Amanda Long is a nationally board-certified massage therapist. A champion of integrative wellness and care, she joined ArCTIC in 2018 as its first massage therapist to immerse herself in diverse team of practitioners. Here’s what she’d like you to know about her:

“In 2011, I left journalism to become a massage therapist — trading massaging words for massaging people at The Teal Center for Therapeutic Bodywork, an Arlington institution founded in 1990.

I knew the power of massage to heal first hand, having broken my femur in a cycling accident in 1999. Massage, physical therapy and chiropractic care were essential in restoring my strength and confidence. Bodywork helped me better appreciate and understand my own resiliency and appreciate the process of healing. After 20 years in journalism, I craved a closer connection to others, to no longer be an observer, but a do-er.

And like it had so many times before, massage provided just what I needed. And that’s what you need to know. Massage works. I believe in what I do because I’ve witnessed its effects on hundreds of clients. It’s not an evangelical “You’re Healed” miracle-type transformation. It’s what happens when someone really listens, responds and stays present. Massage therapy exists in that space between science and art. It relies on and is guided by rigorous study of anatomy, pain theory, kinetics and pathology, but it takes creativity and curiosity to tailor it to each client.

So, if your hamstring is screaming at you, I have the training, experience and strong thumbs to lower the volume and find its source.. If your entire body and psyche feel out of sorts because of that familiar cocktail of news, traffic, office politics and childcare juggling, massage can provide a place of calm.

After seven years and thousands of massages, I’ve learned that massage and journalism aren’t so different. My clients tell me their stories — with words, posture, movement — and expect me to respond effectively. Asking questions, being observant, listening and responding to what I see and feel — skills I honed as a writer — have served me and my clients well. As an editor, I thrived on teamwork, harnessing the skills of the entire newsroom to tell a story. I’ve sought to recreate that dynamic by referring clients to and seeking input from doctors, physical therapists, nutritionists, chiropractors and acupuncturists. ArCTIC provides just the environment where collaboration can thrive and you can benefit.”
