Meet the Team

Dr. Preston McAlexander grew up in Holly Springs, MS and attended the University of Mississippi where he received his undergraduate degree in 1999. He continued his studies at the University of Mississippi Medical Center and was awarded the Doctor of Dental Medicine degree in 2004. While at the School of Dentistry, he served as student body present and representative to the American Dental Association.  

Dr. McAlexander worked for five years in a community health center dental clinic as part of the National Health Service Corps. He is a member of the Mississippi Dental Association and the American Dental Association.  

At the health center dental clinic, Dr. McAlexander was able to see first-hand the impact that quality dental services can have on a family. He is proud to continue his work to bring great dental care to all children, regardless of their family income.  
 
Dr. McAlexander enjoys life outside the office with his wife and two kids. He is an active member of his local United Methodist Church.  

Dr. Kristen Douglas is a native of Mississippi’s sister state, Alabama, but has spent the last 16 years calling Mississippi her home. She received her BS from Mississippi College, and went on to graduate from the University of Mississippi Medical Center, School of Dentistry.  

Before and during dental school, Dr. Kristen worked for a pediatric dentist and quickly realized how fun it was to work with children and their parents. In 2016, she completed a two-year pediatric dental residency at the University of Tennessee Health Science Center. While in residency, she had the unique opportunity to rotate through St. Jude and LeBonheur Children’s Hospitals as a part of her training.  
 
Dr. Kristen is a Diplomate of the American Board of Pediatric Dentistry and is currently a member of the American Academy of Pediatric Dentistry, the Mississippi Dental Association, and the American Dental Association.  
 
Outside of the clinic, Dr. Kristen makes her home with her husband and daughter. She would say that being a mother has greatly impacted how she practices. With so much information to process and decisions to make, she understands the challenges that parents face when it comes to making healthcare choices for their children. She considers it a privilege to be trusted with the care of your child.  

Dr. Sarah Crain grew up in nearby Holly Springs, MS. No surprise, she attended Ole Miss where she received a B.S. in Biological Sciences in 2004. From there, she was accepted into the University of Mississippi School of Dentistry and was awarded the Doctor of Dental Medicine degree in 2008.  
 
The following year, she was a resident within the Advanced Education in General Dentistry Program at UMC. Having always loved kids, she decided to focus her career on dentistry for children and began her career as a practicing dentist in 2009. 
 
She is a proud member of the Mississippi Dental Association, American Dental Association and Mississippi Association of Women Dentists. 

Dr. Crain recently moved to Olive Branch and attends St. Timothy’s Episcopal Church.  

Dr. Jessica Daves grew up in Meridian, MS and graduated from Mississippi State University in 2009 with a B.S. in Biological Sciences. She received her Doctor of Dental Surgery at the University of Tennessee in 2013. 

While in dental school, Dr. Daves served as the ASDA secretary. She is a member of the Mississippi Dental Association and the Academy of General Dentistry.

Dr. Daves was drawn to practicing children's dentistry because she feels it is a unique opportunity to truly make a difference in their lives. If they start having a great experience at the dentist from day one, they are more likely to maintain their excellent oral health. 

Dr. Daves and her family make their home in nearby Memphis, TN. She is an active member of Christ United Methodist Church. 

Dr. Jason Leach was born and raised in Jackson, MS. He is proud of his Alma Mater, Ole’ Miss, having earned both his undergraduate degree and his Doctor of Dental Medicine from the University of Mississippi.  

Dr. Leach believes in providing the children he serves with the very same treatment he would want his own kids to receive. By all the smiling faces in his dental chair, we think he is succeeding! 
 
A leading dentist in our mobile dentistry outreach program, Dr. Leach is passionate about helping families access critical preventative services for their children. This program partners with our local schools and Head Start to help improve health outcomes for the children they support.  

In the mobile program and at the office, Dr. Leach encourages healthy habits that will prevent tooth decay in Mississippi children.  
 
Dr. Leach spends his spare time with his wife and two kids. What could be better than that?

Dr. Sydney Collette grew up in Kingsport, Tennessee. She went on to study Chemistry at the University of Tennessee. While in her undergraduate studies, she realized she wanted a career where she could help people, work with her hands, and constantly experience new things. 

Lucky for us, dentistry checked all three boxes.

Dr. Collette went on to the University of Tennessee Health Science Center in Memphis where she earned her Doctor of Dental Surgery. She was ready to begin practicing as a dentist, but where? How? 

Dr. Collette's has a passion for adventure, and it led her to kids dentistry. As any parent can attest, you never quite know what a kid might do or say. Every day is an adventure when kids are in the dental chair!
