Helping People Build Resilience to Stress So They Can Thrive

Wellness begins with the health of the nervous system. At Spine Body Collective, we use precise, nervous system-focused care to help your body adapt, recover, and function the way it was designed.

We Work With the Body, Not On the Body

The body is intelligent and designed to adapt, recover, and heal. Our role is not to force change into the body. Our role is to create the conditions for change to occur. Through precise, nervous system-focused care, we help reduce interference and improve communication between the brain and body so your body can function the way it was designed.

“We don’t force change into the body. We create the conditions for change to occur.”

The Spine Body Collective Difference

Nervous System First

The nervous system coordinates every function in the body. Our focus is helping the body adapt more effectively to stress and life's demands.

Precision Over Force

Using a specialized approach called Syntropy, we help the body relax before an adjustment is delivered. We work from a position of ease rather than tension. Dr. Ryan is one of only a handful of Syntropy Master Certified Chiropractors in the world.

Quality Over Speed

Every adjustment begins with careful assessment, positioning, and preparation. We take the time to help the body become ready for change.

We were on vacation and my boyfriend’s back went out and he could barely walk or bend over. Our chiropractor back home recommended this doctor to us and they were able to fit us in same day. Dr Ryan was super helpful and you can tell he really cares. He also did the PEMF treatment after the adjustment to speed up the healing. Not all chiros are the same and as someone who’s had chiropractic work for 20 years, I highly recommend this place!

My single word is : Amazing!!! Dr. Ryan has helped my friends and family with his passionate skillset And Therapeutic techniques. My shoulder was stiff and not movable. Likely related to stress, after a sessions of treatment, I was able to begin to raise my arm over my head. I made a small joke with Dr Ryan, that now I have the ability to get arrested lol... We laughed about it 🤣. He's amazing!!! Go see him!!!

I've been seeing Dr. Ryan and Keegan for about 8 years now, and saw Dr. Ryan very often as I'd try to max-out my allowed chiro visits each year back then (work benefit). They are lifesavers, especially when I was working long 12 (13) hour shifts doing super stressful cubicle work. The tension I had was overwhelming. They always made me feel better, especially when I overworked myself and sneezed wrong and threw out my back, I couldn't walk right for days and finally got well enough to (limping) visit Dr. Ryan, the problem went away quickly, this happened twice. I also injured myself pushing too hard outside of work, they definitely, noticeably, and instantly helped with that every time and speeded recovery. I'm no longer doing the cubicle work anymore, but I still work intensely and definitely still need to visit often. It's hard to function without them. The pain relief is real here. I've also had 3 different chiropractors before Dr. Ryan (over the course about another 10 years, cubicle work began early in my life), and he's the best. The other were good too.

I have seen Dr Ryan Ronnenbaum at Spine Body Collective for a number of years now. He has helped me so much with my back and leg pain. I have advanced scoliosis and it causes pain in my legs and other issues throughout my body. He has also helped me recover from shoulder replacement surgery. He is an outstanding Chiropractor who is compassionate and concerned about his patients. He's extremely knowledgeable and has a variety of methods to help with pain. I highly recommend Dr Ryan Ronnenbaum and Spine Body Collective for any of your chiropractic needs.

Keegan is an excellent massage therapist/physical pain relief therapy guru. If you have pain, & something isn't moving like it should, it's likely connected to muscular or fascia issues that needs to be addressed. Pre-surgical, Post- surgical matters not as Keegan will ask what's going on and work a solution. He's excellent at it.

I’ve been seeing Dr. Ryan for over a year now. I came in with bad sciatic pain and neck pain, within a few adjustments I was back to my normal activities and routine! Every other chiropractor I’ve seen has told me I need to come in weekly for that type of pain, Dr. Ryan never pushed to have me come back on a weekly basis and resolved my pain within a month and then I’ve seen him regularly every month since. Even with flare ups, I can consistently feel good for weeks after adjustments from him! He even came in over the weekend this past weekend to help me with my neck pain since I couldn’t turn my neck. I would HIGHLY recommend him and his whole staff to anyone that needs a good chiropractor.

Keegan is awesome and I can't stress enough how talented he is. Was having digestive issues that he has make great stides in. Using the pulse machine for additional healing as well. I've had sessions when I skipped the machine and didn't have as much success as the massage and pulse together.

I injured myself doing bench press. My rotator cuff and shoulder were in debilitating pain. I could not even pick up a glass of water with my injured arm, it was so painful. Dr. Ryan performed shock wave and PEMF treatments that relieved the pain immediately. After 4 treatments the pain was 95% relieved. I can’t say enough good things about how well I am being treated and the results speak for themselves. I will be back for treatment of any soft tissue, ligament and tendon pain.

YOU MAY BE A GOOD FIT IF…
