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

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.

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.

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!!!
