    The medical assistant had a great attitude and showed she loves what she does ! The APRN was also very caring and passionate about the care for my child

    Katherine was AMAZING !!! we have dealt with many many lee health Doctors and nurses the past year and a half and sadly she was one of the few that just exuded compassion, empathy, great at listening to our concerns and frustration of a year of consistent chro nic pain. She even said she would reach out to one of my daughters other specialist to work with him WHICH HAS BEEN A PRAYER OF MINE cause I feel it is all related. She even offered to research some stuff and get back to us with it !! She made my daughter actually speak up and take part in the appointment for her health again (which because the way other doctors have made her feel- with no betterment on her condition-) she had given up. She wasn�t crying, defeated or sad when we left which was HUGE in my momma book!!! CARING Enough and LISTENING is the biggest tool for a family to feel supported and not alone; when there are no evident answers or tests results, but pain n symptoms are still evident and present. Thank you!!

    Katherine Oleksak always and I mean always makes my daughter and I feel very comfortable and treat's us as family. She listens and explains everything so we understand. We wouldn't want anyone else unless they were like Katherine. We thank Golisano and Katheri ne for everything they do.

    I have been nothing but impressed with the care we've received. Dr. Oleksak has been pleasant over virtual and in-person appointments, and while Joaquin has while appointments with GI have been mostly precautionary, she has still made sure to we were comfortab le with our sons care and available to answer any questions. Very impressed.
