Meet The Doctors




Dr. Lisa McDonald, DMD

Dr. Lisa McDonald graduated from Southern Illinois University School of Dental Medicine in 2001 and since that time through advanced studies, teaching, and full time private practice, she has developed a remarkably high level of clinical proficiency. She brings with her a wide variety of services including clear aligner therapy, surgical procedures, and implant services, along with the same excellent preventative and restorative care that you deserve. Dr. McDonald has recently become certified in “Vivos” sleep apnea treatment and is passionate about helping all of her patients breathe well and find comfortable treatment for sleep apnea. Dr. McDonald approaches patient care in a caring and compassionate manner. She always puts the patient first and treats everyone like members of her family!


Dr. McDonald is a member of the American Dental Association, the Missouri Dental Association, as well as the Greater St. Louis Dental Society. Dr. McDonald lives in Des Peres and enjoys spending time with her daughter Ava.  Cycling has become a fun hobby and passion and Dr. McDonald loves exploring all of the great St. Louis trails.


Dr. Merna Megalla

Dr. Merna Megalla grew up in Ottawa, Canada before pursuing her studies at the University of Toronto, earning her Doctor of Dental Surgery degree with honors. She also completed a Bachelor of Food Science and Nutrition which sparked her connection between nutrition, oral health and systemic health. Dedicated to lifelong learning, Merna has sought out continuing education with some of the most prominent leaders in the field to master all aspects of dentistry. While Merna enjoys all disciplines of dentistry, she has a special interest in restoring smiles. 

Merna strives to provide an exceptional dental experience and the highest quality of care for all her patients. Her core values of integrity, empathy, and excellence guide her practice, where she treats every patient with the same respect and kindness she would expect for herself. She is committed to creating a positive and comfortable environment for all of her patients, ensuring they feel heard and well-cared for.
