About Me

“I went into medicine to provide care and compassion to those who are most in need. I’ve learned that the job of a physician is to see the patient as a whole and as a part of the larger community and social network. We do not only treat the person, but we also indirectly treat their families, their friends, and their communities. I’ve learned that my job as a physician is often to teach them to educate my patients and to provide a caring environment that we will allow them to heal. The Latin root of the word doctor means teacher and I work my hardest to integrate educating my patients into my practice. My focus in medicine has always been patient centered. An integral part of my education throughout residency and fellowship has been Mayo Clinic motto, “the needs of the patient come first”. I live by this motto on a daily basis and integrate this philosophy into all of my patient experience.”
