At Southern Illinois Associates, we offer Transcranial Magnetic Stimulation (TMS)β€”a proven, FDA-cleared, and entirely non-invasive treatment designed specifically for those who haven't found success with standard medications.

🧠 Why choose TMS Therapy?

Non-Invasive: No anesthesia, surgery, or prolonged recovery.

Minimal Side Effects: Avoid the systemic side effects often associated with antidepressants (like weight gain or grogginess).

Convenient: Sessions are done right in our office, and you can drive yourself home or return to work immediately afterward.

Accessible: Covered by most major insurance plans!

Check out the video below for a quick look at what a comfortable, relaxing TMS session looks like in our office!

We are proud to be featured by NAMI Southwestern Illinois for our work in providing cutting-edge relief for treatment-resistant depression. Our very own Dr. Sanjay Nigam discusses two life-changing options available right here at our Maryville.

At Southern Illinois Associates, we believe "treatment-resistant" doesn't mean "untreatable." Whether it's through these innovative therapies or our Behavioral Walk-In Clinic, we are here to support your journey back to wellness.

This video illustrates the effects of SSRIs, showcasing emotional blunting and the creation of a 'floor' to prevent crisis states. We explore the nuanced experience of emotional numbness and potential medication side effects, including anhedonia and emotional detachment, that can arise from treatment. If you or someone you know is struggling, remember that help is available; call or text 988 for support.

πŸ“’ Exciting News for our Evernorth & Cigna Patients!
We have great news regarding access to Transcranial Magnetic Stimulation (TMS) therapy. Starting March 6, 2026, Evernorth is removing the prior authorization requirement for TMS treatments!

As a contracted provider with Evernorth, we are thrilled that this change will make it faster and easier for our patients to begin their journey toward mental wellness without the delay of traditional insurance approvals.

What this means for you:

Faster Starts: No more waiting for "green lights" from insurance if you have Evernorth or Cigna Healthcare coverage.

Streamlined Care: We can focus entirely on your treatment plan from day one.

Expert Support: Our team is here to help you verify your specific plan benefits and eligibility.

TMS is a non-invasive, FDA-cleared treatment for depression and other mental health conditions. If you’ve been considering TMS, there has never been a better time to reach out.

✨ Are you ready to take the next step? Contact us today to schedule a consultation and see how these new changes benefit your care!

I recently shared a post in a local mental health professional group about a brief educational Zoom session I’m hosting on treatment-resistant depression, including general discussion of where options like TMS and esketamine may fit.

This session is intended for mental health professionals and referring providers and is not designed for patients or family members seeking treatment advice.

If you are a provider and would like to join the professional group or receive the Zoom registration link, please send us a direct message, and we’re happy to share more information.

This chapter is about the quiet part of starting over.

No applause.
No shortcuts.
Just showing up when life feels heavy.

I just released Chapter Two: Starting Over, a short cinematic film inspired by a true story.
