Dr. Valerie Warren
Setting a new whole-health trend in dentistry.
We would like to introduce you to Dr. Valerie Warren. Dr. Warren has been practicing dentistry for 19 years and is very excited to join our team at the Center for Holistic and Biological Dentistry. Dr. Warren loves to connect with patients and show them how the right kind of dentistry can enhance their life. Dr. Valerie Warren has always been an advocate for continued education as it allows her to pass her knowledge onto her patients and guide her patients to a sustainable health routine. Dr. Valerie graduated from University of Kentucky College of Dentistry in 2001.
‘‘I strive to provide you with the best care available, in the best facility available, from an honest, kind, and caring provider. One who has the highest level of education and who’ll treat you like her own family.”
Born and raised in Owensboro, KY, I knew I wanted a career that provided me the opportunity to care for and connect with people. I explored all aspects of healthcare and decided dentistry allowed me to combine my love for people, holistic/ functional health, science, beauty, and art.
I am a very sensitive person. I like it when people smile at me. From the time I was a little girl, I judged whether I had gained a teacher’s approval by whether she smiled at me or not. This led me to my belief that a smile, both given and received, can change the way we feel and live.
My passion for practicing a functional, holistic model of healthcare is grounded in my family’s own personal health journey. I learned through this, the importance of nutrition, sleep, and stress in our overall health and wellness. My commitment lies in helping each of my patients achieve their healthiest smile and self.
Away from dentistry, I love to exercise, anything nutrition and health-related, and I love being a mom to my amazing boys.

Dr. Lydia Lancaster, DDS, MS
Dr. Lydia Lancaster is passionate about helping people with her passion for oral healthcare and orthodontics by creating beautiful, functional smiles. Creating a positive relationship with her patients is the most satisfying part of the job for her. She was inspired to enter dentistry by her hometown general dentist, a longtime mentor. While doing her dental school studies, she decided to specialize in orthodontics.
Dr. Lancaster earned a Bachelor of Science in Biology at Rhodes College in 2011 and her DDS, MS in Dentistry, and Certificate in Orthodontics at The Ohio State University. She is passionate about timing treatment for each patient’s individual growth and development. She is also pursuing additional training in airway and obstructive sleep apnea management, as well as advancing her TMD therapies.
In her free time, Dr. Lancaster likes to travel and spend time with her husband, Adam, and her standard poodle, Hugo.
Whether it be skiing, cycling, or hiking together, she loves outdoor activities with her family. She is also a lifelong musician. She was a choir enthusiast throughout her adolescence and has been a pianist since the age of six. She is also a big OSU Buckeye fan, especially during football season.
Having grown up in a farming family in rural Southeast Missouri, she is very grateful to live in Nashville, being much closer to her roots. She and her family love being part of Music City, serving the Middle Tennessee community and beyond.
After working in the Nashville metropolitan area for almost a year now, Dr. Lancaster is enthusiastic about the future of her role in this practice. She appreciates the special culture of the Centre of Holistic and Biological Dentistry, which aligns greatly with her own orthodontic philosophy of early expansion and non-extraction.
She looks forward to getting to know each of you and helping address your orthodontic needs. If you are interested in correcting your alignment or functional bite issues, for yourself or your child, schedule an orthodontic consult for more information!

Dr. Thomas Garitty, DDS
Dr. Thomas Garitty has been practicing dentistry since 2016 when he graduated from The Louisiana State University School of Dentistry. He then went on to complete a General Practice Residency at Oklahoma University Children’s Hospital in Oklahoma City and a Pediatric Dentistry Residency at Children’s Hospital in New Orleans and the LSU School of Dentistry.
Dr. Garitty chose dentistry because of his passion for science and the fact that he is able to work with his hands.

Dr. Chapman , DDS
Dr. Chapman is originally from San Antonio, Texas and completed his undergraduate studies at Texas A&M University. He obtained his dental education in his hometown of San Antonio at the University of Texas Health Science Center, graduating in 1998. He moved to middle Tennessee to take his first associate dental position in Madison and join the songwriting scene in Nashville.
In 2004, Dr. Chapman chose a different path in dentistry, and he began working as a missionary for the organization Mercy Ships, and continued working with them for the next eight years. It is here that Dr. Chapman began to gain extensive surgical experience under Mercy Ships’ long term oral surgeon Gary Parker and developed a passion for oral surgery. After his four years aboard Mercy Ships, Dr. Chapman and his family moved full time to Liberia and co-founded Trinity Dental Clinic. He is very happy that, to this day, the clinic continues to provide affordable dentistry to thousands of patients a year in Liberia and has trained several Liberians as assistants, lab technicians, and practitioners.
In 2012, Dr. Chapman returned to Franklin, Tennessee to allow his four children to finish their schooling. He then completed his implant training with Zimmer Biomet in Carlsbad, California. Dr. Chapman also has extensive experience in smile makeovers and cosmetic dentistry. Dr. Chapman has four children, a foster son who still lives in Liberia, two step-daughters, a granddaughter and two dogs. He is an avid surfer (which he picked up in West Africa), marathoner (inspired by his wife, Ninette) and triathlete. He keeps performing and writing music, and is a huge movie buff.Like a lot of runners, he and Ninette are always training for the next race and Dr. Chapman
considers it his “part time job”!
“Really my biggest passion in dentistry is connecting with my patients and taking time to hear and work through anxieties and concerns around dental treatment, making them as comfortable as possible. The wide variety of treatment options and restorations available in dentistry keeps my passion strong for helping patients restore their smile, chewing ability, and overall health. It gives me great satisfaction to know that improving oral health is significantly linked to improving systemic health. I would want every patient to know how many areas of their health are affected by their oral health – heart, systemic health, and of course improved nutrition from better diet and chewing ability! I have moved significantly from treating individual teeth into making sure I approach each patient comprehensively to obtain the best long term, long-lasting solution and minimize future treatment needs.”
