As a Master of the Academy of General Dentistry, Dr. Donnelly has completed over 1,600 hours of continuing dental education, 400 hours of which were hands-on-courses.  These hours are spread across 16 different dental disciplines, ensuring that Dr. Donnelly is well-rounded, and has the ability to offer insightful, comprehensive care to his patients.  In an organization that consists of about 35,000 general dentists, only about 1,900 dentists nationwide have achieved their MAGD.  In 2011 The Academy of General Dentistry announced that Dr. J.

Dr. Donnelly’s practice in the Texas Hill Country offers a full range of services to his patients including preventive dentistry, restorative dentistry, cosmetic dentistry, dentures, implants, root canals, Invisalign, wisdom teeth removals and sedation dentistry.    Dr. Donnelly adds, “I’m fortunate to be part of a wonderful profession where we continually learn, improve, build relationships, and help people regain and maintain their health.  With all the advancements in dental procedures and technology, the field is even more exciting and fulfilling than it has ever been.”

Dr. Donnelly and his wife Kathy were blessed with two sons, a daughter in-law, and granddaughter.

Dr. John K. Drisdale

San Marcos Dentist Dr. J. Robert Donnelly

Dr. Drisdale grew up in the Texas Hill Country, graduating from Lake Travis High School where he played baseball and enjoyed all that the outdoors had to offer. He shadowed his local dentist in high school as a potential career path and appreciated the level of fulfillment he received from helping people maintain or achieve good oral health. From there, he decided to attend dental school at the University of Pittsburgh, where he scored in the 97th percentile in manual dexterity for dentistry and received his DMD. Beyond his traditional education, he’s also received Advanced Laser Certification and training in oral sedation dentistry as well. He is currently active in TMJ research and has published his work in The International Journal of Dentistry. During this part year, he completed over 100 hours of continuing education – which is well above the 12 that are required! He is currently a member of the following organizations:

  • American Dental Association
  • Texas Dental Association
  • Academy of General Dentistry
  • Delta Sigma Delta (Alumni)

After graduating from dental school, Dr. Drisdale couldn’t wait to return to Texas Hill Country. His family consists of his wife Monica, who works at the Texas Academy of General Dentistry in Austin, and their rescued Boston Terrier Waffles. On the weekends outside of work, you can regularly find him cooking, smoking BBQ outside, spending quality time on the lake, or riding his 1970’s Bianchi road bike. He also enjoys volunteering several times a year, giving back to the community by donating his time and dental skills to worthwhile organizations like Dentistry from the Heart and Texas Missions of Mercy.
