Had my teeth clean by Geraldine. Have never had a bad visit with her.
Staff is always professional and tends to the needs of the patient.
I’m not easily impressed, but this time I was impressed, Started on time (maybe a few minutes early) Staff was cordial, the assistant was knowledgeable, and the dentist was awesome. This was my second visit.
I’m not a big fan of going to the dentist, but I always end up having a good experience. My dentist makes it very relaxing and throughly explains the process before hand in a reassuring manner.

So glad I found Dr. Rothman – I was deadly afraid of dental treatment but not anymore. Had 2 root canals done and it was nearly painless. Great staff as well – always felt very well taken care of
Great cleaning with a friendly environment.
Had an extremely severe toothache and they fit me in for an emergency root canal immediately. All the staff members are extremely friendly and Dr. Rothman was excellent.
First visit, got everything done, even squeezed me in with the dentist right after my appointment!
Professional, thorough and thoughtful.
Great service and so pleasant! I was in and out quickly and didn’t feel anything.
I had an excellent experience with Dr. Rothman and my Invisalign treatment. Also, Geraldine provided me with a great test cleaning!
I love the service they are very very compassionate about the patients that they provide service for I will recommend anyone to come here.
Great experience! What I have become accustom to. Extremely professional and knowledge staff.
I switched dentist and came to Longwharf dental Group by way of recommendation from Sarah who sits at the front desk who’s so bubbly. Super friendly staff and to just say that they make you feel comfortable is an understatement. So happy to say that this is my new home for all my dental needs! Looking for a good dentist?….Try them, you won’t regret it!
I’ve been a patient of this office for a many years and have always been satisfied. The staff, my doctor, Dr. Rothman, are all fantastic! They are on time, honest and they do not try and fix anything that isn’t broken.
Wonderful staff. My dentist is patient, precise and detail oriented when it comes to my procedures. I’ve never had a bad visit.
I absolutely love the staff. They make you feel at home and will answer any questions or concerns you may have.

I love Long Wharf Dental! I highly recommend it to anyone looking for dental care. The dentists, hygienists, office staff are all great.
Long Wharf Dental is a great office! I’ve been with them since I was a kid and won’t go anywhere else. Everyone in the practice from Dr. Rothman, Lorena, and Nela, to Sarah and Andrea is amazing. It’s the only dental office I trust for my kids and I!
Lorena was my dentist that cleaned my teeth. She is always so kind and very thorough. I never feel nervous.
Great practice. Never had to wait for long and my dental hygienist was the best one I’ve met.
Great visit. Was seen immediately. Wonderful hygenist.
Lorena is the best, I can’t say enough about her. She takes pride in her work and shows that she really cares about me. I have been going here for twenty plus years and would not change a thing…
Great dentists, wonderful staff and I always recommend my family and friends to choose Long Wharf Dental for all their dental needs!

Very good experience very good staff will be continuing to get my dental work there and my family
This practice has been truly wonderful. My husband had a bad accident resulting in very challenging dental treatment. Dr. Lerman needed to coordinate with the hospital and several other doctors and surgeons. He and the entire entire staff have been kind, supportive, and very effective, despite various setbacks. We can’t thank them all enough.
I have been very please with the work that has been done to restore my dental to a better health condition. The Drs. and staff have been very helpful and my service has been very good!
My experience was great. Everyone is professional yet friendly! They are all very caring for my well being.
Doctor Lerman is by far the most gentle, professional and personable dentist I have encountered through the years. I always arrive with a sense of confidence that everything will run smoothly. And I never leave disappointed.
I called and was seen the same day. They are so amazing and they take so good care of us as patients. Thank you Long Wharf Dental!!!
Every experience I have had in the office has been very positive. The staff is super friendly and they go out of their way to make sure you’re comfortable.
Dr. Lerman is the best. I had to have a crown placed this month and at each step of the process he was attentive to my questions and explained every part of the procedures. As a slightly anxious patient this helped tremendously.
I was very please with the experience. Despite the fact that the procedure needed to be long and uncomfortable, I found the Dr. skillful and confident which gave me a lot of security. He explained step by step and make sure that I was ok at every moment. The dental assistant was gentle, and ready to assist the Dentist and myself in any need. I will recommend this Dental Office to others.
Excellent! I’m very pleased with this dental group. Everyone is friendly including the dentist. He tells you what he’s doing every step of the way. I’ve had very good experiences and would recommend it.
Quick, painless wisdom teeth extraction. Very professional and caring dentist made me feel comfortable and at ease throughout the process. Highly recommend Dr. Lerman!
This is hands down the most efficient staff, professional dentistry and best overall experience I’ve ever had at the dentist.
My experience has great for my first visit. No long wait. The dental assistants have been very nice and informative. The dentist came in and was pleasant and made me feel comfortable. I don’t like dentists offices but I feel comfortable as a little more at ease here.
I drive a long distance to see Dr. Lerman. He’s the best! Also have been coming here for over 25 years. I would definitely recommend anybody needing Dental Care to come here.
Going to the dentist most be the most terrifying thing known to mankind, but at Long Wharf Dental they make you feel at home and comfortable. I had not been to the dentist in 8 years prior to my visit but now I have been to the dentist office every week to get things done because I trust them!
Dr. Lerman has been patient, friendly, and understanding during all of my visits. The entire staff is always warm and inviting. They are willing to work with you if you have a last minute emergency come up and you need to reschedule. I can’t imagine going to any other dentist!
Friendly, warm and welcoming atmosphere. I’ve recommended their services to family and friends and will continue recommend their service in the future.
I’m most impressed with the fact that EVERY appointment I’ve had in the some 5 years I’ve been a patient, I have never had to wait more than 2 minutes in the waiting room. That is very rare in the healthcare field and is very frustrating to me (I can wait up to an hour in the waiting room and then another 20 minutes in the exam room at my PCP’s office). Your practice is a v…
