Does this sound like you?
You’ve Done the Right Things. The Pain Is Still There.
Most of our patients arrive after months or years of treatments that only managed the symptoms. They come to us because they want the most thorough evaluation available and every non-surgical option on the table before making a decision they can’t undo.
Right now, how much is pain affecting your life?

You’ve tried physical therapy, and the pain came back.
Cortisone shots helped for a few weeks, then wore off.
You’re relying on pain pills just to get through the day.
A doctor has mentioned surgery, or you’re afraid they will.
You’ve given up golf, pickleball, hiking, or travel because of it.
Pain wakes you up at night or makes sitting and driving miserable.
Here’s the good news.
Many of these problems have non-surgical solutions. The assessment helps Dr. Iszler’s team see if you’re a candidate before you ever set foot in the office.
What we treat
Where Does It Hurt?
Tap the spot on the body map. We’ll show you what’s commonly behind it and the non-surgical therapies Dr. Iszler’s team may consider.
Tap where it hurts
PainRelief plan
Back & Sciatica
Bulging and herniated discs, radiating leg pain, numbness, and the low back that never quite recovers.
Four Advanced Therapies. One Integrated Plan. Under One Roof.
Most clinics offer one of these. Your plan combines exactly the ones your case calls for, built from a detailed neurological and structural evaluation.
Tap anywhere to feel a SoftWave pulse
SoftWave Tissue Regeneration
Acoustic wave therapy that stimulates your body’s own repair response in damaged tendons, joints, and soft tissue. Especially effective for knees, shoulders, and chronic tendon pain.
Spinal Decompression
A computer-guided table gently separates the vertebrae to relieve pressure on discs and nerves, drawing water, oxygen, and nutrients back into the disc so it can heal.
Class IV Deep Tissue Laser
High-intensity therapeutic laser that reaches deep into muscle and joint tissue to reduce inflammation and accelerate recovery, without heat damage or discomfort.
Spinal & Postural Rehab
Targeted corrective work and precise chiropractic adjustments that restore alignment and movement, so the results you get in the clinic hold up in your everyday life.

I’ve been seeing Dr. Dave for two months for treatment to my back and foot. Between his adjustments and decompression therapy, I’m feeling significantly better. My pain level is much lower and my range of motion has had meaningful improvement. His staff is great too! Sharee is welcoming at the front desk, and Latoya and Kayla are fun and make decompression treatment pleasant. Highly recommend!

To begin with the staff is absolutely marvelous, they all seem to know their job inside and out. We are greeted by name immediately as we enter the building. Which makes us feel welcome and important. The waiting area is quite comfortable and very quaintly decorated. We are in and out with our appointment in a very timely manner.
