I've been going to Dr. Bishop's office since my first appointment as a child and for almost 30 years now. Nothing has changed other than relocating from Greenville Ave to the beautiful new building off US 75. The staff and dental hygienists are exceptional. Can't say I've ever had a poor/painful cleaning. It doesn't matter if you see Dr. Bishop, Kim, or Koelker. They are all excellent, professional, and make you feel comfortable to visit the dentist. Lastly, they are always very informative and guide you towards treatments they recommend. They don't push you or make you feel obligated to move forward with a procedure in means to make money. Visit The Dentist of Allen, and don't worry about switching dentists ever again.
Dr. Koelker & Dental Higenist Laura are prompt, efficient and caring. You are never rushed in & out. I would recommend them to anyone looking for great dental care.
Friendly and knowledgeable staff, it’s an easy process from start to finish. The dental hygienists are awesome, and do a great job. I have seen both dentists there and I would recommend them both, Dr. Koelker and Dr. Kim. The front office staff does a lot to make sure I am able to schedule and change appointments if needed, and have even reached out after hours via text to double check my insurance several nights before my appointment, to see if I needed to switch to private pay to make sure I wasn’t potentially billed beyond my limits. That’s great service.
The Dentist of Allen is a top notch! Everyone is amazing and Dr. Koelker is fantastic along with Christina and Patsy! They are a team unlike any other. Five stars is not enough!!!
