    Margaret is such a great pcp, and is an asset to this practice. We will be moving to Delaware in about 10 months and I hate the thought of not having her as my pcp. Might have to still make the trip to see her!

    The only complaint I have is it's very hard to get through on the phone lines. You have to call six, eight, nine times at five, 10 minute intervals before somebody picks up the phone. So I don't know if they need to have more people answer the phone or what, but it's very hard to get through to speak to somebody.

    Every staff member- All inclusive are courteous, caring and most accommodating in every way. These doctors and staff are so caring kind and competent beyond many others I have had. There is a family feeling as soon as you walk in the door. My husband and I wouldn't trade this practice with our lives and health for any reason!

    Been seeing Margaret for a couple of years now, and do not wish to go anywhere else. I moved to Baltimore county at the end of last year, but am willing to drive the "almost" hour to come to this practice. Highly recommend!

    We are fairly new to the Westminster area and it was difficult finding a physician that we were comfortable with so we kept driving back over the Bay Bridge to the Eastern Shore and the physicians we had been seeing for many years. Prior to moving here we asked the physicians we had been with for several years for a referral but they were not familiar with anyone in this area. So, we tried different doctors looking for someone we would be comfortable with. It took a bit of time, we kept looking and finally, finally we went to Dr. Vento's office. My husband sees Dr. Vento and he is very satisfied with every visit. I see Margaret Dermer and I am soooo happy with the care she gives me. She has always responded to my concerns, gives me excellent advice and I am confident that she is dedicated to her chosen career. I hope I never have to search for a new physician again.
