It gives me so much piece of mind knowing I can contact him and get good direction. It is extremely comforting when traveling. And If I need a prescription fiiled he will always help. It helps that he has been my doctor for so long and he has my history. I brag on him all the time. I work in employee benefits so I hear stories

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

He remembers previous health issues I’ve had and follows up to see how I’m doing. He always reminds me to schedule my women’s well check appointments and gives advice on keeping healthy, both mentally and physically. Dr. Stasiewicz has been my doctor for over 34 years…since I was in my mid-twenties, single, and looking for a primary care doctor. Dr. Stasiewicz checked all the boxes then and continues to check all the boxes now. I highly recommend him!

His straight direct speech gave me an understandable recognition for my case.

Checking in was very efficient. Within 10 minutes of my arrival I was in the examination room and five minutes later Dr. Staciewicz consulted with me. He was friendly, professional, and competent and diagnosed my issue quickly and effectively.

Dr. Stas gave me his time and attention very graciously. However, his physical appearance of being in a significant amount of pain and discomfort himself caused me to rethink about selecting another younger, and preferably female doctor at the same facility.

He saw me for less than 2 minutes. I felt unheard. I was supposed to do bloodwork- he did not look at my chart. I wasted my time and want a refund if that’s possible. I will not see him again. Did not address my concern thoroughly

I did not feel good with this visit. Doctors scared me about all the worse things that can happen rather than focusing on diagnosing. I was depressed for a day after this visit.
