Chiropractic Life Center has been in our location for over 30 years. 


I entered in to the Chiropractic profession with a deep sense of compassion for those struggling with various health issues that in many cases allopathic medicine seemingly could not address. I am intent on really listening to my patients as I believe that is the most important aspect of a good examination. I am dedicated to treat each patient with respect and attentiveness focusing on each one as a complete person. I look forward to providing excellent care for my patients.

I have been in family practice for nearly 20 years. I have patients of all ages from new born to the very elderly. My very gentle instrument adjusting technique is well tolerated by all and very effective even in the most difficult cases. I utilize both Neuromechanical Innovations Impulse IQ and Activator Method Chiropractic Techniques. I am committed to keeping up with the most current research in the Chiropractic profession.

I have been married to Janine for over 34 years and I have 3 grown children and 3 grandchildren. I like to go camping, hiking, hunting and fishing with my kids and grand kids (when available) in the great northwest. I also like to go skiing on occasion. I am active with my church family and am involved with Campus Ministries at one of the local universities.
