MY STORY
An Evidence-Based Chiropractor Who Takes Your Health Seriously
I believe your body has a job to do. Maybe that job is a marathon. Maybe it’s lifting your kids, a full day on your feet or simply getting through the week without pain setting the schedule.
Eight years in the Army National Guard shaped how I practice: show up for the people beside you, and do the work right.
I’ve also been the patient after a car accident. I know how much it means to have a provider who sees the whole picture, thinks about your recovery and has your best interest at heart.
That’s why care here starts with a clear finding, every plan is backed by current evidence, and every detail is handled with care. Whether you’re recovering from an injury, training for something big or want to stay well for decades, you’ll always know what we found, why it matters and what comes next.
I’m honored to be part of your team.

RECOVER · PERFORM · KEEP GOING
Chiropractic Care for Recovery, Performance and the Long Run
Whatever your body needs to do next, care here follows the same standard.
01
Auto Accident & Work Injury Care
Hurt in a car accident or at work? Thorough care, expert clinical documentation, and records that stand up to no-fault and workers’ comp.
02
Sports & Active Living
You don’t have to be a professional athlete to be treated like one. Care from a Certified Chiropractic Sports Physician® for your sport, your workouts, or a weekend with family and friends that doesn’t hurt.
03
Wellness & Ongoing Care
Proactive care for people who want to keep doing what they love, so you stay ahead of problems instead of chasing them.
OUR STANDARD
Doing What’s Right for You, Even When It Isn’t the Quick Fix
This practice is built on ethics and a commitment to doing what’s best for each patient. Sometimes that takes more questions, more detail and more paperwork than people expect.
You have one body and one spine. We take your history, your health and your future seriously. We hope you do too.
What that looks like here
- The right paperwork, done right. Complete records, forms and reports, filed on time.
- Straight answers. Clear information about what we find and what it means for you.
- The right treatment. Recommended because your findings support it, not out of habit.
- The right referral. If another provider is a better fit, we’ll tell you, even if it means your care isn’t here.
If you’re looking for a quick “crack” and to be on your way, we may not be the right fit, and that’s okay. If you want care that’s thorough, honest and built around your long-term health, you’re in the right place.
