Sports and fitness have always been a big part of Dr. Dan’s life.

Chiropractic care and massage therapy were major factors in Kinsey’s recovery, and she decided that what was really important to her was the ability to help other people banish pain and get back on their feet.

Kinsey never fails to see the results that patience and commitment to massage therapy and healing brings. She says, “I love the connections that massage fosters, and understand the importance of communication and collaboration in providing the best treatment.”
