“My son can talk now!”

I decided to take my son to see Andrzej Lewandowski in Dempster Therapeutic Services after hearing very good reviews from other parents, and I’m pleased with the progress so far. My sons communication skills have improved significantly. We are able to go to the park now and he is not afraid to socialize with kids. What I really like about this therapist is that the sessions are in dual language so he teaches him in English and in Polish and I am very happy about that.

“Best Chicago speech therapy services”

I highly recommend Dempster Therapeutic Services. Andrzej Lewandowski has been instrumental in helping my son overcome speech delays and become proficient in both Polish and English. Their tailored therapy sessions effectively address articulation, vocabulary building, and sentence formation, ensuring comprehensive language growth. We've experienced exceptional results and are extremely satisfied with their services.

“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.
