Roots canals as are no fun. I had a very painful infection in December and Dr. Herceg saw me immediately, went right to work on doing whatever it took to ease the pain, then performed a root canal that was, if not entirely painless, at least took me out of the misery I’d been in. Three months later, its completely healed. I am so grateful to her and her staff for their courteous, kind way in treating me. I especially appreciated Dr. Herceg’s warm, comforting nature and her apologies when she had to hurt me! I recommend her highly.


I was in excruciating pain upon my arrival to the office. The staff was extremely polite and caring, and got me in right away to see dr. Rosenthal. He was so easy going ,and the best part PAINLESS!!!! I totally recommend this office. Thanks again Dr. Rosenthal, your the best.

I was not thrilled about having a root canal but Dr Rosenthal and his staff made it as pleasant an experience as it could be. I’m happy with the result and pain free!

Excellent! I was visiting from out of town and Dr. Herceg and her staff were more than accommodating. They were helpful and did an excellent job in taking care of me, not to mention that Dr. Herceg skipped her break to see me and perform a root canal that would of taken few visits to complete. Thank you!! I am so thankful.

Such a genuinely caring demeanor and very knowledgable and able to explain procedure very clearl. In addition, I can’t believe how much less pain I had than with past like procedures elsewhere.
