Join us in welcoming Catrice to The Dentist of Allen family!

She has joined our dynamic team and will be our Hygiene Coordinator. We are so grateful to have her.

Catrice is married with a teenage daughter “KK” and has been in dentistry for 5 years. Catrice loves people and taking care of our patients is her priority!

She works with our hygienists to keep our patients on a recommended dental care schedule! The routine visits with our hygienists means keeping our patients dental health in check and she is all about healthy mouths!

It is her goal to make sure every patient we see leaves with a return appointment to keep them from veering off of their dental care timeline.

Her nephew “KJ” is her world, he is the happiest toddler and spending time with him is such a joy.

Catrice and her daughter recently got out of braces together – that was a FUN journey. Catrice and her family enjoy dinners out that always end with her favorite dessert ~ cheesecake!

Join us in welcoming Catrice below!


Meet Amie! She is the Manager of our brand new Pediatric Department, look for "The Children’s Dentist of Allen" coming soon!!

Amie has been in pediatrics for over 7 years and loves to help our younger patients have the best experience possible so they have a life long love for dental health and a great relationship with their dentist.

Amie has two “mostly grown” children of her own, two fur-children and in her free time she and her husband like to travel, finding adventures near and far.





The most recent December issue of the Texas Monthly Magazine has listed "Super Dentists" throughout the state in a directory fashion. Since David R Bishop DDS is the representative for, we have been chosen again and are listed in their directory under my name but we have never invested in an ad for their issues.

We, at, would like to identify a point that is extremely clear to us and needs to be said.

Our patients are the absolute best patients in the state of Texas.

That doesn't imply there are perfect teeth in every mouth. It implies our patients laugh and smile with us when we work.

We never have to wait on a patient for their appointment and they never wait on us. For those of you reading this that have been late to an appointment, remember that you always called us and told us what the blasted traffic is like on Hwy 75. We have cancellations at the last minute
and I remember when I had to cancel patients when I left to meet my wife delivering my children at the hospital. We understand the need for compassion in such an uncomfortable service. It is amazing the unsolicited apologies that pull on our heartstrings; because we know.

We have discussions about costs like I had for my $85,000 knee when I broke it skiing. Hey, we're all human and we're all looking for equitable value and certainly extremely skilled hands. All of our patients are second to none from our point of view. We scour the earth delivering the latest techniques and materials for everything we do because that's what we do and you would do it for us.

I've recently added new employees to my staff and their universal comment is how wonderful the patients are at our office, much different from where they came. That is a huge reason for my staff's long tenure working here.

We want to thank every one of our patients for being the absolute
best and extend an invitation to anyone that would like to join us at; everyone is welcome.

Paula McDaniel is originally from Maryland/Washington D.C. area. She graduated in 2001 from Brigham Young University w/ a degree in History (which she now uses to be very good @ trivial pursuit and entertain her patients). After 8 years as a dental assistant she decided to further her education in dental hygiene and graduated in 2010 from Collin County Community College. She is certified in CPR, OSHA and Laser Treatments. She has the cutest nephew ever and 2 fantastic dogs named Remington and Colt (black mouth cur dogs). In her spare time she enjoys running, boxing, crochet, photography, baking and attending concerts.

We’re so excited to have Paula as part of our dynamic and hygiene department! If you haven’t had a cleaning with her yet, request her next time you schedule an appointment!



Hey y’all!

My name is Taylor and I graduated from Dental Hygiene school in Amarillo, Tx in May of 2018.

I grew up in small town, Snyder, Texas, but the city was calling my name! I have 4 sisters and 2 pups, Theo and Stella. In my spare time I enjoy working out, reading, being outdoors in the sunshine and watching sports!

For as long as I can remember, I have been fascinated with the dental office and have always known hygiene was what I wanted to do when I grew up! Being a hygienist gives me the opportunity to serve others by helping them to be happy with the smile they see in the mirror, to create lasting relationships with patients, to educate patients, and to always continue learning.

So far, I’ve thoroughly enjoyed my time at The Dentist of Allen and I look forward to being a part of this team for a while!

Happy 5 Years Dr. Koelker!


