  • I came into the office with a problem and as usual, it was handled very professionally by the entire staff. Dr Armento is always very calming and thorough. He explained the problem and gave me the solution. I will have a follow up appointment. My family and myself have been going to the Doctor for at least the last 11 years. We are very satisfied with the professionalism and efficiency of the Doctor and his staff.
