Whole staff are great. They are very professional are friendly. I have been going to Dr Casey office over 15 years for yearly deep cleaning, fillings and watch out the implants which she installed crowns for me at my very begin visiting (15 years ago). My teeth are maintained very well by Dr Casey. Three implants/crowns were done at my first visiting period. Over 15 years, only few tiny fillings further are needed. Before visiting Dr Casey, my teeth needed three implants/crowns with 15 years younger at that time. Two and half years ago, during yearly dental clean, Dr Casey identified my back bottom teeth yellow staint, it was Dr Casey who first suggested me to visit my GA specialist. I was lazy to make an appointment with GA. She reminded me again half year late. Finally, after I got covid-19 vaccinated in this June, I visited GA and got intensive testing at my stomach and colon, which my dentist Casey suggested. Three out of five polys are very active and dangerous style polys, named as pre-cancer, removed during colonoscopy. It is strongly suggested by my dentist Casey to visit GA, otherwise, I definite lazy/delay to visit GA, the pre-cancer going to develop cancer (one polys already glow to 16mm). Really appreciate Dr Casey and whole staff in her office !

I have been going to Dr. Casey for over 10 years now and I am very happy with the service her and her great staff provide. From flexible times for appointments to a fun happy environment sometimes I forget I’m at a dentist appointment. I especially like Dr. Casey’s sense of humor plus she takes good care of my teeth! I highly recommend her and her great staff to anyone.

Dr. Casey skipped part of her lunch so that she could fill my cavity. She didn't have to do that, but she was amazing!
