Dr. McGhee grew up in Richmond, a community just outside of Houston. Her passion for dentistry started pretty young.  As early as age 12, she knew she wanted to be a dentist (she even went to her 5th grade career day as one!). She attended Texas State University for undergrad, where she graduated with summa cum laude honors and first in her class. She then went on to earn her Doctor of Dental Surgery (DDS) degree from the University of Texas Health Science Center at Houston School of Dentistry. Upon graduation in 2019, Dr. McGhee moved to Dallas, where she began her dental career and grew in her passion for oral-systemic health.  

Dr. McGhee strongly believes that not only can your smile boost your confidence but it can also play a huge role in your overall health. This passion and love for treating the whole patient and not just their teeth, has brought Dr. McGhee to Dallas Functional Dentistry with Dr. Tevis, where oral health meets systemic health. Dr. McGhee is excited and feels so privileged to get to treat the amazing patient family at Dallas Functional Dentistry. Her warm, bubbly personality will make you feel right at home. She takes great pride in getting to know each patient personally and creating the best individualized treatment plan.
