"Dr. Tom O’Hollearn is more than a chiropractor—he is like a friend. I’ve been in his care for 17 years. His techniques have alleviated me from a lot of pain over the years caused sports injuries, motherhood/posture injuries and silly things sleeping wrong. His staff is friendly and never miss a beat. Very highly recommended."

"I have been going to see Dr Tom for over 10 years. He takes time to get to know you and remembers our conversations at the next visit. I feel great when I leave there. Front desk employees are very welcoming. They don't try to sell you on packages either."
