Sam Cohen, Certified Advanced Esthetician

As Certified Advanced Estheticians, we go by a myriad of names: Medical Esthetician, Advanced Laser Technician, Skin Therapist, and many more. No matter what we call ourselves, we all share the same goal – to help our patients feel their best in their skin. I feel like I truly have the tools at NW Dermatology to make this possible. Whether I am consulting or in the rooms treating, I strive to make my patients as comfortable as possible and help educate them so we can make the best decision together to reach their desired result.

When I’m not at work you can find me out and about trying new restaurants, venturing around Mount Hood, or spending time with friends and family. I am looking forward to growing alongside NW Dermatology in the years to come!


Riley Wanamaker, Certified Advanced Esthetician

As a Certified Advanced Esthetician, I am educated and experienced in laser therapies, microneedling, chemical peels, HydraFacial MD, dermaplaning, skincare, and other skin/body rejuvenation and resurfacing procedures. My goal through my profession is to not only create long-lasting relationships with clients but to also help patients feel like their most confident selves through treatments in-office and at-home skincare. No matter the situation or concern, I always try my best to make clients feel welcomed and supported.

Outside of the clinic, I enjoy good food, spending time with family and friends, playing tennis with my boyfriend Ryan, and traveling internationally. Since moving to Portland two years ago from Southern Oregon, I am excited about the many adventures to come!

Extremely knowledgeable staff and wonderful environment. Highly recommended!
