Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

My family and I went to Dr S back in the 80’s and 90’s. He saved my sister, Mom, niece and my lives. I couldn’t have made it through college without his diagnosis and treatment. I’ll never forget him, and am so glad to see these positive reviews. I could write a book about how he helped us, but this will have to suffice.

Ahead of most doctors in the field. One of the few doctor I have met that actually studies and tries to keep up with the current research.

This is my third time coming to Dr. Steenblock, 1st time was for a non healing wound which we treated with Hyperbaric oxygen, I was healed after just a few treatments. The last two visits were a little more intense as we are now treating the damage left by a stroke I had in 2016. My first treatment last year got me more mobility and I have been walking without a walker for almost 6 months. I am hopeful for more results this time around.

The staff was excellent, very nice, and professional. Dr. Steenblock was very impressive with his extensive knowledge regarding ALS. I am glad I finally found a doctor to treat me who thinks out of the box and is researching everything so thoroughly. I am now confident we can get treat this horrible condition and hopefully get some of my movement back.

My daughter has been a patient for 20 years. in 2014, we went back to his clinic for stem cell therapy. She had a stroke at birth and suffers from CP and epilepsy. They took her own bone marrow twice and gave her umbilical stem cells daily. Fast forward, within 2 months she quit having seizures, was reading for pleasure, got her drivers license and a car and is more developmentally like her peers. Dr. Steenblock is a brilliant and kind man. We will be going back for more therapies.

Stem cell treatments are hard to decide. I think Dr. S. Has many excellent ideas and directions. I know this as I have been to many doctors. I feel that Dr. S. Should continue on this pathway of learning and caring. Thank you.
