Our Approach

Built on experience.
Refined by precision.

At Active Health, every adjustment, training session, and exercise prescription is built around a simple truth: small moves, done skillfully and intentionally, create big freedom over time.

We don't chase symptoms. We restore how your joints, muscles, and nervous system work together — then teach you to keep it. Movement-first, evidence-based care designed for lasting change.

How It Works

From first visit to lasting freedom

A clear, systematic approach — not a revolving door of endless visits.

01
Step one

Assessment

Thorough movement screening, history, and objective testing to find the real issue — not the loudest symptom.

02
Step two

Treatment

Hands-on care: adjustments, needling, soft tissue work — targeted to your findings. Nothing generic.

03
Step three

Movement

Specific drills and exercises to reinforce what we restore. You leave every session with homework.

04
Step four

Freedom

Measurable progress. Quarterly reassessments. Movement you can trust for years.

Patient Stories

"Damir is the real deal. No sales pitches, no b.s. — extremely knowledgeable and uses evidence-based techniques that can have noticeable and immediate improvement. Coming from someone who thought surgery might be the next step and now would never consider it."

R
Rob H.
Chronic back pain patient

"Dr. Damir is the key to making me a better athlete. I'm a serious runner and on every visit I learned SO MUCH about mobility and specific exercises. I consider my treatments with him the most important part of my training."

E
Erin B.
Competitive runner

"He teaches you about mobility and gives you homework to help improve your spinal health at home so that you don't need to be adjusted as often. He is very knowledgeable and very fun to be around."

D
Daniela N.
Long-term patient

"I've seen multiple chiropractors over the years. This is categorically different. He gave me a report with actual numbers. I knew exactly where I was weak, why it mattered, and what we were going to do about it."

Common Questions

What most people ask first

Answers to the questions we hear before almost every first visit.

What is measurement-driven chiropractic care?
Measurement-driven care means we use objective data — bilateral force testing, limb symmetry scores, range of motion measurements, and heart rate variability — to assess your condition, guide treatment decisions, and track your progress over time. You see real numbers, not just how you feel.
Do you take insurance?
Active Health is a cash-pay practice. We don't bill insurance directly. Many patients use HSA/FSA accounts. We provide superbills for out-of-network reimbursement upon request.
What is the Active Health Performance Lab?
The Performance Lab in Northbrook is our comprehensive assessment space. We conduct 90-minute evaluations using medical-grade force testing, markerless motion capture, surface EMG biofeedback, and heart rate variability measurement to build a complete performance baseline for every patient.
What makes this different from other chiropractic offices?
Active Health combines manual therapy, movement-based care, and objective measurement tools into a single system. Every treatment decision is grounded in clinical findings and tracked with real data. Sessions are one-on-one with Dr. Simunac — no assistants, no assembly-line care.
