Philosophy of Care

“I live by the golden rule that I treat patients like I would treat my family members or treat myself. I have found that this simple rule has guided me along my journey to develop an empathetic and patient-centered practice.

“Patients have better outcomes when they are informed and educated. For this reason, I’m very much about communication and transparency. An educated patient is generally a healthy patient. I also ask patients to take ownership of their care and urge them to live a healthy lifestyle.

“Empathy and taking the time to listen are a big part of my practice. The history and the story that one gets by listening to the patient are as valuable as any objective testing that we do. Above all, I want each of my patients to feel that they are my only patient.”
