I have been with Lighthouse for more than 35+ years. Dr. Samuels stands by his work and patient satisfaction and comfort is his primary concern. The office extends itself to accommodate your busy schedule which is reflective in its posted office hours. It is always a pleasant and friendly experience to visit his practice. Patty Ulatowski

Friendly staff, very professional, courteous and caring. We are a family of 4 and are all customers there. While doing a cleaning this past November, Courtney decided to ask D.M.D Joy Cocchiola to double check a lump underneath my jaw. That lump turned out to be the beginning of throat cancer (never smoke in my life). Without that early detection, God knows what would have happen. I’m under…

No staff has ever treated me better. Dr. Joy Kurzner and Maggie exceed my expectations at every visit, from their knowledge to their genuine interest in my well-being, in dentistry and my daily life. The facility besides is spotless, and never had I before heard of or thought to use sunglasses during procedures, nor that I might select a TV channel to watch meanwhile.

TRULY AMAZING! My whole life I struggled with the insecurity of my smile. It was really bad. I was absolutely shocked at how fast my teeth started moving.

Haronne C.
Dr. Kurzner is awesome , I have been going to her for years , never any discomfort at all and quick appointments!! Highly recommend!
Nancy T.
Irena always performs excellent workmanship/cleaning on my teeth. She wants the client to walk away with a smile which she has high expectation of self conscientiousness. It is inspiring to look in the mirror and know a manicure effort was performed. I guess I will have to wait for my next appointment. Too bad she does an excellent job now I have to wait longer until my next appointment.
John P.
Hygienist was awesome, down to earth while wholly professional. Scheduled my next appointment with her again because she’s great.

I came to Lighthouse Dental because I was unhappy with Aspen Dental whom I had been using. Dr. Samuels is extremely thorough and even though I really disliked going to the dentist the staff there is wonderful and makes my visits easy and comfortable.
