TEAM MEMBER Emma Fragapane

MARKETING & SOCIAL MEDIA COORDINATOR

I’ve been a medical assistant for over five years and have always been passionate about helping people feel confident in their own skin. After spending some time in Florida while my husband was in school, I’m grateful to be back in my hometown and part of the Zen team. Since becoming a mom, I’ve come to truly appreciate how important self-care is—not just physically, but emotionally too. That experience has deepened my love for aesthetics and the role it plays in helping people feel their best. I’m also excited to grow with Zen through marketing and project management, blending creativity with care in everything I do.

PROVIDER Angela Barbuta

RN

Since I was a little girl I knew I wanted to be a caregiver in the medical profession. Being the oldest girl of 9 kids, caring for others became a natural instinct. I have been a nurse for over 24 years (the last 6 years in aesthetics) and started my career as a neonatal nurse and in women’s health. After having a family of my own I needed a career that was a little more flexible. I was at a crossroads in my life and took a chance down a path I never imagined in my nursing career. I transitioned from hospital life to stay-at-home mom, to private practice, and discovered a love for aesthetics. There is this incredible unity of science and art in the aesthetic world and I found myself wanting to learn as much as I could and falling in love with it more and more every day. I was not prepared for the strong connection that is created as you walk each person through their personal journey to self-love. I knew I had found where I was supposed to be. I strive to provide individual experiences and educate patients on how each treatment, product, and medication can maintain and enhance your natural beauty. I look forward to coming to work each day! I love to help people in their 20s looking for preventatives, the person over 50 who used to worship the sun, or the ones that just need a little more confidence in their daily lives. There is so much more to aesthetic medicine than vanity and I can’t wait to share it with you!
