Trevor Larsen, R.N. 

Trevor is a master injector and the co founder of Tru Beauty by Trevor, a luxury cosmetic injectables practice and Med Spa. Trevor has a decade of experience working with injectables, first being PALETTE® trained and certified in 2011.   His many online reviews are glowing and patients praise his bedside manner, attention to detail and his love and care for each and every single person that walk through the doors. Trevor truly loves what he does and is passionate about the art and science of injectables. His motto is that the experience is as important as the outcome – here at our spa, we put just as much focus on making our patients feel good as we do on looking good, both on the inside and the outside.

Trevor was born in Southern Utah and grew up in Sioux Falls, South Dakota. He earned his Registered Nursing degree in Sioux Falls and has worked in the medical field for 15 years in Trauma and Emergency Room medicine, Flight Medicine, Interventional Radiology, Operating Room and Recovery, ICU/Pulmonary medicine, and now exclusively as a cosmetic injector for the past 4 years.

He moved to Las Vegas in 2011 and has been a proud Nevada resident ever since!

When he is not in office seeing patients, he spends his time with his wife, Bella, who is the Co-Founder, Managing Partner and Director of Marketing and Social Media for Tru Beauty by Trevor. They love to spend time with their 4 beautiful children, ranging in ages from 3 to 14. Being in the outdoors, RV road trips, vacations, and lots of family movie nights are some of their favorite things!

Family and Love are #1 to the Larsen’s; Tru Beauty by Trevor is a family owned and operated Med Spa and we want you to feel like one of the family too!
