The doctor listened to symptoms I had been experiencing for several months and ordered additional tests to determine if there was a blockage. He also informed me to seek medical assistance whenever I experience these symptoms since they could indicate a potential heart attack or stroke. The nurse and receptionist were very thorough and accommodating when dealing with my medical history and scheduling the tests ordered by the doctor.

Appreciated time with young intern first; Dr. Buffer was welcoming, thoroughly explored my year on the meds, asking pertinent questions, listening carefully, urging me to keep track of my blood pressure and any change in symptoms. Only see him yearly but able to keep in touch throughout year.
