    I have been seeing Dr Penberthy for 10 years now and under her care I have seen a marked improvement in the control of my diabetes, blood pressure and cholesterol. My weight is stable and on a downward trend. I recently moved to Lewes DE and my drive to Dr Penberthy is now ~2 hours one way. Yet I plan to continue to see Dr Penberthy because of the high quality of treatment I receive and the care and attention she provides. The office staff is wonderful to work with and effectively complement Dr Penberthy's patient care.

    I have not always had good experiences in hospital systems. Doctors have often felt dismissive, rushed, unknowledgeable or unhelpful. Dr. Penberthy was the opposite of that. She is thorough, thoughtful and helpful. I am glad a resident was in the room so he could learn from a doctor who knows how to handle a patient.

    It took me a year to find a doctor. I found one that listens to me and my needs and listens to my concerns and then will stand for when I do something that's not beneficial to myself to make it correct. So I love Dr. Penberthy. I love her. She's someone I can tell everything to. She's someone that listens and responds to all of my needs and that's definitely important to me considering I've only had four doctors in my whole life and the only reason I had four was due to the fact that my childhood one retired. My teenage one retired and chem care wasn't good enough so I chose Dr. Penberthy and I made the right choice.
