Ravi Kumar, MD


Dr. Kumar is one of the most experienced clinicians with the Family Medicine Residency program. Over the last 45 years he has been a committed and enthusiastic teacher for many physicians. He starts his days full of energy. You can see him participating in didactic sessions, precepting at the Family Medicine Center or seeing patients at his other practice site. When asked about his pet peeves his response was, “Negative thoughts, procrastinators and lazy bums”. Kindness and a spiritual nature are just a few of his qualities. He loves medicine and defines himself as “one who seeks finds”. An avid reader over his lifetime, he keeps himself up to date with regards to practicing evidence-based medicine. His goals are “to publish” or jokingly “perish”. His best times are when he is relaxing at home with friends and family.

Dr. Tariq is a graduate of our Family Medicine Residency program. She is an intelligent and hard-working physician with a twist of humor. She works as an attending on the inpatient service, precepts in the Family Medicine center, and oversees the Medical Students who rotate on Family Medicine services. She has two young children and is devoted to her family. She enjoys traveling and catching up with her family members who live overseas.

When asked about her hidden talents, her response was very fast and adamant: “I am a good cook”. Her favorite place is Niagara Falls.

Her pet peeves are: People who don't respect personal space, people who honk their car horn for no obvious reason, and inefficiency.
