Dr. Greist is great! She and her PA Laura always spend as much time as I need. They do a great job!

I knew at our first visit we were in the right place and instantly felt more at ease knowing I had them on my side helping with my toddler's condition.

Couldn't ask for a better hematologist. Dr. Greist is amazing and has been a lifesaver in so many ways.

Anything I have needed they have been able to help me with. I do not know what I would have done without them over the years.

I am thankful to have them ... as I navigate my son's hemophilia ... I would definitely be lost without all the doctors and staff that treat my son!!!

My case isn't common and I have had amazing care from everyone at IHTC, especially Dr. Hardesty and Laura PA. Thank you all for not giving up on me.

- Pam B. -

I ended up relapsing prior to my first scheduled appointment with Dr. Hardesty. I met him for the first time in a hospital room, very ill. Since that day, I've never had a second thought about switching physicians.

- Rhiannon S. -

Dr. Bakeer and all of the staff are excellent, caring and top notch. Many health facilities should take a lesson from this facility.

Always there for their patients. And very caring and helpful staff. Couldn't be happier with the way they care for my son.

I can’t tell you how good it felt to see that symbol on your coat, because it meant finally … someone knew what was going on.
