  • I've been going to Alan since he opened the practice in Denville, and have been extremely satisfied with his work in preventing periodontal disease. I'm also appreciative of how well he coordinates with my regular dentist. Highly recommended.

  • Another great cleaning and visit at AR Perio.
    Cleaning was done well and on time. Office was clean and comfy! Everyone was happy and friendly! Will be back in a few months!

  • I have 6 teeth compromised from orthodontia half a century ago. Dr Rothstein has kept them going longer than I would’ve thought humanly possible. When the time for implants arrives I wouldn’t think of letting anyone else do them. And the hygienists are wonderful. I would go every day and have them clean my teeth if I could!

  • Dr. Rothstein is extremely knowledgeable and listens well. He is the utmost professional as well as his staff. Impressive is an understatement and my dental work is on point. I recommend his office with super high regards!!!

  • I have been a patient of Dr Rothstein for many years now and always have received excellent care from him and his whole staff. If you're nice to Diane at the front desk she'll even email you an occasional joke or two. What more can you ask for? 😁

  • Been going there for years. I have Lynn as my hygienist and she is fantastic. Dr. Rothstein is a great doctor and very personable. Never a wait there. My kid loves the salt water fishtank in the waiting room
