Patient Testimonials

Thank you, Dr. Reff for being so professional and so helpful to me during the root canal.  You were very compassionate.  It was especially comforting because you talked to me thoughtout the procedure, telling me what to expect, etc.  Thank you so much!


I write to acknowledge that my experience of having my first root canal was a positive one.  Your kind gentle manner put me immediately at ease and the entire procedure was painless.  I also want to acknowledge your assistant, Jenny, for her kindness.  You are an awesome team!  Many thanks.


Thank you, Dr.Reff, for your professionalism, convenience, & prompt attention to my dental emergency. The kind & courteous staff was an added bonus! I appreciate your help!
