Founder of Advanced Skin Medspa

Marissa Martínez-Thiele

Marissa is a trusted, sought-after skincare expert and medical aesthetician of the Hudson Valley. She brings over 12 years of experience to the aesthetic industry, working in some of New York City's best medical spas and cosmetic surgery centers. With a genuine and detailed approach to achieving ultimate results for her clients, her dedication to industry perfection continues to draw in clientele from the Hudson Valley to NYC and beyond.

Marissa graduated from the Hudson Valley School of Advanced Aesthetic Skin Care in 2006 and immediately started her aesthetic career in midtown Manhattan at one of the best medical spas. She has since continued her education through quarterly training and certifications. Her constantly evolving knowledge of the latest innovations in beauty -particularly laser- has made her the go-to clinician in her field. As a member of the American Society for Laser Medicine and Surgery (ASLMS) and the Association of Skin Care Professionals (ASCP), her specialty is anti-aging skincare as well as corrective skincare through multiple medical modalities: chemical peels, hydrafacials, laser technology, energy-based devices including ultrasound and radiofrequency, and microneedling and L.E.D. Therapy (light-emitting diodes).

With this knowledge, she trains other clinicians and continues to share the best approaches to medical-grade skin therapies. Marissa feels that no two people are the same, and neither is their skin which allows her to customize specifically to each person's needs. She also has developed a "multiple procedure approach" for her clients to achieve optimal, more dramatic, and longer-lasting results. She loves to educate her patients on "skin fitness" and that their commitment to skincare is long-term, just like diet and exercise. She is also appreciated for her honesty and compassionate approach, respecting her clients' needs, and never steering them wrong. She looks forward to continuing servicing the Hudson Valley as the spa director of ASM for all your skincare needs.

In her free time, you can catch her teaching group fitness classes as her second passion and running after her two little ones, Joshua and Genevieve, with her husband Joshua.
