Meet Our Doctors


DrGale112016.jpgJohn Gale, D.M.D.

John Gale is the go-to-dentist for implant surgery.  He readily admits there was a time when his enjoyment of dentistry was overcome with the hassles of running a solo practice, but when he started full time at Athens Family Dental in 2012, he found himself in an environment that reignited his passion for the field.

“I worked here part-time for a while even when I had my practice in Cornelia,” Dr. Gale said. “So when I started here full time, I knew all the dentists here and most of the staff, so it felt like a homecoming. At this point in my career, I’m really excited about dentistry again. I have a good peer group to talk to and share ideas with. It’s an open forum around here, and a neat environment.”

A graduate of the Medical College of Georgia in Augusta, Dr. Gale said he worked as a dental lab technician in college and that experience, combined with the influence of his father-in-law who was a dentist, convinced him to apply to dental school.

Prior to joining Athens Family Dental full time in 2012, Dr. Gale owned a solo practice in his hometown of Cornelia, Georgia. The economic slowdown made the practice in the North Georgia mountains more difficult to operate, and Dr. Gale was glad to leave behind some of the headaches of running a business to have the opportunity to focus his efforts entirely on dentistry.  He now has the freedom to serve as editor on the board of the Georgia Academy of General Dentistry. 

Dr. Gale is a member of the American Academy of General Dentistry, the Georgia Academy of General Dentistry, and the American Dental Association.

Dr. Gale and his wife have three adult children.

Dr. CrenshawLeigh Cummings-Crenshaw, D.M.D.

Dr. Leigh Crenshaw sees art in dentistry, and that was what led this Medical College of Georgia graduate into the field of dentistry.

“I wanted to do something in the health field, and I liked the idea of the artistic side of dentistry,” Dr. Crenshaw said. “There is a lot of art to dentistry – color matching, the shapes and forms of teeth. It’s sort of a science and an art combined.”

While it was the artistic side of dentistry that brought her into the field, Dr. Crenshaw said that today what she most enjoys about being a dentist is the relationships she is able to build with her patients.

“Your patients have a lot of trust in you. You see them every six months, and so you build relationships with them,” Dr. Crenshaw said. “Some of the patients I had when they were children now have children of their own that are my patients, and that is very rewarding.”

Dr. Crenshaw describes herself as “an information seeker,” and said she enjoys keeping current on the latest trends in dentistry, but she said the thing that she wants to be known for among her patients is her compassion as a dentist.

“I truly care about my patients,” Dr. Crenshaw said. “We are a very caring group of people here. We look out for the well-being of our patients, and we work well together. I am always impressed with the quality of work that is performed here. We have several areas of expertise at Athens Family Dental and if there is something that one doctor is not comfortable doing, there is always someone who is knowledgeable in that area.”

Dr. Crenshaw completed a general practice residency at the University of Alabama in Birmingham.  Prior to making Athens Family Dental her home in 1999, she briefly worked at a small practice in Macon, Georgia.
Dr. Crenshaw is married and is the mother of one young son.

During her time college, she used her fluency in Spanish to serve as a dental volunteer at Mercy Clinic. Dr. Mackay is Georgia Board Certified and is a member of the Georgia Dental Association and the American Dental Association. 

She is a native of San Pedro Sula, Honduras, but moved to Athens with her parents and siblings in 2006, so she is very excited to serve her hometown again.  On her free time, you can find Dr. Mackay reading, playing soccer, traveling or spending time with her family.

During his time in dental school, Dr. Ali decided to focus on comprehensive dentistry and was passionate about treating the patient and not just the problem.  His hard work and dedication paid off when he was honored by school with the AES Certificate award for a comprehensive case in which he showed advancement of knowledge in the field of occlusion and the temporomandibular joint.  He then received this DMD in general dentistry in May 2019.

Dr. Ali is very excited to work at Athens Family Dental where he is eager to meet new patients and build strong, lasting relationships.  When asked about his goal for transitioning into the office, he said, "My goal is simple.  I strive to provide the highest quality care possible and treat every patient like a member of my family."

Dr. Ali is blessed to have a close mentor in his father, who is also a dentist.  He has learned so much through his father about dentistry, patient relationships, and business.  He plans on utilizing all of these teachings to jumpstart his dental career and is committed to learn new things every day.

Dr. Ali's hobbies include hiking, camping, making music, and playing soccer.  He has always had a fascination with nature and loves to be active.  He has played soccer since he learned how to walk and is committed to continue playing to keep his mind and body stronger.  He loves to make music with his friends and has always allowed his creative side to shine.  You will quickly lean that he loves to laugh and keep the vibe peaceful and fun.
