Dr. John Tis

(Translated by Google) Dr aunt operated on my daughter and I am very grateful to him and I really appreciate that for me he is a great professional (Original) El dr tía operó a mi hija y le estoy muy agradecida y la verdad eso lo aprecio mucho para mí es un gran profesional

Dr. Tis changed my life and continues to support me and my health unconditionally. His team is amazing, and I wouldn't have wanted my spinal fusion surgery done by anyone else.

I was told when I was 4 years old by other doctors I would not be able to run and jump after my surgeries I was allowed to run and jump. Dr Tis understood my anxiety , autism and sensory processing disorder so well during the process. Like I though I had to deal with knee caps moving all the time and poping out .because of Dr Tis he gave me a life I never picture of normal knees and I can run without all the pain his staff is amazing with autism needs

We just love Dr. Tis. He is gentle and very patient. We adore his kindness. He's a blessing from God.

I love Dr. Tis hes always polite professional a thorough. Hes been seeing my daughter since she was in the womb! Literally! Dr. Tis and his staff are amazing!

Dr. Tis seems to be one of the experts for treating our child’s condition. His communication was excellent and he put our son at ease about the procedure. The outcome of the procedure was amazing.

Dr. Tis listened attentively to all our questions and concerns. He took the time to thoroughly explain our son’s situation and the surgical procedures that would treat it. Dr. Tis had great rapport with our son I was very pleased with his detailed explanation about our son’s condition. He took his time in our office visits. I sincerely appreciated his willingness to address all our concerns. He promptly came out to talk with us after our son’s surgery and apprised us of the outcome of the surgery. The follow-up appointments with Dr. Tis have been informative and helpful. I can also call his office with any questions and his personal assistant kindly and promptly gets back to me with Dr. Tis’ answer(s). I would definitely recommend Dr. Tis! He is a highly skilled surgeon and easy to access. He explains medical procedures in layman’s terms. It is refreshing to leave an appointment and feel like all your questions have been answered!

Staff was super nice and doctor was knowledgeable, on time, and thorough.

Dr. Tis is great with my son. He talks to and explains things to him in a way that a 10 year old can understand. Post op Dr. Tis called me himself to check on my son's recovery. The Surgery and the recovery went well.

Very compassionate and sensitive to the specific needs of our daughter who lives with ASD.

Eventually and nice new lady walked over to help as we were about to leave and set us up somewhere else... I DO NOT RECOMMENDED THIS DOCTOR!!!!!!! Had an appointment at his columbia office at 3pm.

Dr. Tis was not gentle with the baby he was checking on (pre-surgery), said baby regularly returns home with fractures after Dr. Tis's rough handling. He was also very rude and rather than informing us of the risks of surgery but leaving us feeling confident, he didn't seem to care. I don't know what caused him to physically treat the baby this way or approach us in this way, but both are completely unacceptable.

Dr. Tis is literally a hoss, fixed my knee up for me.

Dr Tis is amazing doctor at Johns Hopkins. He understands about autism and other special needs issues very well. Made sure I had the best plan for my knee surgery and kept use in the loop on what to expect. He sent us for a CT scan and it prove that it was actually worse than what he though. One night after surgery I had really bad pain and we called him and gave me better pain meds.

Failed to properly study/diagnose my child's complex sports injury (compression hip fracture, CAM FAI, labral tear) before recommending surgery in 2014. Dishonest re his experience w/ hip arthroscopy. Was supposed to repair labral tear he saw on MRI; couldn't find this during surgery, instead did unexpected/unnecessary psoas release also cut healthy cartilage. Result: 1 yr delay in walking, contributing to permanent bone deformities. Needed 2nd surgery w/ different doc to fix original problem.
