Nick then went on to completing a Doctorate program in Chiropractic at Palmer College of Chiropractic West in San Jose, CA.

“I love going to work to find what it is your body needs to perform at its best. Is it mobility, stability or a proper training plan?

Chiropractic San Francisco CA Meredith Celeste Meet The Team

Massage Therapist

Meredith Celeste

With more than 13 years of therapeutic massage experience, helping my clients feel better in both their bodies and minds gives me great joy.

I enjoy doing a highly focused, flowing, customized therapeutic massage where I incorporate a blend of well paced deep tissue, detailed neuromuscular trigger point therapy & myofascial therapy, and smooth, relaxing firm Swedish combinations at whatever pressure your body and mind are ready for, while also getting in as much effective pain relief/ body therapy as possible. I move slowly so the central nervous system can acclimate well to the therapy and unwind tensions with ease. I believe the body doesn't need to be overwhelmed to get quality therapy: "good pain" only!

I specialize in both therapeutic neuromuscular pain relief and deep body relaxation and rejuvenation. My massage session has been described as "the meeting place between intensity and grace." I'm passionate about my work and invested in my clients. I prioritize carefully hearing and accommodating my clients' distinct massage therapy needs both before and throughout the session.
