Alicia Gatti, NP
Alicia Gatti is a Board-Certified Adult Nurse Practitioner and the CEO & Founder of modernDOSE. She graduated from Adelphi University with a BS in Nursing and earned her MS in Adult Health Nursing with Honors (Sigma Theta Tau) from SUNY Stony Brook.
She started her career as a Registered Nurse at Good Samaritan Hospital's Ventilator Medical-Surgical Unit, spending a decade building deep clinical knowledge before advancing to Assistant Nurse Manager. From there, she moved into primary care as a Nurse Practitioner, training alongside medical spas and plastic surgeons across Long Island's North and South Shore — and it was during this time that her aesthetics journey began.
After years of watching clients get surface-level treatments while the real issues — hormonal shifts, low energy, weight changes — went unaddressed, Alicia founded modernDOSE in 2020 to close that gap: a Nurse Practitioner-led practice where aesthetics and wellness are one conversation, not two separate appointments. She holds formal certifications from AMET, ESI, and Empire Medical Training, with advanced training in injectables, PRP, PDO threads, microneedling, laser systems, and bioidentical hormone therapy, and is a Certified BioTe Provider. But her story with modernDOSE isn't just professional — it's personal. Alicia has lived the same shifts many of our clients come to us for, which is exactly why she built a plan-based, no-pressure approach instead of a quick fix.
Her journey into nursing was inspired by her grandmother's own nursing career — a legacy that continues to fuel her dedication to compassionate, client-centered care. Outside of modernDOSE, she enjoys spending time with her family and friends, especially her two dogs.
RF Microneedling or Classic Microneedling is a powerful treatment made to reduce fine lines and wrinkles, shrink pore size, and promote better circulation. Used in combination with skin boosters or PRP, this potent skin care solution can revitalize your look, restoring your skin’s luster. Visit modernDOSE today to learn more about this amazing treatment! Many clients pair microneedling with a laser series for even more dramatic texture and tone results.
Smooth texture, fade pigment, and reveal brighter, healthier-looking skin with our advanced laser platforms. Whether it’s CO2 resurfacing for deeper lines and scarring or IPL for sun damage and redness, our Rohrer Aesthetics–certified treatments are personalized to your skin and your plan — the natural next step after your facials and microneedling sessions, not a separate decision.
We offer a range of dermal fillers to meet your needs, addressing facial volume loss, wrinkles, and other concerns at their source. The facial sculpting treatment offered exclusively at modernDOSE combines the power of injectables with fillers to deliver exceptional contouring results.
