Massage by Nicole Tilson, LMT

We live in our bodies 24/7, and experience the world through our bodies, yet rarely do we have the chance to simply relax and experience our

bodies through compassionate touch. As a client of Dr. Lenarz, I understand that receiving bodywork, much like dealing with chronic pain, can be be an emotional time for some, as the body goes through many changes that impact daily life. I invite you to enjoy a session with me to find comfort, relief, escape, or a chance to simply notice your body.  My goal for every session is always to meet my clients where they are, to listen intently.

I attended Discovery Point School of Massage in 2018 and simultaneously studied LomiLomi-inspired massage, and later studied Thai massage at the TMC School of Thailand. A typical massage from me generally includes long, relaxing, heel-to-head strokes, broad heavy pressure, and intuitive muscle-specific work. I also can incorporate Thai stretches, myofascial work, passive movement, neuromuscular techniques, and gentle oscillation of joints and muscles.

I am constantly learning from my clients and I encourage you to guide me toward the techniques that will be most effective for you. I strive to make each massage as unique as the individual I’m working with, and I sincerely look forward to working with you!
