Drs. Marvin Berlin, Jeff Lynch, Trevor Madden, Kero Morkos, Anthony Callison, and Practice Administrator Tosha Searls


Whatever you need when it comes to your smile and oral health, you can find under one roof at That’s the promise and the goal of this dynamic leadership team, including five experienced dentists, longtime practice administrator, Tosha Searls, and their team. The internet is overflowing with enthusiastic reviews—over 1,300 of them—from families who’ve trusted their oral health to this team and have a lot to say about it. They use words like “kind, talented, patient, friendly, incomparable, accommodating, exceptional, compassionate”—even “da bomb”.

As the practice has grown, each of the dentists has settled into his own niche. And though the five doctors often consult with each other, having each chosen their own unique focus area has allowed them to attain a breadth and depth of training and experience. We thought you’d like to meet them.

Marvin Berlin, DDS

Now concentrating on cosmetic dentistry, Founding Dentist Dr. Berlin can take your smile from drab to fab with a cosmetic smile makeover, including porcelain veneers, cosmetic bonding, professional teeth whitening, and more.

Dr. Berlin can upgrade your smile or create a whole new one. “Patients can also have a virtual smile consult,” he said. “Potential patients wanting a new smile can visit our website, upload a selfie, and send it to me. I’ll send them back a personalized video showing how we can upgrade their smile. If you’ve ever wondered what porcelain veneers might look like, I can walk you through the entire process, with your own personalized video consultation.”

Once you decide which procedures you’d like, Dr. Berlin can even let you test drive your new smile for a few days, creating a temporary smile. Then, you can take it (remove it) home to show family and friends.

Jeff Lynch, DDS

Dr. Lynch is concentrating on implants and surgery and has even dedicated a separate wing of McKinney Dentist 100% to oral surgery with spacious hospital suites and a board-certified anesthesiologist on staff. “Dr. Lynch is one of the country’s most gifted clinicians,” Dr. Berlin said. “He’s sought after as a mentor and teacher for dentists around the country and he has a unique gift for solving even the most difficult dental situations.”

If you’re missing teeth or wear dentures, Dr. Lynch can give you the freedom of a full set of strong, healthy teeth with permanent dental implants. Unlike other prosthetics, dental implants are individually secured into the jawbone. They promote jawbone retention and require no alteration of or support from surrounding teeth. You can have beautiful, fully functioning teeth, for a natural-looking smile again.

Esteem Dental Implants provide a full-arch attached bridge for a permanent solution to major dental problems. Dr. Lynch anchors the bridge to dental implants that replace your teeth, and you never take it out. Your full-arch bridge implant looks like naturally healthy teeth and gums but don’t attract plaque and won’t chip or break. Stop living with missing, decaying, and broken teeth or unreliable dentures. Your implant-supported bridge is like normal teeth. You can eat and smile with confidence. And a five-year study published in the Journal of Prosthetic Dentistry showed them to have an over 99% success rate.

Anthony Callison, DDS

Dr. Callison is helping patients enjoy beautiful, healthy, fully functioning smiles — at any age — with Invisalign. Properly aligned teeth not only look great and give you confidence, but they’re easy to keep clean and less apt to break or wear down. Invisalign uses sets of plastic aligners Dr. Callison custom fits to your bite. Because he creates them using a state-of-the-art iTero intra-oral scanner, impressions are obtained instantaneously with no messy molds. The scanner also ensures your orthodontic treatment is as customized as possible.

Your clear aligners are worn for 1-2 weeks at a time to shift your teeth into proper alignment, often in less time than traditional braces. As you advance through sets of Invisalign aligners, your teeth are gradually adjusted without the soreness associated with traditional metal braces. By the end of your treatment, you’ll have beautiful straight teeth that boost your confidence, function properly, and are easier to keep clean.

Kero Morkos, DDS

“Dr. Morkos is the millennial of the bunch,” Dr. Berlin said. “He keeps us current with the latest digital dentistry, including advanced digital scanners.” McKinney Dentist has invested in five such scanners which enable the doctors to instantly show patients what they’d look like after Invisalign or after a cosmetic surgery procedure.

“They also allow us to capture digital images for crowns or bridges without messy, goopy impression material. Instead of waiting for weeks for a case to go to the lab, we click a button and they have it immediately,” said Dr. Morkos, who also performs wisdom teeth extraction and places implants.

Trevor Madden, DDS

Drs. Madden and Morkos concentrate on comprehensive restorative dentistry. They both remove wisdom teeth and perform other oral surgeries, as needed. “There’s really nothing general about general dentistry,” Dr. Berlin said. “Increasingly, research has shown that the same bacteria causing inflammation in the gums enters the body as a person swallows, producing inflammation in the major arteries and veins in the rest of the body — including the heart. Links have been established between gum disease and diabetes, Alzheimer’s, heart disease, and other life-threatening conditions. It’s more important than ever to stay on top of regular checkups with a qualified dentist like Dr. Morkos or Dr. Madden.”

With all these dental offerings under one roof, not only do the doctors have a built-in second opinion, but your family can receive all your dental care at a practice where you’re already comfortable. It’s no wonder generations of McKinney families are trusting all their oral health needs to where they’re always accepting new patients.
