When I joined this practice about 2 years ago, I thought I found the office I'd always dreamed of…read more. one that treats you like family and puts care and passion into what they do. Not sure why, but I've had some scheduling problems with Andrea, the front desk lady. When I was pregnant we pushed my x rays until June- my baby was due in May. A month later I got a reminder phone call about my past due x days. No... I was pregnant and we rescheduled. Fast forward. 2 hours before my most recent visit I get a call saying I owed a few hundred dollars for white fillings. That their office still offers silver fillings. I have my moral viewpoints on silver fillings and i refuse! Why are you telling me two hours before my a lot, when I've gotten a sitter for my baby, taken off work and moved my schedule to be available when scheduled! I then called my dental insurance and it's covered. What the heck? I asked to speak to Dr. Zauderer (with my sister on the phone as well) and i got YELLED at and told my opinions were - and I quote "bologna ". Well, I didn't ask you to scrutinize, raise your voice, argue and judge me for something that's important to me. Your practice already knows I refuse fluoride, why can't you respect my feelings and lifestyle choices? Needless to say, I've left this practice and won't return. It's a shame because I really enjoyed Zusana and Amanda and they work hard! And seriously, what dentist office still offers silver fillings?

CONSUMERS BEWARE! The procedure and Doctor were…read moreexceptional! would be rated 5 stars. The billing department is the opposite! If you go here make sure you "Request an Estimate"(From Christine, Manager). Apparently, the amount they tell you is a guess unless you request is to be official! Never heard of this before in the years of going to dentists. Watch out for the "Balance Past Due" bill for the amount that was not covered. I received this Bill with a colorful past due sticker not even 30 days after the procedure! very disturbing after the amount of Money that is already paid, to receive a bill! This is a very sad ending to a Stellar experience. Tom

Went in for an unscheduled visit, and they solved the issue with a reasonable price. The reason…read morefor only 4 stars this time is the upsell is a bit intimidating. The first visit I was there for just a cleaning, and they recommended a cap, which I was surprised. I didn't need, so I declined. There was no pressure to purchase, but about 4-5 weeks later someone called to schedule the cap appointment. On my second visit I went in for tooth sensitivity, which they solved, but then wanted to upsell an expensive mouth guard, which I politely declined. I'll continue with my regular cleanings for now, and will gauge after each visit if it is worth having to sit through a sales presentation each time I go for a cleaning.