We are so fortunate to have Dr. Koelker as part of our team of doctors. We can’t believe he has already been #makingallensmile for 5 years. Have you met Dr. Koelker?

Dr. Koelker’s patients appreciate his profound interest in their health and his constant attention to the latest advancements in dental care. His specialized skills help him successfully execute complex and detailed dental procedures. Dr. Koelker is an outstanding clinician, but he’s also committed to providing comfortable and comprehensive care centered around the patient.

An Allen native, Dr. Koelker grew up in Allen and graduated from Allen High School in 2003. Go Eagles! He continued his education by attending Texas Tech University where he received his Bachelor of Arts in Chemistry and excelled, graduating with honors. Dr. Koelker furthered his education by receiving his Doctorate of Dental Surgery from the prestigious University of Texas Health Science Center in San Antonio in 2012 and graduated with honors as well.


After graduation, due to his excellence and passion, he was chosen for an Advanced Education in General Dentistry residency where he received specialized skills in IV sedation, implant placement, and wisdom teeth removal. Dr. Koelker then moved back to his hometown and joined Dr. Bishop and Dr. Kim at The Dentist of Allen in 2013.

He feels blessed to be practicing dentistry in his hometown and is devoted to providing the best quality dental care for his patients. Past patients have said that Dr. Koelker takes the time to answer your questions and thoroughly explain your treatment options!

Do you have a question for Dr. Koelker?

Paul is really hesitant to go to the dentist because they always

find something wrong with his teeth and he knows he'll have to come

back and have work done and he isn't in the mood to even pay his

portion after insurance. If you can relate to this, you're not alone.


   Dr. Smile is walking into the room after Paul has had his teeth

cleaned and knows Paul has anxiety about work he has had done in the

past so the pressure is on the dentist to "not" find anything. Reality

is, he needs to be effective in deciding on issues that require

intervention or it may progress until either more work is necessary,

it could start hurting, or the tooth could be lost. Stress on both

sides.  Skill and diplomacy is paramount from the dentist on these

matters and it becomes difficult to choose the right words and deliver

professionally. is unbridled by corporate pressure to provide

income to a third party owner usually in a different state. I

frequently hear the notion that dental work is being done that doesn't

need to be done by dentists and the first defense a patient has to

protect himself from that notion is to establish a dental relationship

with a dental team that is not owned by a third party we call corporate.


There are more than 18 corporate dental practices in Allen
some disguised as private practices. PPO dental insurance unlike
medical insurance is a corporate product.


    The entire team at is focused on educating

every patient on why any procedure needs to be done. Xrays are not

difficult to understand when a skilled professional demonstrates and

points out issues on them. Models help with advanced procedures like

implants and cameras can illustrate things that are almost impossible

for the patient to see in the back of their mouth. A sequence of

photos taken of the mouth over a tenure of treatment years can

indicate deteriorating pathways that are presented to patients so they

can determine how treatment may take place in the challenging life we

all live in. Options can be outlined with pros and cons to be

considered by the patient. Every final pathway chosen by the patient

is the right one for them. When all the details are presented and a

patient chooses their treatment choice, is 100%

in support and driven to provide the absolute best that can be done

for that option.


     We invite you to visit our team at that is

second to none and has provided dental care to over 55,000 patients

over 35 years. Our pace is organized, efficient, and respectful of

your time and dental needs. You will be satisfied and impressed with

your care.

Ten years ago Anklos Implants from Germany offered me an all expense paid trip for training at their Dental School for selected dentists chosen by a specialist Dr. Marco Cueva here in Allen. I was honored to be selected and attended with my wife, Bonnie. architecture was inspired by ideas from this trip. We designed a tour following the week long training and rented a car. The autobahn is unbelievable. I tried to tell Bonnie I wasn't sure how fast 175 kilometers/hour was but it gets you there with time to spare.


   I experienced several amazing things on that trip and immediately began designing and building a pyramid carousel from a memory of one 10 feet tall in Kathy Wolfahrts Christmas shop in Rothenburg. Google images of that place to capture the essence of the experience. I call it a carousel since it rotates like a carousel but they are really called pyramids in Germany. Fredericksburg has one they put up every Christmas in their Marktplatz. In the 14th century, the Germans mined coal and lifted the coal to the surface by lighting fires under fan supported by pyramid shaped lifts that turned with the rising heat from the fires. Now they are table top miniatures powered by candle that feature a manger scene.

