We'd love to hear from you.
Mr. Andrzej is a very nice, experienced and qualified therapist. In the pre-therapy conversation, I told him about my son’s disorder and he gave me more information than the doctor did! Mr. Andrzej is professional, each visit is different and interesting for my son, he is never bored and loves him, and the most important thing is that I can see the results; my son started to communicate better with us since he started therapy. I sincerely recommend Mr. Andrzej!
Andrziej is a phenomenal bilingual Polish speech language pathologist who performs home based speech therapy services in the greater Chicagoland area. He specializes in the treatment of pediatric speech and language delays and disorders and is exceptional at performing speech and language evaluations and assessments. He provides speech therapy for children with articulation and phonological disorders as well as expressive and receptive problems at their own homes. I highly recommend Andrziej as a pediatric speech language pathologist to help children with all of their communication needs.
Words cannot describe how satisfied my family and I am with the Speech Therapy services my son has received from Andrzej Lewandowski. Andrzej is very knowledgeable in his field and it definitely shows in his ability to diagnose and in coming up with different strategies to help his specific diagnoses and needs. Andrzej is very kind, patient, and personable and is amazing at keeping my son engaged by centering therapy around play and across various platforms. My son's speech has progressed tremendously since starting Speech Therapy and continues to do so daily. I know my son would not have come this far if it wasn't for the help and guidance of Andrzej.
As a fellow speech/language pathologist, I have had the pleasure to work with Andrezj in a school setting. He had very good rapport with the students, and used engaging therapy activities. The children always looked forward to working with “Mr. L”! I would definitely recommend Andrezj as a certified, bilingual speech/language pathologist.

He loves going to his therapies. Andrzej is professional, friendly and knowledgeable. I would highly recommend Andrzej Lewandowski.
I highly recommend Dempster Therapeutic Services! They are AMAZING and provide quality care and therapy!
