  • "The very first time I saw David Loaiza I was impressed that I had one treatment and then he gave me some stretching exercises to do at home to complete my recovery. Over the years he has been effective at addressing a variety of injuries and aches quickly and conservatively. He is knowledgeable, insightful and warm. I recommend him to many friends and colleagues. He is a very good chiropractor."
