniques our younger partners bring to us from their recent educational experiences. The IPM team’s services include advanced interventional pain management procedures, psychological support, functional restoration and injured worker care and support.
