Our Experts
Melissa O’Mahony
Owner, Director of Operations
Owning a medical spa has been a great joy. It’s not just a business; it’s a platform to help other women feel confident and empowered in their own skin. Seeing the transformation in our clients—both inside and out—is truly rewarding.
I’m fortunate to work alongside a team of incredibly talented, educated, and kind women whose dedication and passion bring so much life to our MedAesthetics practice.
Beyond work, my life is grounded by my four children who are the light of my life.
I also find balance through working out, entertaining friends and family, and riding on my cruiser bicycle.
Running a medical spa has not only been a dream come true but has also allowed me to give back to causes close to my heart. Through our success, I’m able to support charities that focus on helping women and children of all ages, something I’m incredibly passionate about.
