My guiding principle is the Mayo Clinic value that “the best interest of the patient is the only interest to be considered.” I live in Oconomowoc and continue to support local organizations such as St. Jerome Parish, the local Boy Scouts, and the Lake Area Free Clinic. I practice what I preach by staying active by marathon running (with the 2011 Milwaukee Lakefront Marathon being the most recent). I am a father with five children which allows me to bring personal experience to the pediatric advice I give.
