Our Staff


At the heart of an exceptional plastic surgery practice is its staff. At Commonwealth Plastic Surgery in Lexington and London, KY, our team of qualified, knowledgeable, and caring professionals was hand-selected by Dr. Dowden to provide the highest level of care for the people of our community. These dedicated individuals chose to stay on with Dr. Nimtz and continue providing the exceptional standard of care that was established. We are proud of the family atmosphere our people project and the fact that most are familiar faces our patients have known for years.

Renee Nimtz

Renee Nimtz – Director of Operations

Renee is relatively new to the Bluegrass State as a transplant from Southern California. Her life has gone through a complete overhaul from being an English professor to running a medical practice in Kentucky. Renee and Dr. Nimtz own a small farm, so she helps raise their cows, chickens, and horse, not to mention their 6 kids. In the wee hours of the morning, you will find her running or cycling. When time permits, Renee enjoys exploring new cities.

Mary Osbourne

Mary Osborne – Nurse

After working 6 years as an LPN at Good Samaritan Hospital’s medical surgical floor, Mary interviewed with Dr. William Dowden to become his office nurse.  She worked with Dr. Dowden for 38 years.  When Dr. Nimtz took over the practice, the high quality of care in plastic and reconstructive surgery remained. Computer imaging has been an important part of our practice for many years and Mary considers it the exciting part of her job description.  In her free time, she enjoy cooking, gardening, and constantly redecorating her home.

Leticia “Tisha” Ducas – Skincare Nurse

Tisha was employed at St. Joseph Hospital when she first had the pleasure of meeting Dr. Dowden. He asked her to join his practice in 2006 to train in the use of cosmetic lasers. In 2011, Dr. Dowden invited Tisha to develop a skincare service within his practice. She received  training through Skinceuticals. Her 20+ years of combined service in laser, skincare, perioperative plastic and surgical nursing, and perinatal research includes 11 years with this practice. She earned an RN-BSN from the University of Kentucky.

Tisha truly values the opportunity to become acquainted with the people she treats. “There is no greater satisfaction than knowing I have played a part in someone leaving the office feeling better about themselves,” she explained.

Blessed to be surrounded by a family of 4 men, Tisha enjoys spending time with them on Lake Cumberland along with various outdoor adventures, cooking, and gardening.
