You don't just want the pain gone. You want back to full speed.

You train. You compete. You've got things you're not willing to give up — the lift, the run, the mat, the field, the trail. When something's off, you don't want to be told to take it easy for six weeks and hope. You want to know exactly what's wrong, fix it at the source, and come back stronger than before.

The method

We don't just crack and go.

Most people have had the 90-second adjustment — same moves for everybody, in and out, back next week. That's not this. We start by actually finding what's wrong: how you move, where it's breaking down, and why it keeps happening. Then we combine precise adjusting with the soft-tissue and technology work that resolves it — so you're not renting relief, you're fixing the problem and building a body that holds up.

An honest plan, with a real endpoint. Not endless open-ended visits.

Everything your body needs, in one place.

Meet Dr. Brennan

Care from someone who's been the athlete.

I'm Dr. Charlie Brennan. I played rugby through college as a team captain and collegiate All-American, then on an athletic scholarship through chiropractic school and professionally with a USA Rugby development team. I know what it's like to want your body back now — not in six weeks.

I found chiropractic as a patient, in a rugby club, which is exactly how I still think about it. I was a founding member of the Life West Sports Performance Institute and worked with the medical teams at AVP Volleyball, Nitro Circus World Games and Dew Tour. I built Peak to be the place I'd have wanted as an athlete: precise, honest, and equipped to actually fix things instead of managing them.

Get you back to what you love — and keep you there.

Where this is going

One roof. Everything your performance needs.

Chiropractic and functional medicine are the foundation — how your body moves, and how it runs. On top of them we're building the rest of what an active body actually needs: recovery, regenerative care, and long-term performance. So you're not driving to five different places to take care of one body.

This is where Sacramento comes to perform, recover, and last.
