Testimonials
“DR KOESTER, THROUGH ALL THE YEARS I HAVE KNOWN HIM, HAS ALWAYS BEEN COURTEOUS, KIND, GENTLE, THE BEST!”
-- Phyllis Kortas
“Dr. Koester and his staff have been serving our family for over 20 years now. This is a pretty astonishing statement, being that our family had a huge fear of dentists. My family had no regular dentist.
One day, 20 years ago, and the need for a dentist could no longer be avoided. My husband had a serious tooth ache and had to see a dentist. A friend of mine recommended the name of her dentist. Who at the time was Dr. Koester's partner. Her dentist wasn't available, but Dr. Koester was. We made the appointment.
We have never experienced the most gentle, kind, patient, and understanding dentist until we met Dr. Koester. We went from never seeing a dentist, to seeing Dr. Koester regularly every six months.
My daughter has grown now, and is starting her own family with Dr. Koester. We have passed on Dr. Koester's name on to family, friends and co-workers. There are so many things in life to worry about. Taking care of yourself by going to the dentist on a regular basis shouldn't be one of them. Dr. Koester and his staff can put you fears to rest.
Sincerely”

“While growing up, it seemed like I was always in need of dental work. Nothing I did, nothing I tried, ever allowed me the privilege of going in for a teeth cleaning and hearing those magical words: “No cavities! See you in six months!” What made it worse, was the work done to my mouth always ended in such pain, I was laid up for a day or two afterwards.
Once I became an adult, I entered into a destructive pattern. My fear of oral care was such that I did not go to the dentist until the pain was so bad I had no choice. I thought one thing was certain in life: dentist equaled pain.
In the spring of 1998, it was time to go dentist shopping. Being new in the area, I had no one to ask for references, so I turned to the yellow pages. Judy was the lucky lady who answered my call and I remember every word. The time she took to address my concerns, questions and fears convinced me Dr. Koester was just what I was looking for. In all these years, I have never considered searching out another dentist. From calming my fears to making appointments, Dr. Koester and his entire staff has continually gone beyond my expectations.
For the first time in my life, I can do something I never thought I could do; recommend a dentist! While there is no way I can convey everything I have experienced in this letter, I can guarantee that discomfort, fear and anxiety will become a thing of the past once you allow Dr. Koester and his staff show you how dentistry should be experienced!”
