Flash Lab was opened in June of 2016 by New York state licensed esthetician and laser specialist Kelly Rheel.  It has been owner-operated ever since. After spending years developing her skills in various areas of the esthetics industry, it was Kelly’s goal to ultimately offer something she had yet to come across in her career: 


From our state of the art equipment to our focused and friendly service, Flash Lab has been designed to provide you the most personalized, well rounded, effective and comfortable customer experience available. From start to finish, every detail of your treatment is carefully considered by the spa’s staff to ensure top quality care in the most welcoming environment.





Kelly began her career as a medical esthetician working under the tutelage of one of the country’s most prominent dermatologists. Since 2008 she has specialized in various areas of skincare including the treatment of acne, pigmentation and age related issues to a variety of laser treatments with a focus on hair removal and non-surgical fat reduction. Most recently, Kelly became a certified phlebotomist and is excited to have added PRP treatments to her advanced skincare program. Kelly regularly commits herself to researching and testing a myriad of treatments and technologies in an effort to sift through so much of the junk science we see in esthetics today and bring to Flash Lab a refined menu of services that actually work.



Head Esthetician

Shannon developed an interest in skincare at an early age after struggling with her own cosmetic issues. Seeing the confidence boost that she got from crafting a more advanced at-home regimen, she decided to make her passion for esthetics a career instead of a hobby. Shannon thrives on helping others to discover the same self esteem that she has developed from her years of cosmetic care. Having trained in some of the most reputable spas in the US, she holds certifications in various areas of esthetics including chemical peels, dermaplaning, laser facials, laser hair removal and more. Shannon’s personal philosophy is “Self love isn’t selfish!”

While not everyone may wear makeup or use hair styling products, there isn’t a person on the planet who couldn’t benefit from from a good face regimen. Now more than ever, there seems to be an abundance of popular products, trending treatments and advanced technologies to sift through. After seven years in the esthetics industry, Hope is happy to be able to guide her clients through this often overwhelming field and is a trusted teacher and advisor when it comes to laser treatments, advanced skincare, lymphatic drainage and permanent makeup. Hope moved to New York City to obtain her international CIDESCO license and is proud to now be recognized worldwide for beauty and skincare in over 40 countries and across five continents. Her philosophy on life is the same as her sentiments on skincare: Hope changes everything! We couldn’t agree more.
