Dr. Matthew Amundgaard DC


Hi, I am Dr. Matt. I have been a chiropractor since 2006. I graduated from Northwestern Chiropractic College in Minnesota.

Why I became a Chiropractor: I got started with chiropractic at the age of 7 when I was getting chronic headaches, and nothing was helping. I literally tried everything. You name it I tried it. Finally, was taken to a chiropractor and found tremendous relief! I also saw what it did for my sisters in their sports as well as the positive effect it has on my mother’s health. I was truly hooked on chiropractic! Since then I enjoy seeing others find great relief and get their lives back through our unique approach here at Trinity Chiropractic. What we do here is so special you will be hard-pressed to find it anywhere around town.

I love Arizona! I spend time with family and friends on the awesome trails we have here hiking and biking, or up at Lake Pleasant doing some paddle boarding. Don’t be surprised if you see me around town enjoying some of our many great restaurants here or down at a baseball game.

My Health Philosophy: I am a chiropractor for the joy and excitement of seeing improvement in patients who couldn’t find help elsewhere. Watching patients regain their ability to perform activities that they love but had become unable to enjoy prior to finding chiropractic, is something special. I look forward to many more years filled with teaching people how they can become healthy and stay healthy, which will allow them to enjoy life throughout their years.

A little more about the Iszler’s and Trinity Chiropractic…

Dr. Iszler is committed to providing people in the West Valley with gentle, effective corrective chiropractic care.

He would love the opportunity to share the life-changing benefits of chiropractic.

She recently moved back to the area from Tennessee and is offering her skills as a licensed esthetician, certified lash artist, certified acne specialist, and a certified master sugarista!
