Dr. Mark H. Kogut
DDS, MSD

I must be one of the luckiest people in the world! I arise every morning excited about the day and coming to work with a dedicated team of doctors and individuals that have become a “family,” and who have the privilege of making a difference in the lives of children. The feeling is, as the commercial says, priceless.

I grew up in Austin and lived there until I graduated from the University of Texas with a degree in psychology. While at U.T. I married Mimi, a girl from Dallas, and we moved here, where I earned my dental degree and then studied to become a pediatric dentist. Upon completion of my master’s degree and certification in pediatric dentistry, I began private practice and have been here ever since.

Dr. Alejandra Villaseñor
DDS, MS

Alejandra Villaseñor is my name, however, as a pediatric dentist my patients know me as “Dr. Alex”. I have been in practice since 1990 after completing the Baylor College of Dentistry Pediatric program.  I also completed a fellowship followed by an academic position with the Children’s Hospital in Denver, Colorado with a special focus on childhood cancer. Locally, I received specialty training at Children’s Medical Center and served as Assistant Director of Dental Services at Texas Scottish Rite Hospital for Children.

I enjoy yearly continuing education courses in order to offer the most current preventive and treatment options available in pediatric dentistry. Soft tissue laser procedures, cosmetic dentistry and behavior management are areas in which I have extensive training.

Dr. Glenn Cohen
DMD, MS

As a kid growing up in Miami, Florida I could never have imagined life’s twists and turns that would bring me to work with the incredible team of doctors and staff at myKIDSdds. Collectively they provide the most amazing compilation of knowledge and caring I’ve ever seen in a dental office and I feel so privileged to join them.

I never thought I’d be a dentist. As a child, my pediatric dental experience was nothing like that provided by Dr. Kogut and Dr. Villaseñor. My fear of dentistry didn’t change until I was a senior in High School and I visited the orthodontist for the first time. I had terrible self-esteem, lacked confidence, and didn’t smile. My entire personality changed when I became proud to smile.

Dr. Gayle Glenn
DDS, MS

At an early age I knew that I wanted to be an orthodontist. I experienced first-hand how orthodontic treatment can transform one’s life by improving self-esteem and self-confidence. As a Board Certified Orthodontist, I feel blessed to be able to return the favor to others.

Born and raised in Texas, I began practicing orthodontics in Dallas in 1984. After graduating as valedictorian of the University of Texas – Dental in San Antonio, I went on to specialize in orthodontics at Baylor College of Dentistry. My practice focus is on the treatment of children and adolescents, as that has been my area of special interest throughout my career.
