Certified Laser Technician | Licensed Medical Assistant | Aesthetician
Hi, I’m Marlo Montoya, and I’ve been a certified laser technician for over 10 years. I’m passionate about helping my clients look and feel their best. The most rewarding part of working in aesthetics is seeing the confidence and smiles on my clients’ faces after their treatments.
When I’m not in the treatment room, you’ll usually find me tending to my vegetable garden or spending quality time with my husband and our kids. I believe that feeling good starts from within, and I’m grateful to be part of helping others feel confident in their own skin.
