To do this review in 150 words will be difficult. Before meeting Dr. Gerdisch I met with other surgeons that told me that it didn\'t look good for me and that I was in a bad spot. My girlfriend and I went home and began making plans for my death. At our first meeting the good doctor dispelled all my fears and even did picture drawings so that we understood what was happening. My anuerism was repaired and I received a horse valve. June 30th is our 1 year anniversary. I am on no meds other than an aspirin daily. Thank you Dr. Gerdisch and your wonderful staff! May the Good Lord bless you as you have me.
