Are you or a loved one struggling with Treatment-Resistant Depression (TRD)?

It can feel isolating when medications haven't worked. But you are not out of options.

We offer Transcranial Magnetic Stimulation (TMS), a safe, FDA-approved treatment that is proven to be more effective than switching antidepressants for those with TRD.

Why consider TMS?

✅ It's Not Medication: TMS is non-invasive and uses gentle magnetic pulses.

✅ Proven & Effective: It directly stimulates the brain's mood-regulating areas.

✅ No Downtime: Return to your daily activities right after your session.

Our compassionate team at Southern Illinois Associates is here to answer your questions and guide you.

Take the first step toward relief. Contact us for a confidential consultation.

Do you ever find yourself procrastinating, feeling anxious, or riding emotional highs and lows? You’re not alone.

Sometimes, these struggles are just part of daily life. But other times, they can be linked to conditions like ADHD, anxiety, depression, or bipolar disorder.

We’ve put together free, easy-to-use screening tools to help you check in with yourself. These aren’t diagnostic tests, but they can give you a clearer picture and show when it might be time to talk with a professional.

Because mental health matters — and sometimes the first step is just checking in. 💙
