Dr. Marvin Berlin likes to say he was a dentist before being a dentist was cool. Looking back over 30 years in practice, he can watch as his vision became a reality. “I started my private practice in McKinney in 1993,” he said. “The goal was always to care for the people of McKinney and eventually offer them every dental service they needed under one roof. I was blessed to have my best friend from dental school, Dr. Jeff Lynch, join me in 2005. He shared my vision of a one-stop dental office, and we’ve been lucky to have three outstanding dentists join our team.”

Dr. Berlin says he’d send any member of his family to Dr. Madden, Dr. Morkos, or Dr. Callison. “As the practice grew, we’ve each settled into a dental specialty,” he said. “Now, there isn’t anything we can’t offer our patients right here. If you need a root canal, dentures, dental implants, braces, a smile makeover, or someone to care for your young children, you can stay here with a dental team you know and trust.”

Dr. Berlin himself concentrates on cosmetic dentistry. “I’ve always been passionate about the cosmetic aspect of dentistry,” he said. “It’s about more than making you look gorgeous. It’s about building confidence. Patients hold themselves better in their personal lives and in their professional life. They go from trying to hide their smile to proudly showing it off. It’s a great ride to work each morning knowing I’ll be doing what I love and changing lives.” These days, Dr. Berlin finds himself providing state-of-the-art cosmetic services to patients from North Carolina, Arkansas, Indiana, Illinois, Louisiana, and beyond and working on many dentists and their families. At, patients can upload a selfie and description of the changes they want and have a virtual consultation with Dr. Berlin before coming to the practice.

Meanwhile, Dr. Lynch concentrates on implants and oral surgery within a separate dedicated wing of McKinney Dentist with spacious hospital suites and a board-certified anesthesiologist on staff. He offers Teeth Tomorrow, a full-arch bridge of strong, healthy teeth anchored by permanent dental implants, for a permanent solution to major dental problems. Drs. Madden and Morkos are concentrating on general restorative and comprehensive dentistry. Both perform wisdom tooth extractions and other oral surgeries, as needed. Dr. Callison brings to the practice extensive orthodontic knowledge and the latest braces technology including interventional orthodontics for kids, general orthodontics, and Invisalign Clear Tooth Aligners for kids and adults.

“I’m blessed with an amazing team and four of the best partners on the planet,” Dr. Berlin said. “My partners are some of my best friends who share my servant’s heart and patient-first mentality.”
