This is one of those doctors you find and you never want to let go. I only trust my son with him and now they're closing.

Understanding, patient, caring. Gives you a feeling as if you are part of his family. He is very gentle and wonderful with special needs children. I have a son with autism amongst others and from day one, he has been very attentive to my sons needs. He is a blessing.

I had Dr Cieslak when I was young starting out as a type 1 diabetic. One of the sweetest guys /doctors you could ever ask for. Lots of fun and sympathetic . It's been years since I had to switch doctors after I got older
Miss him all the time

We absolutely loved Dr. Cieslak. He was kind, caring, informative and just absolutely amazing! He was so great with my young boys and seeing him was an amazing experience. I left wishing we could see him all the time! Even my son talked about how much he liked Dr. Cieslak.

Fantastic doctor! So helpful, friendly, thorough. I felt like he had all the time in the world to spend with us. He addressed all the concerns we had and did excellent teaching on things we needed to know. I would recommend this doctor to anyone.

We met dr. Cieslak while in the RCH NICU and continue to see him in his office. I cant say enough good things about him. he takes his time with us and is so friendly and knowledgeable.

The best doctor ever! His appointments are usually 30 minutes long. He takes his time explaining everything to the parents. He loves kids and actually takes time chatting up with our boy and gives him stickers at the end of the appointment. He is an extremely busy doctor as he works at the hospital and then does follow ups at the office. It's a little confusing that he shares that tiny office with his wife (Dr. M. Cieslak). With the volume of patients these 2 doctors see, they for sure can afford a nicer and bigger office. You cannot go into their office with a stroller (because the office is so small) so be prepared to leave it in the waiting area. Overall, Dr. Z.Cieslak is excellent and i wish he had more time on his schedule. I usually have to put my son on a call-back-waiting list. They call you back after a month and then schedule you in within 2 months. But the wait is totally worth it :)

Dr. Cieslak is a wonderful Dr. who took his time to discuss my child's issues and really cares about the children he's helping. We met him first while in the NICU and he was very personable and understanding of our questions. He took his time both at the hospital and in his office to make sure our answers were addressed and that we had all information we needed. Highly recommend him!!!!!!
