Kasia is terrific at what she does. Well experienced, highly knowledgeable, practical, and very caring. I found her to be a real problem-solver who worked with me to resolve my stiffness and pain. It has now been a few months since I finished my PT with her and I feel better than I have in years. Thanks to Kasia, I have a better understanding of what causes my discomfort and have multiple ways to address it myself. I highly recommend her.

There is no better PT than Kasia. I have been battling cervical vertigo for over 15 yrs. I have been to at least 7 different physical therapists and until i went to Achieve I had no luck. The only thing that helped me was getting steroid shots every 3-6 mos for the past 15 yrs That is until my neurologist said, “ I could no longer get the shots we’re taking it’s toll on my cervical spine. Thankfully, Kasia took a totally different approach to PT than any other PT I have ever been too. Instead of stretching my neck out which is what every other therapist Had me doing, Kasia started strengthening my neck. Giving me all exercises to strengthen my neck. She also started me out slow enough not to cause the dizziness. The most amazing thing that Kasia was able to do was recreate the dizziness in her office and she taught me what to do when the dizziness hit. I am so grateful that we have Kasia, this incredibly talented PT in the Chicago area. I traveled over a 1/2 hour to see her 2 x a week for 8 weeks and it was the best 1/2 hour I’ve spent. Another note, at Kasia office, she has a receptionist, Carline who is terrific. So friendly and kind. So….If you have physical issues that have not been helped in the past then please call Kasia and make an appointment and don’t walk: run!!!…but of course be careful !!! You will be so happy.

Kasia has been my PT for 10 years. She is awesome, she listens to you and knows how to correct your issues and help with the pain. I’m 79 years old have a knee surgery that was botched up, would up with shattered tendon. How I have improved since I’ve been seeing Kasia is amazing. I also have spinal stenosis so I must use a walker. Kasia has helped me with my sit to stand and my balance has improved significantly. Give her a try. I’m sure she can help you too.

There are so many great things to say about Achieve!!! Went here to have PT due to a very painful Torn Meniscus. Ervin, my PT therapist was so patient, kind, caring and knowledgeable in evaluating my pain level and in knowing what I needed to do to improve my condition. Weeks later I am much improved and most grateful for the treatment I received - Ervin.... THANK YOU so much!!

If there were a way to give 10 stars, Kasia would have earned every single one of them. I’ve known and worked with her for over 20 years, through countless musculoskeletal challenges, and she continues to stand out as one of the most knowledgeable, compassionate, and effective physical therapists I have ever encountered.
Living with degenerative disc disease and osteoarthritis from a young age and having undergone multiple surgeries has meant working with many specialists from different schools of thought, but no matter where I’ve gone, I always return to Kasia. She has been a steady voice of reason, a trusted health consultant, and a true partner in my long-term care. Her blend of professional expertise and genuine compassion is unmatched.
What makes Kasia extraordinary is not just her deep technical skills, but her dedication to each patient. She somehow always finds time to take on even the toughest cases and crafts treatment plans that are not only effective but thoughtfully tailored to each individual. Her proactive approach has made a tremendous difference in my life—for example, before my hip replacement surgery, she developed a specialized exercise program to strengthen the surrounding muscles, ensuring that my recovery was smoother and faster than I could have imagined.
Kasia is also a lifelong learner who refuses to settle for “good enough.” Even after more than 25 years in the field, she continuously expands her knowledge and integrates new techniques, always seeking out creative, out-of-the-box approaches that give her patients the very best care available.
If you are looking for a physical therapist who combines outstanding credentials with a deeply human approach, look no further than Kasia and her team. Her expertise, passion, and unwavering commitment to her patients truly make her one of a kind.

I have been very happy with the results from working with Ervin Velic, physical therapist at Achieve Physical Therapy. I had been limited in what I could do because of scoliosis, stenosis, and arthritis.My increase in function has been remarkable. I can cook once again, stand as long as I want, and walk much farther. I recently returned from a 9 day walking tour in Europe that I never would have considered 7 months ago. Thank you, Ervin, for improving my quality of life.

Kasia is an outstanding physical therapist who has been instrumental in my recovery journey from thoracic outlet syndrome, stemming from a car accident. Her expertise in manual therapy, stretching, and strengthening exercises has significantly improved my symptoms and quality of life. Remarkably, she was the first medical professional to identify the underlying issue after nearly a year of debilitating symptoms—her keen diagnostic skills truly set her apart.
Kasia embodies everything you’d hope to find in a physical therapist: she’s knowledgeable, attentive, compassionate, and patient-centered. She has an incredible ability to make you feel like you’re her sole focus during every session, no matter how busy her schedule may be. She takes the time to listen, explain treatment strategies, and ensure that every exercise or intervention is tailored to your specific needs and goals.
Beyond her clinical expertise, Kasia’s dedication and empathy shine through in every interaction. She goes above and beyond, not only in her role as a therapist but as a caring and supportive partner in recovery. Whether you’re seeking help for a complex condition like mine or need assistance with general mobility or injury prevention, Kasia’s skill and commitment make her a standout professional. I can’t recommend her highly enough.

After being told by two neurosurgeons that I needed spinal surgery, I was referred to Kasia by a pain management physician. I am so grateful for that recommendation. I have been going to Kasia on and off for over three years and she has helped me enormously. Prior to that, I had gone to several other PT's but didn't get any significant relief. Recently I developed torn tendons in my left foot and Kasia has helped relieve the pain and improve functioning. It seems there is no end to the various exercises and stretches she has shown me. Kasia is a very caring, compassionate, and knowledgeable therapist. She has worked tirelessly with me to alleviate pain and frustration with my physical problems. I cannot recommend her highly enough.
