Joni Thomas


Joni has been managing the NDDA Skin and Laser Spa since 2010 and believes her focus on excellent patient care is instrumental to her success. When she is not investing time in learning about the latest and greatest technology, she enjoys spending time with her family, cheering a little too loudly at Dallas Mavericks games, and exploring new locations across the USA.

Care Philosophy

Joni believes that investing in your skin is a benefit that lasts a lifetime and is an ambassador for the benefits of using high quality products herself. “Treatment options we provide have far better outcomes if the foundation of your skin is solid, and habits like applying a broad spectrum sunscreen every day will protect your investment”.She has a goal of keeping her entire Spa team in Continuing Education and hands on training to be up to date on the newest lasers and treatments available


A native Texan, Joni has spent her entire career working in dermatology and has worked with well renowned doctors, learning their strategies for making patient’s look and feel their best. She has extensive knowledge in high end skincare lines such as IS Clinical, Revision, Elta MD and Biopelle; and was instrumental in securing NDDAs Flagship status for Skinceuticals.

Becky Shepard


A native of Tallahassee, Florida, Becky moved to Dallas the first time in 2004 and then permanently in 2012. She enjoys spending time with her beloved husband Brad as well as travelling, cycling classes and Pilates.

Care Philosophy

Becky believes that no treatment or procedure works in a vaccum, and devises bespoke plans for her patients that allow for the best possible result. “Just as you can’t do one spin class and take on the Tour De France, very rarely will one single treatment give you exceptional results so I tailor combinations of lasers and peels or skin tightening to create incredible results, and combine with advanced home care to ensure the results are maintained.”


A native of Tallahassee, Florida, Becky moved to Dallas the first time in 2004 and then permanently in 2012. She has trained with ‘best in class’ providers in both Texas and Florida and uses her vast knowledge to identify better treatment protocols for the Skin and Laser Spa. She single handedly established an Aesthetics division for one of the largest Ob/Gyn practices in her home town, specializing in providing services in skin care and medical lasers.

Care Philosophy

Allison’s expertise includes a wide range of treatments, but her favorite treatment for patients is Intense Pulsed Light (IPL). “My patients are incredibly happy with their choice to undertake a series of these treatments, as you can notice incredible results in a short space of time, and who doesn’t want to show off clear, glowing skin?”.


Allison received her qualification from I.T.S. Acadamy of Beauty in Plano, and has been to advanced training classes for Coolsculpting, Ultherapy, medical grade peels and Laser therapy.
