Meet the Doctor

Dr. Kristy Castles

Dr. Kristy Castles, formerly Dr. Greenfield, is originally from Richmond, Virginia, where she grew up with a less-than-perfect smile. An elbow to the mouth while she had braces in middle school caused one of her front teeth to come loose and turn gray. Fortunately, her dentist was able to save her tooth, and her self-confidence. This personal experience made her realize the impact dentists can have on their patients’ lives, and she decided she wanted to provide this valuable service to others.


Dr. Castles graduated from the University of Virginia with a degree in Biology and received her Doctor of Dental Surgery degree at the Medical College of Virginia. She continued her education at the Medical University of South Carolina with a residency in Advanced Education in General Dentistry, which is when she fell in love with Charleston.

Why She Started Her Own Dental Practice

After working in other dental offices, Dr. Castles decided to start her own practice so she could provide the quality care she believes every patient deserves. She prefers to focus on establishing personal relationships with her patients rather than the bottom line, and prides herself in her attention to detail and commitment to perfection.

Part of providing top-notch treatment is staying informed about the latest dental techniques and technology. Not only does she attend continuing education sessions and dental conferences, Dr. Castles' husband can also attest to the fact that she is constantly researching and continuing to expand her knowledge of dentistry.

Community Service and Membership

Dr. Castles' passion for helping others spans much further than the walls of her dental practice, and she has participated in over 10 dental mission trips thus far, both locally and abroad. She also regularly volunteers at Our Lady of Mercy Community Outreach, a free dental clinic located on John’s Island for those in need. She is a member of the American Dental Association, South Carolina Dental Association and Academy of General Dentists.

Dr. Castles currently lives in West Ashley with her husband, Guy, and their golden retriever, Dawson. In her free time, she enjoys traveling, horseback riding, fishing and exercising.
