    Back in the late spring of 2008, I had a minor medical condition that required some surgical…read morecondition. I mean, I know most people grow football-sized tumors in their spleens...right? *ahem* Well, regardless, I needed a fabulous doctor to kind of nip that one in the bud before it became soccer ball-sized. Dr. Allendorf is both a professor at Columbia University's College of Physicians & Surgeons and an attending surgeon at NY-Presbyterian's Columbia University Medical Center. He specializes in liver, pancreas, and endocrine surgery. I'm honestly not sure where "spleen" falls in those category, if at all, but Dr. Allendorf kindly took me in and fixed me up all shiny and new. He is an extremely kind doctor and very straight-forward about what I was dealing with. He is soft-spoken and I felt extremely comforted by him. While hospitalized, he would check on me on occasion, and he was very thorough with his post-surgery follow-ups on me. As a current employee of NY-Presbyterian, I do see him on the rare occasion I am doing work in the ORs or PACU areas at CUMC. I even see him eating lunch sometimes outside of the Sage cafeteria. Perhaps, one day, I will actually have the nerve to walk up to him and say thank you. I will refrain from lifting up my shirt to show him my scar and exclaiming, "Remember...THIS?!" I try to have SOME class while at work. ;-) But in all seriousness, he is a fabulous doctor. I highly recommend him. As a possible future patient, you will be in skilled and competent hands. (I mean that quite literally as well as figuratively.)