   Clarence Carter, a mechanical genius friend of mine, helped by
designing and welding a metal base with a mechanism that started out with a dryer electric motor turning a gear from a lawn mower tractor transmission to a derailleur idler arm from a bicycle with its bicycle chain to turn a wheel barrow wheel up against a wooden disc stage on the first level. Parts assemble up 2 additional levels to finish under the paddles like a big fan mimicking the original full sized pyramids 18 feet tall.

   I took the mechanism and built a wooden structure embellished a
bit. Rough cedar, typical pine 2x4s, some plywood and deck screws
helped. I used a hand held scroll saw to cut curves in the cedar
aprons surrounding each level to add a European look. The design is a
timber frame approach that uses pegs and cauls to put it together
since it has to be disassembled each year. Each level progressed in my
2 car sized wood shop and involved a lot of drawings and erasures.
Things materialized on the fly using a small counter sized model to
follow that we still use to decorate the dental office at at Christmas.

    Hobby Lobby had figurines that fit perfectly to scale. They called
me in on a Saturday to pick them up only to discover it was a half off
day sale. It required a lot of tweaking with the different levels
since the manger scene remains still and the Wise Men rotate around
it. The Sheppard rotates on the second level with his sheep while the
3 Angels on the third level trumpet the amazing event standing still.
Lighting illuminates the entire scene at night where it can be seen on
the lawn of, the SE corner of Exchange Pkwy and
Hwy 75 across from the clear sound barrier Berlin wall. Feel free to
step close to see or take Christmas photos; that's what it's all

The Echo Chamber of Holistic Medicine

Dr. David Bishop, DDS

Dr. David Bishop, DDS

Holistic medicine has made a place for itself with supplemental and medicinal options for our health. Accurate supplemental intake becomes the issue since regulatory entities allow vague concentration descriptions leading one to believe they are receiving something other than what is actually delivered.

Consequently, distrust develops from ineffectiveness. Vitamin C is a case in point; labels do not depict what is actually available from the supplement when ingested.

Which ones work? Be careful since science has quantified the placebo as 30% effective. Anyone might be satisfied with 30% effectiveness if they don’t really want to see it any other way. Are you familiar with “Echo chamber” support? Read internet dialog on any issue and just believe.

What about interesting dental products like charcoal toothpaste?

The cultures from India have used it for centuries? It works by absorbing stains like a poultice? I’m not sure it is abrasive but it might be. Can you convince yourself of some kind of effectiveness? These questions are out in the open since there is no research on it. Do you “want” research evidence? I’ve read money grubbing dentists don’t really want you to find out about it. Really? Fads work off the “echo chamber” momentum.

The intuitive notion that a plastic cutting board is more sanitary than a wooden one but science proves the opposite. Legitimate evaluation comes with trials using many subjects under many environments.


This public acceptance of putting charcoal material in the mouth and convincing themselves of either effectiveness or not is interesting since extremely effective tried and true tested materials in dentistry have been eliminated with public outcry.

This is really an opportunity for a holistic approach in dental hygiene to be tested without FDA intervention and courts to defend some reaction or side effect like stomach cancer, ulcers, tissue slough, or even diarrhea and vomiting. There isn’t any need for dentists to be held responsible or even remotely involved by unusual complications that could show up like needing gallbladder surgery 4 years later.

This new test spirit among people with this charcoal in their mouth are blazing a blind trail once visited by my grandmother when she thought gasoline would reverse the effects of my poison ivy and I at 10 years old was willing to try anything.

Internet dialog is a real good indicator of a successful product like this; right?

As a practicing dentist, I’m ready to accept a successful product as I have reviewed many over my career.

I’d like to review an evaluation using legitimate scientific method before I even discuss it among colleagues. I realize this dialog is like an internet entry. My 35 year practicing career, commitment to my patients and the integrity I exemplify to my long-term staff and colleagues that continue to work by my side should make this information more valuable to you.
