i saw Dr. Marcus for the first time on 7/1/26 after having terrible experiences at another endodontist in Woodbury. Dr. MARCUS was so reassuring and explained every thing in detail about my upcoming procedure/ a vast difference from the previous dentist. I know I will be in good hands with this wonderful professional!

riley n.

I was so nervous when I found out that I had to have root canal. I was referred to Dr. Marcus. His office staff made me feel at ease from the moment I spoke to them. They are so friendly and accommodating. I could not imagine that this procedure could have been any easier or more convenient. Thank you for making this experience so positive.

I love Dr Ivan!! The staff is so nice and make me feel very comfortable. He makes the whole experience very pleasurable and I’m so glad I am his patient !! He is kind, helpful and encouraging!!

donna f.

Dr Marcus is incredible!! If I ever need a root canal again I will not have any anxiety about having it done again with Dr Marcus. He let me know step by step what he was doing and what I should expect. He said I may have some discomfort later on and told me what to do to relieve the pain if it occurred. It never happened!!!! I highly recommend Dr Marcus- you will be in good hands!

Faith J.

Dr Marcus is the absolute best. I was nervous and he made me feel at ease. Best of all, he made sure the procedure was painless.

Eric J.

I can’t say enough good things about this Dental Office. I came here on a Monday with no appointment needing an emergency Root Canal 🦷. I was taken in by the nice staff and given treatment right away. Dr Ivan Lukachynets was incredibly professional. Thorough, fast, and very knowledgeable. There’s a reason this place has a 5.0 rating with over 1100 reviews. That says something. My daughter was a patient here & now she’s in Dental School. What more can I say.
