Leslie Wetmore, CDT

Leslie Wetmore, CDT | Office Manager

Leslie has been in dentistry since 1976. She is a talented Certified Dental Lab Technician. She has taught at Nova Southeastern Dental School, and ran their dental lab, as well has owned her own private dental lab. Leslie worked with Dr. Tiwana at UNC Chapel Hill in the Dental Faculty Practice as her invaluable, trusted dental assistant for eight years before retiring. Dr. Tiwana coaxed her out of retirement to come work with her at Chatham Dental Arts. Leslie runs mission control (our front desk) at the practice, and helps our patient’s file insurance and coordinates their treatment. She genuinely cares about our patients, and often has baked goodies for them to eat! In Leslie’s spare time she enjoys spending time with Liam, her adorable Biewer Terrier, her grandchildren, and gardening.
