Background from greenwichprivatemedicine.com.

Dr. Chetan Vaid, MD, is a board-certified internist at Greenwich Private Medicine in Cos Cob, Connecticut. He earned his medical degree at Rutgers New Jersey Medical School and trained in internal medicine at Thomas Jefferson University Hospital in Philadelphia, where, according to his practice website, he was named Most Outstanding Resident.

He has been licensed to practice medicine in Connecticut since 1998. His practice website says he spent 14 years in a large multi-specialty group practice in Greenwich, and that during that time he was elected Treasurer of the Greenwich Hospital Medical Staff, served on the Greenwich Hospital Executive Board and served as Vice-President of the Greenwich Physician's Association.

He has privileges at Greenwich Hospital, which lists him in its physician directory. His focus is adult primary care: prevention, high blood pressure, diabetes and cholesterol, evaluating new symptoms, and coordinating care with specialists. He sees patients age 16 and older.

Time to talk. On the podcast he said he wants patients to feel that he listened to them and isn't rushing them, with time to talk and express themselves. As he put it, most patients come in with "not just one issue, several issues."

Know your numbers. He said patients should know their blood pressure, sugars and cholesterol, and that "one number never makes a diagnosis." He looks at readings over time, and if a reading is high in the office he may ask you to check it at home.

Pulling specialists' advice together. He calls it advocacy: helping patients who see several specialists understand what each one is trying to accomplish, then following through on one plan.

Summary written by Top Providers from his podcast interview and his practice website, the Connecticut license lookup, the Greenwich Hospital physician directory and the ABMS Certification Matters lookup.

In his words

Verbatim from his podcast interview.

Checkup numbers
One number never makes a diagnosis. One number never kind of locks you into a problem.

What to look for in a doctor
I want to make sure when a patient comes in, they kind of feel like I listened to them and that I'm not rushing them and that they have time to kind of talk and express themselves.

When your doctor has time
Most patients come in with not just one issue, several issues.

What to look for in a primary care doctor

What gets missed in a short visit

Why you can't feel high blood pressure

Shorts0:36

Seeing several specialists? Who puts it together

Fairfield County ticks: where to check your body
