I’ve had root canal treatments from three different endodontists, two of them being the main ones in Huntington. I know for sure that Dr. Marcus is by far your best choice. His office is very nice and comfortable and his front desk staff members are very nice. There’s a keurig coffee maker in the waiting room so I always have a nice cup of coffee while I’m waiting. He runs very…

Dr. Marcus patiently waited over an hour for me to get numb and took care of a badly infected tooth that had me in misery for three days. The pain is gone now and I have my tooth. Thanks a million, Dr. Marcus, to you and your staff!

I have been a patient of Rick Marcus for a number of years and have always found him to be outstanding. He works practically without any discomfort with root canals and is always using the latest proven techniques. He is highly skilled and has a perfect touch. Today I had a periodontal cleaning with a new hygienist named Julie and that too was an excellent experience. This is an office that consis…

Dr Marcus and his staff are absolutely amazing. Needed to get my 8 year old daughter in for a broken tooth. They were more then accommodating. They were able to give me an appointment the same day. Dr Marcus made my daughter laugh and made her feel at ease. Absolutely wonderful doctor. The staff from the front desk girls to the MA were amazing. Highly recommend this office.

Dr Marcus and his staff always go the extra mile and provide unparalleled medical care and service. He has been treating me for years and I can’t imagine going anywhere else. He is not only a skilled clinician but the nicest person you’ll ever meet. Would recommend him to all my friends and family.

Could not say enough about how professional both Dr. Marcus and his staff are. I had a pretty painful tooth issue that my normal dentist immediately assessed would need a root canal back in April. I quickly made an appointment with Dr. Marcus. I was treated amazingly by both the staff setting me up, the assistant in the room helping Dr . Marcus and most importantly, the skill and compassion from D…

Dr. Marcus is the best doctor I have ever visited hands down. He was so attentive and helped me to locate the pain that no other dentist could. I tell all my friends and family to go to him – 100% the best!

Dr. Marcus made my daughter’s root canal experience one that she will remember in a positive way. In fact, she laughed and smiled through the experience instead of having the fear that she usually has. Not only was Dr. Marcus amazing but his staff was as well. They spent an extra hour helping me through an insurance issue! I highly recommend using Dr. Marcus for your child or yourself!!

Dr. Marcus is amazing! When I needed emergency root canal over the Christmas holiday, he not only made sure to get me on the calendar immediately, but treated me as if I was one of his own patients. I live in Philadelphia and was told by my local dentist that I was SOL as they were closed for the holiday (without coverage). I’d tried calling several other oral surgeons, but none of them woul…

This is a wonderful office. Dr Marcus got to the root (just a small pun intended!) of two problems in the summer of 2015. He is an amazing endodontist and did everything he could to make me a pain free person.
