Leslie began her career in the skin care industry nearly 12 years ago, during which time she had the opportunity to work in some of Houston’s most prestigious medical spas, as well as train alongside renowned medical doctors, registered nurses and aestheticians both regionally and nationally. As a certified cosmetic laser technician and aesthetician with a background in plastic surgery and aesthetic dermatology, Leslie has experienced first-hand the continuous improvements in skin care and aesthetic medicine. 

Leslie attends numerous advanced training courses focusing on cutting edge non-surgical techniques including botox and dermal filler injections, chemical peels, laser hair removal, IPL photo-rejuvenation, fractional skin resurfacing as well as body contouring and cellulite reduction. She believes on-going education is the key to a successful business and prides herself in her ability to provide patients with the latest in-demand treatments using gold standard products and champion technology. 

As a spa owner, Leslie strives to set Royal Aesthetics apart from the typical spa business model by combining the luxurious spa ambiance with the successful results of aesthetic medicine. She works one-on-one with each patient to personally tailor a treatment plan to address each of their concerns, whether that be through a series of in-office laser procedures, or a customized skincare regimen with products that can used at home. She also realizes that achieving these goals can be costly and works with each client to develop a treatment plan that fits within their budget as best she can to work toward their desired result. 

Leslie is excited to announce the Grand Opening of her new location at Uptown Salons in The Woodlands, where she is eager to introduce a beautiful atmosphere that also allows for greater privacy, yet improved accessibility - ultimately improving her ability to continue growing as a businesswoman, and sharing her royal skin care regimen and expertise with more clients throughout the North Houston area.

Isabella Pethe/BioWellness offers a unique - and effective - bioidentical experience. Unlike other sources that simply "dose and dismiss", Isabella approaches her work uniquely, focusing on each patient's specific needs, customizing a plan with natural solutions - and overall balance. She builds honest, caring,

long-term relationships with her patients. After turning forty, I noticed a drastic change in my weight, energy levels, emotional state, and, started experiencing hair loss.  I have been under Isabella's care for four years - and will continue as long and she will have me!  Thanks to her unyielding dedication to her patients' well-being, I am now a whole, healthy, happy, and energetic person once again.  I have the energy and balance needed to run my business, which would not have been the case if the standard (Western medicine/chemical) approach to women's health had been my only option.  Treat yourself and change your life....see Isabella.  She certainly changed mine.
