    Extremely pleased following first consult visit with Dr. Matthew Grossman. Productive and informative discussion. For background, I requested a consult with Dr. Grossman following self-directed online research. Was assisted in making the appointment by my colleagues at AHS Executive Health (who are an invaluable continuing resource to me). Dr. Grossman met my highest expectations. I have high confidence in Dr. Grossman and look forward to working with him for my upcoming procedure and follow-up consultations.

    From first phone call to make appt., arriving in office, staff was courteous and pleasant for check-in. Asst. was a very relaxing person and personable. Dr.'s PA was thorough and pleasant. Dr. walks in with a smile, shakes hands with both hands and puts you at ease by the time he has finished explaining in detail the plan to take. Spoke so you would understand, asked if you had any questions and answered in detail. Overall one of the better experiences visiting a doctor.
