I always feel comfortable with Margaret Dermer. She is thorough and always answers my questions. I never leave feeling unsatisfied with my visit.

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 pa was thorough explaining all options.

I do not appreciate being asked my gender preference...which is on Lifebridge not the doctor. If I'm born as a woman I am a woman. This gender business is absolute hogwash

Margaret is great.

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.

Margaret is always kind and caring. She listens, asks good questions, then works with my daughter to develop a plan. I always appreciate her honesty and guidance.

The new location isn't ideal, but my provider is awesome. Everyone I dealt with is great. I'll miss the convenience of having a lab on sight.
- 5 out of 5 starsReviewed on 9/23/2025
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!

The folks at the front desk need to be a bit welcoming. They continue to talk while patients are waiting- about things not related to work issues.
- 5 out of 5 starsReviewed on 9/17/2025
Margaret Dermer is so kind so knowledgeable about my medical needs! Her bedside manner is absolutely the best! I can't say enough good things about her! I'm so satisfied with her being my PA! Thank you

This was my first visit with Margaret Dermer. I found her to be knowledgeable, thorough, professional, and most importantly to me, patient and pleasant. I would definitely like to see Margaret again when I need medical care.

My previous doctor retired and this was my first visit. The front desk was helpful and friendly. The nurse confirmed my medications and history. Everyone was phenomenal. I am so glad I am seeing Margaret now!

Margaret is the best!

I like responding to this text 10 times better than a phone call!! That is annoying.
- 5 out of 5 starsReviewed on 7/19/2025
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.

I was impressed with her.

I am terrified of going to see doctors. I avoid it at all costs. Margaret Dermer was just about the nicest, kindest, most wonderful provider you could ever ask for. I was almost sick driving to the appointment and when I left, I felt like a weight had been lifted off of my shoulders. I wish every person in the medical field was as wonderful as she is

The front office staff has always been unfriendly and inattentive both in person and over the phone. The only reason I continue with that office is because Margaret Dermer is great.

Margaret is very personable and explains things well. She takes time to make sure all your questions are answered.

Margaret is very caring, she takes the time to listen to me. She takes the time to go over my test results and she always answer any questions I might have. Margaret Dermer is very caring. I would recommend her to anyone who needs medical attention.
- 5 out of 5 starsReviewed on 6/19/2025
Dr. Dermer really cares about me as a patient and a person. That in itself is spectacular for someone that is 75 years old. She makes me feel good and well cared for. I cannot compliment the Entire staff enough! They are all above and beyond in all aspects of medical care.

Not always a pleasure to go to Doctors but your folks here make it a pleasure by answering questions and always give the best advise for your care and are the kindest and most gentle people I've ever experienced in a medical office.
