The women behind the work
CO-FOUNDEr, chief clinical officer
Co-founder of Ratio NYC, Kaylyn is a nationally certified Physician Assistant known for her artistic eye, deep expertise in facial aesthetics, and passion for restoring natural balance.

Kaylyn Plum Liebel, M.M.S., PA-C, is an NCCPA Nationally Board-Certified and New York State Licensed Physician Assistant and Co-Founder of ratio NYC.
Kaylyn graduated with a Bachelor of Science in Health Sciences from the University of Florida. She graduated with honors with a Masters of Medical Science in Physician Assistant Studies from Nova Southeastern University.
Kaylyn has 10 years of experience in the aesthetic industry, working alongside top injectors and plastic surgeons in New York City. Kaylyn’s care, attention to detail and artistic eye set her apart, quickly making her the director of non-invasive aesthetics at her UES plastics practice.
Kaylyn’s passion for restoring natural symmetry and volume with injectables such as Botox and Dermal Fillers grew with each client she met. However, Kaylyn became increasingly disappointed by the lack of information, education and personal care in the industry as a whole.
CO-FOUNDER, CEO
Co-founder of Ratio NYC, Lisa left a successful finance career to bring empathy, education, and intention to the aesthetic space, inspired by her own experience as Kaylyn’s first client.
Lisa Graham, CPA

Lisa Subbiondo Graham, CPA, is a Nationally Board-Certified and New York State Licensed Certified Public Accountant and Co-Founder of ratio NYC.
Lisa graduated cum laude with a Bachelor of Science in Business Administration from the University of Florida. She graduated with honors with a Masters of Science in Accountancy from Wake Forest University. Lisa moved to NYC where she pursued her finance career over the past 6 years.
Kaylyn’s first organic botox patient was Lisa. When it comes to something as important and intimate as facial structure, who would Lisa trust more than her best friend? With 80-hour workweeks and a heavy social calendar, Lisa appreciated the power of preventative medical-grade medicine. It was the only self-care routine she found that actually yielded results she liked.
Lisa wanted everyone to feel how she felt after an appointment with Kaylyn; comfortable, knowledgeable, balanced and beautiful.
Lisa left her career in finance to join her best friend in their mission to change the injectables narrative.
The impersonal attitude created an inherent stigma around injectables that prevented clients from taking control of their outer appearance. Kaylyn decided it was time to flip the script and co-found ratio NYC.

OUR STORY
Built on friendship, rooted in intention
Ratio began when co-founders Lisa and Kaylyn (longtime besties) realized something was missing in the injectables space: a more thoughtful, holistic approach. They envisioned a place where education, artistry, and integrity were prioritized just as much as results. From that vision, Ratio was born: a concierge-style, word-of-mouth practice redefining what facial aesthetics can feel like.
