I am a native Minnesotan and have practiced in Marshall, Minnesota since 1987. I have a special interest in Occupational Medicine and enjoy working with area businesses. My certification as a Medical Review Officer has allowed me to expand my Occupational Medicine practice to offer a full range of services including pre-employment exams, workers compensation evaluations, and supervision of state and federal drug testing.
