About His Family

“My wife and I became interested in Bozeman after winter skiing trips to visit my wife's sister and her family who have lived in Bozeman since 2003. After living and training in Denver for 5+ years, we were looking for a community with a slower pace and easier access to the mountain sports we both love. Being an avid fly-fisherman, hunter, and skier, I welcomed the opportunity to develop a practice in a locale where I could pursue my interests outside the office. Since opening the practice in August 2006, I have been blessed with a thriving practice and two children, who keep my wife and I continually entertained and challenged!"
