Only Dr. Pienkowski, myself, and the Good Lord knows what we have been through. Nearly thirty years ago, Dr. Pienkowski took me on as a patient for nearly fatal, allergic reactions to honeybee stings. He performed a cutting-edge venom desensitization treatment on me and jumped through hoops to find a hospital that would give him permission to perform the treatment. I would not be alive today without Dr. Pienkowski.

Dr. Pienkowski’s care has been life changing for me. I have highly recommended Dr. Pienkowski to all my friends and acquaintances throughout the years. Whenever I meet somebody with red eyes, sneezing fits, and obvious congestion, I tell them to see my Dr. Pienkowski. Do I think he hung the moon and stars? No, I know God did that. Do I think he is a SUPER STAR? You bet!

When I first came to see Dr. Pienkowski, I was staying very sick with pneumonia and sinus infections. After a thorough evaluation, Dr. Pienkowski diagnosed me with Severe Combined Immune Disorder. With his guidance and under his care, I feel so much better! I highly recommend Dr. Pienkowski to anybody, and his staff has become like family to me.
