Dempster Therapeutic Services

“The best speech therapist for bilingual Polish English kids”

I had the best experience with Mr. Andrzej Lewandowski of Dempster Therapeutic Services. Basically my son was first screened by him, his speech problems were identified. Then I got the "Chicago Speech Therapy" service which basically means my son started regular speech therapy for Early Intervention (private pay, but they do accept HSA). My son started making noticeable progress in 3 weeks!

“We brought our daughter to Dempster.”

We brought our daughter to Dempster Therapeutic Services when she was 3.5 years old. We had initially hoped she would start speaking once she began daycare, but when that didn't happen, we knew we needed professional support. One of the most impressive things was the speed of care—we only waited 9 days for our first appointment, which included a full evaluation and diagnosis.
After just four months of working with Mr. Andrzej Lewandowski, the transformation has been incredible.

“The best Chicago speech therapy clinic”

Andrzej is more than just a speech therapist; he genuinely became an indispensable part of our family. His dedication was unparalleled—he consistently went the extra mile to customize his approach and ensure our son felt supported and motivated.
The progress our son achieved was nothing short of miraculous. Starting from being almost three and virtually nonverbal, he progressed to speaking in full, functional sentences in just 15 months. Today, he thrives in a regular kindergarten classroom.

“Best Chicago speech therapy and accurate diagnosis”

Mr. Andrzej Lewandowski of Dempster Therapeutic Services is very knowledgeable about bilingual speech therapy. Best Chicago speech therapy. My son loves going to his clinic. And the new Schiller Park office is beautiful.

“Good results for speech therapy, beautiful nd clean office.”

I would love to recommend therapy at Dempster Therapeutic Service!
Mr. Andrzej Lewandowski is a great specialist. He establishes an amazing relationship with the child, creates a nice and stress-free atmosphere, and encourages the child to exercise (which quickly brings results). The therapy takes place in very comfortable conditions (the office is clean and beautiful).

“Elite-level speech therapy near Chicago”

If you are looking for elite-level speech therapy, look no further than Andrzej Lewandowski at Dempster Therapeutic Services.
When our son turned two, we hoped that starting daycare would help him develop his speech and catch up, but that didn't happen. Finding the right support became our top priority, and I am so glad we found this clinic. The registration process was an absolute breeze, and I was incredibly impressed that we got our first visit scheduled just 6 days after registering online!
