A note from Dr. Kennedy,
​
"One of the most important things about my career is building strong relationships with my patients. I've heard from hundreds of patients that had poor experiences with medication and gave up on treatment... "
​
"I have found that when my appointments are not confined to the typical, short 15-minute appointments, and instead have an hour together, that I can carefully listen to my patients and their families and build a solid doctor/patient relationship. This is my practice philosophy for providing meaningful care and its essential for sustaining long-term successful treatment."
My goal is to help provide my patients and families with the tools they need to maximize their potential.
