    Dr G is a kind and caring physician. He truly cares for his patients and arms the parents with knowledge to continue the care at home. There are not enough words to say how much our family has learned and benefited from having Dr. Gruczynski as our Pediatrician!!

    Talked over me and didn’t really listen. Was condescending and interrupted to ask his question again if I didn’t answer the way he wanted. No bedside manner at all. Clearly a knowledgeable and competent doctor, but I wouldn’t ever see him again.

    We love Dr. G. He is patient, kind and takes his time taking to my kids. He is thorough and makes sure he doesn’t just talk to me as the parent but, speaks to the kids as well.

    He has been my kids doctor for many years! My boys now that they are older are always devastated they cannot go back to Mr. Gruczynski he simply is one of the best doctors in the area and one to remember. He is doing gods work and my boys and daughter are one of many other people who were taken care of in such great hands. Thank you Tomasz Gruczynski and all the staff there!
