About

Bio

My primary focus outside the office is my family. I have been married for 29 years this year (2011). We love to spend time at home, in the yard, involved in church and whatever our kids are doing. I also am an Apple geek, a music lover, and I love new restaurants, of which Portland has many.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
