Our Doctors


Dr. Casselman knows from firsthand experience just how valuable chiropractic work can be. He is an avid sportsman, enthusiastically participating in mountain biking, running, and skiing. All of these sports are fun and rewarding, but also took a toll on Dr. Casselman’s body through a number of sports related injuries. Long before Dr. Casselman moved to Highlands Ranch, a chiropractor in Crested Butte, CO was helping him recover faster and reducing his pain better than other treatments could. After realizing how much he could help people, Dr. Casselman went back to school and began studying to become a chiropractor.

He was surprised to discover that being a student was almost as hard on his body as being an outdoor sports enthusiast – he soon found that studying and listening to lectures for hours a day made his body stiff and sore, causing even more problems than when he was active. As a chiropractor, Dr. Casselman now helps patients overcome these problems for themselves. He’s a unique chiropractor because few have experienced both kinds of discomfort and can understand them like Dr. Casselman can.

Dr. Casselman began his education with a BS in Biology from Binghamton University in Binghamton New York. Next, he attended the Muscular Therapy Institute in Cambridge, Massachusetts, where he obtained a 1200 hour certificate in muscular therapy. Before realizing that he wanted to become a chiropractor, Dr. Casselman worked as a massage therapist. In order to become a chiropractor, Dr. Casselman attended Life Chiropractic College West, located in Hayward, California. He earned many honors during his training and graduated as salutatorian of his class.

As a Highlands Ranch chiropractor, Dr. Casselman is a member of the Colorado Chiropractic Association.
