About Us



As the owner and operator of Serendipity Skin Care, Gina Harper has been a licensed professional in the esthetics industry since 2009. Gina also holds a license in Makeup Artistry, is Reiki Attuned and Certified, and in 2014, became a Certified RYT-200 Yoga Teacher.

"After working for a big named Skin Care Company for almost 5 years I decided it was time to branch out on my own. The space I have is small and comfortable.

It's not an upscale, pretentious, over the top type of spa. I truly believe that all people deserve to have their skin taken care of at a price they can afford and that is my goal here at the spa."

Services include a variety of facials and waxing as well as overall skin care education.
