Andrzej Lewandowski, MHS, MA, CCC-SLP/L, PEL

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.

Response from Andrzej Lewandowski, MHS, MA, CCC-SLP/L, PEL

Thank you for sharing your feedback with our community.

We appreciate your perspective on our clinical approach!

As a parent with high expectations for our daughter's developmental care, finding Dempster Therapeutic Services has been a game-changer. We travel 30 minutes from Kenilworth each way, and I can say without hesitation that the caliber of care is well worth the commute. What sets this clinic apart is the balance of an elite, sophisticated clinical environment with a deeply personal, boutique feel. Our 2.5-year-old daughter began her journey here with a significant speech delay. In just four months, the transformation has been remarkable—she has moved from minimal communication to speaking in clear, simple sentences. The therapists here don’t just "provide a service"; they offer a bespoke roadmap for your child’s success. The facility is top-tier, the staff is highly professional, and the results speak for themselves. If you are looking for a clinic that mirrors the high standards of North Shore families while providing warm, individualized attention, this is it. We couldn’t be more… grateful for the impact they’ve had on our daughter’s confidence and our family’s peace of mind.

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.

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! As a bilingual family—my wife is Polish, so Polish is our second language at home—it was vital for us to find someone who truly understands that dynamic. Andrzej and his team are fully bilingual, and their expertise in supporting a child raised in a bilingual environment has made all the difference. From day one, Andrzej has been so attentive and kind that he almost feels like part of the family. The interns at the clinic are also wonderful; they are incredibly nice and made the scheduling… process so easy for us. The facility itself is luxurious and professional, providing a calm, perfect environment for therapy. Most importantly, we started regular sessions only two weeks ago and are already seeing major, tangible improvements in our son. It is 100% worth the 15-minute drive to Schiller Park to receive this level of care. We are so grateful to have found Andrzej and his team!

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. As a bilingual speech therapist, he has a specialized gift for connecting with children. Our daughter has gone from not speaking to using words and even full phrases to express her needs! We are still continuing our sessions with Mr. Lewandowski, and it is amazing to see her gaining new skills every single time she has speech therapy. On a practical note, the clinic accepts HSA, which has been a huge help for our family. If you are looking for effective, compassionate, and efficient speech therapy, I cannot… recommend Mr. Lewandowski and the Dempster team enough.

Mr. Lewandowski is an excellent and well-respected bilingual English Polish speaking speech therapist. He is extremely attentive during therapy sessions with clients and he tailors all activities to meet his clients needs and interests. Additionally, he is able to identify any speech delays and areas of concern early on during initial evaluations, where he focuses on using client’s strengths to build up their weaknesses and to increase their engagement during sessions. Mr. Lewandowski’s work helps his clients build communication skills and a strong language foundation to support their successes in school settings and in their future. I continuously am impressed with Mr. Lewandowski’s unique and personalized strategies he utilizes during therapy, and I am very appreciative of the opportunities he has given me to be a part of the therapy process. Additionally, I have seen the positive and rapid progress in clients as a result of the effectiveness of Mr. Lewandowski’s work. I am also… thoroughly impressed by Mr. Lewandowski’s ability to provide accurate referrals to additional specialists and by how quickly he is ready to provide necessary evaluations and treatment for his clients.

Excellent care. An amazing speech therapy clinic near Chicago. Great progress for kids, especially those who are in preschool.

I had a wonderful experience at this speech therapy clinic! Very kind and knowledgeable staff. Best Chicago based speech therapy clinic! Highly recommend.

Choosing Dempster Therapeutic Services was the single best decision we made for our son's speech development. Our experience, which began several years ago, exceeded all expectations, and the results have been truly transformative. We initially chose Dempster based on the strong, consistent recommendations from top professionals, including the Polish speaking ENT, Dr. Hurtuk, and several trusted preschool teachers. Our son was fortunate to work with Andrzej Lewandowski, an exceptional bilingual (English/Polish) Speech-Language Pathologist. Andrzej is not just a 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. It’s hard for most people to believe he ever struggled with speech. If you are looking for a highly recommended clinic with therapists who deliver extraordinary, life-changing results, we wholeheartedly recommend Dempster Therapeutic Services and Andrzej Lewandowski.
