I had my first appointment with Dr. Stasiewicz today, and I couldn't be more impressed! From the moment I walked in, he made me feel like a valued patient rather than just a number. He took the time to thoroughly explain my condition, which turned out to be different from what I initially thought. I really appreciated his approach—he didn't just give me a quick diagnosis; he provided clarity and relief, ensuring I understood what was happening with my health. To further ensure my well-being, he arranged for me to get some X-rays done. One of the highlights of my visit was when he walked with me to his office to enter my pharmacy contact details for my prescription and the X-ray order. His considerate nature and personal touch made a huge difference. I highly recommend Dr. Stasiewicz to anyone seeking a kind, knowledgeable, and thorough physician. His honesty and willingness to explain everything truly set him apart. Thank you, Dr. Stasiewicz—you have a new patient for life! Lupe Lambaren

Dr. S is kind, patient, informative and truly interested in his patients. I have a complicated medical history and he didn’t blink an eye at knowing what to do next and respected my knowledge about my own conditions. He is a wonderful doctor and person! Not to mention good staff is AMAZING! Just as kind and interested as he is. Very happy I found him and his team!
