About Us

Facials, laser Treatments, anti-aging, skin care, and more in Duluth, Georgia!

Eighteen years ago, Doctors Jacqueline Walters and Katia Castillo came together to create an oasis where clients would get aesthetic treatments and walk out saying, “Wow,” completely thrilled with their results. Countless “wowed” clients and 18 years later, we just keep getting better and stronger each and every day – and our clients experience the same effect, too!

Dr. Katia Castillo and Dr. Jacqueline Walters are both board certified OBGYN physicians. They have partnered for nearly two decades to provide quality obstetrical and gynecological care. Devoted to treating women in all stages of life, their extreme passion for delivering complete women’s wellness has segued into aesthetics for women and men, too, igniting the creation of WOW. By combining aesthetics with medicine, they harmonize internal and external wellness for true happiness and self-confidence.

In Duluth, just 15 minutes north of Atlanta on a good-traffic day, Wow Medi Spa helps women and men achieve natural yet astounding beautification. We offer a broad range of aesthetic services and operate under the full-time supervision of a physician. Doctors Castillo and Walters employ only the best in the business – pros whose standards and expertise are matched only by their passion for healing women and men, both inside and out. We take the time to get to know what you care about to give you the results you desire.

At Wow Medi Spa, you will receive first class treatments from fully licensed and certified aestheticians in a nurturing environment. When your treatments are completed, you will be self-assured, looking radiant, and feeling healthier. We want and expect you to say, “Wow.”
