About Us

Dr. Garrett E. Phipps

Dr. Garrett E. Phipps grew up in Amarillo, Texas where he graduated from Tascosa High School in 1998. He then attended Lubbock Christian University where he earned a degree in biology graduating Summa Cum Laude. He received his doctor of dental surgery degree from the University of Texas Dental Branch in Houston, which is now referred to as the University of Texas School of Dentistry. Before practicing in Guymon, Dr. Phipps worked for Dr. David Woodburn in Amarillo for over two years where he gained valuable experience. Then, in January 2009, Dr. Phipps took over the Gibson Dental Clinic in Guymon. He took over the practice that had been serving this community well and provided quality care for many years. He built on to the foundation that the Gibson’s started, implementing more technology and updates to enhance patients’ dental experience. In 2012, Dr. Phipps married his beautiful wife, Casey, and they have three children ― Kylee, Parker, and Allie.

Dr. Phipps has a passion for delivering high-quality dentistry in a professional environment, while always making his patients feel comfortable and at-ease. His goal is for every patient to achieve optimal oral health and to feel like they are a valued member of the Phipps Dental Practice family.


Dr. Emily Donnell

Dr. Emily Donnell was born in Amarillo and raised on a farm just outside of town. Growing up Dr. Donnell was good at science, math and enjoyed working with her hands. She graduated from West Texas A&M in 2015 and attended the University of Texas School of Dentistry in Houston, earning her DDS in 2019. After practicing general dentistry in Houston she decided to move back closer to her family. She chose dentistry because it allows her to combine love of science and working with her hands to make a difference in people’s lives.

Dr. Donnell is a member of the American Dental Association, Texas Dental Association and the Seattle Study Club. She has also completed continuing education courses on Laser Dentistry and Invisalign.

Outside of work she enjoys spending time outdoors, traveling, golfing, trying new food, photography, and playing with her dog Simba.

DID YOU KNOW: When she was 7 years old Dr. Donnell had her front teeth knocked out with a baseball bat. After her dentist fixed them she thought he was so cool that she wanted to be just like him.
