When Dr. Colt was young, a family friend who taught him how to fly became his mentor. His son was a Gonstead chiropractor in Pensacola, Florida. Dr. Colt traveled south to shadow the chiropractor and see what it was all about. Seeing the fun, lively and healing atmosphere made Dr. Colt realize that he, too, wanted to be a chiropractor.
“If I can help people to avoid more invasive routes like drugs and surgery, I want to take care of them. You can get your problem fixed the right way by addressing the root cause.”
To complete his undergraduate education, Dr. Travis Colt DeWitt attended the University of Iowa. He then moved onto the renowned Palmer College of Chiropractic in Davenport, Iowa to earn a Doctor of Chiropractic.
When he isn’t in the office, Dr. Colt loves to spend time with his wife Dr. Nicole, daughter Scarlet, and son Beau. They like to be outdoors and often go to their cabin, fishing on the nearby river and hanging out on the sandbar. Learn more about Chiropractic Care here!



With an early interest in the human body, Dr. Nicole knew she wanted to go into the health field. She was very active in sports as a kid and experienced many of the aches and pains that come with that. When she was 16 years old, a chiropractor kept her off the surgeon’s table by treating a shoulder injury non-invasively. It opened her eyes and showed her that you could treat the body naturally without the need of drugs and surgery.
“Chiropractic can address so many things that people would go to the medical doctor for. It’s the natural approach.”
Dr. Nicole attended the prestigious Palmer College of Chiropractic in Davenport, Iowa. There, she joined the Gonstead Club, attended Gonstead seminars, and learned from teachers influential in the field. It’s a chiropractic technique that just makes the most sense.
In her spare time, Dr. Nicole loves being a mom to Scarlet and Beau and hanging out as a family with her husband, Dr. Colt. They like to spend time outdoors – gardening, exploring the woods, or spending time at the river. They also have three dogs and one cat at home that keep them busy when they aren’t in the office.
