Evy Ramos

Microblading Artist

Evy Ramos is a certified and licensed cosmetic tattooer servicing Philadelphia and surrounding areas. With a sincere passion for effortless beauty, inspiration from makeup trends, and motivation from music, Evy has always had an affinity for shape, color, and form. It is with this admiration and natural talent that it resulted in her love for permanent makeup.

Evy began her Microblading career in June of 2016 in her previous home city of Chicago, with a background in tattoo shop management. She relocated to Philadelphia by December of 2016 and has been here ever since. She has taken multiple certification courses over the years and continues to pursue any imperative training in permanent cosmetics. Additionally, she is bilingual in English and Spanish.

Gail McArdle

Practice Manager

Like the Gemini that she is, Gail has had her hands in just about everything we do here. She’s played the role of Administrative Assistant, Licensed Aesthetician and Patient Care Coordinator, so it seemed only naturally fitting that her next role be Practice Manager. She’s a natural problem solver and loves finding ways to organize a messy space.

In her opinion her biggest accomplishments so far in her new role would be designing our new logo, hiring this rockstar staff, and being much funnier than Dr. Subbio.

Her love for Subbio Plastic Surgery runs deep and she is so happy for the opportunity to help our practice continue to grow and flourish.

Staci Kelly

Administrative Assistant

Staci is one of our administrative assistants and considers herself the resident office technological problem solver. There is no question she will leave unanswered/unresearched and loves to learn new things. Staci graduated from West Chester University in 2008 with a B.S. in Elementary Education and has plans to return to school sometime in the near future. When not at work, you can find her involved in one of her two biggest passions: reading books and running.

Zoe Popowcer

Scheduling Coordinator

Zoe has been in the aesthetic field since 2012 after graduating from Jean Madeline as a licensed Aesthetician. She started her career as a laser technician working with everything from Fractional to designing custom facials.

She is the first friendly face you see to welcome you into our practice and she will go above and beyond to make sure your appointment is a wonderful experience from start to finish.
