Listen & diagnose
We start by understanding your pain — its history, what triggers it, and how it limits your daily life. A careful exam and your story guide everything that follows.

How we help
Your path to relief
A clear, methodical process — from truly understanding your pain to getting you back to living.
Pinpoint the source
Using physical exam, imaging, and — when needed — diagnostic blocks and nerve testing (EMG/NCS), we identify what's actually driving your pain rather than just masking it.
Targeted treatment
We treat the source with the least-invasive approach that works: image-guided injections, radiofrequency ablation, or neurostimulation — paired with thoughtful medication management.
Lasting relief
Most procedures are same-day and outpatient at our on-site Burnside Surgery Center — so you spend less time as a patient and more time back in your life.
What we treat
From the source of your pain to lasting relief
We diagnose what's actually driving your pain, then match it to the right treatment — combining carefully managed medication with advanced image-guided procedures. Explore each below.
