My principal role as a treating physician is to provide the patient with accurate information about their diagnosis and treatment options. Once the patient is well-informed, we can work together to accomplish a desired goal. I enjoy helping others feel well so that they can live healthy, productive lives with great quality. When I am not working, I enjoy spending time with my wife and tireless two boys. I love music, traveling to exotic destinations and playing soccer.

Dr. Guillinta is such a kind soul and very compassionate and understanding. He explains his plan of care and while he encourages his patients to eat well, stay active and take care of ourselves, he also recognizes the challenges to always do the right thing. And shares not to beat ourselves up, explaining we should focus on doing things in moderation to allow us the occasional misstep.
