Dr. Holly McKinney

Dr. Holly Hertel McKinney grew up in St. Louis, Missouri. She received her BA from the University of Missouri, in Kansas City.

After college, she worked as a technician in a hospital cytology laboratory. During that period of her life, she represented her church on an outreach program to Jamaica. Since there were no hospital laboratories onsite in Jamaica, she assisted a dentist and it was then that she decided to pursue a career in the dental field.

In 1999, she graduated from the New York University College of Dentistry and has worked as a private practitioner in Connecticut, Missouri, and Texas.

Outside of work, she enjoys gardening and spending time with her family, including her Great Dane, Griffin.

Dr. Donna Rollins

Dr. Donna Rollins was born and raised in San Antonio, Texas. She graduated from St. Mary’s University in San Antonio in 1991 with a Bachelors in Biology and a Minor in Chemistry before moving to Dallas to attend Baylor College of Dentistry. She graduated from Baylor College of Dentistry with her DDS in 1995.


Her commitment to you is that she will listen to your concerns and address them individually, building the foundation for a solid, lasting relationship.

Dr. Rollins does not practice cookie-cutter dentistry; she evaluates each patient’s needs and designs a treatment plan as unique as you are. Optimum oral health for every patient sums up our goal. We know that the most expensive thing in dentistry is neglect.

Dr. Rollins recently closed her practice in Garland to join Mockingbird Dental Group. She is excited to be part of such a professional and caring team dedicated to patient care.

When not providing quality dental care to her patients, Dr. Rollins enjoys spending time with her husband and two wonderful sons.
