Patient Reviews

"Dr. Koelker & Patsy are the best!! I am confident & comfortable with Dr. Koelker & his team. The whole office works well together and as a patient you are informed of treatment options & treatment cost. Will continue to come here for dental care."

"The Dentist of Allen - Hygienist Emily and Doctor Koelker and the front desk staff made my visit another wonderful "The Dentist of Allen" experience. I highly recommend this organization."

"If you’re looking for a dentist, this is the place! Dr. Koelker is an incredible doctor. Every time I’ve had anything done, he is very thorough, he communicates well, and his work is amazing. I’ve had many compliments on my teeth and smile for years now. And I recently had a cosmetic procedure that I’ve been completely satisfied with. I decided to get caps (I experienced a chipped tooth) and I must say that I was a little concerned that it was going to be painful. I was shocked how smooth it went. He made it look so easy and I had little to no discomfort at all. I can’t stop smiling because my teeth look fantastic, you can’t even tell the difference where the cap is because it perfectly blends. He and his staff have done a marvelous job. I’ve already been asked by neighbors and friends where I had them done. I can’t stop raving how happy I’m with Dr. Koelker’s work."

I use Laura for my cleanings and I love visiting with her. She’s so sweet and fun. And Patsy works with Dr. Koelker and she’s great. She’s very good at her job and just wonderful. She definitely knows all about shades of whitening, as she could be an artist.I highly recommend this practice and Dr. Koelker. The staff has always been very friendly and the girls up front have helped work around my schedule and help me with anything I need. They are awesome. They also have a dental plan through their office that saved me quite a lot of money. I was able to save 20% off procedures. I recommend asking them about their plan when calling for an appointment"

"I had my first visit and I'm happy that I decided to go to this office. Cynthia was great and explained every step she was doing to x-ray and clean my teeth. Dr. Koelker is very thorough and again explained what was going on with my teeth so that I could understand. I'm happy to go back. Who ever says, I like my dentist? I do!!"

"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."

"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."

"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."
