Dr. Klein is a very thorough and caring surgeon. He can be a bit gruff but don’t let his manner fool you. He takes a lot of time with each patient to be sure that they fully understand all of their options and the pros and cons of each. He encourages you to ask questions and actually listens to them and takes the time to hand write everything out for you so you have the information later to refer back to. Because of this, he is usually running behind on appointments, so expect to wait. Don’t worry though, it is worth it. I am extremely happy with the results of my Roux-en-y Gastric Bypass and (two years later) Hiatal Hernia Repair and Abdominal Wall Reconstruction. The follow-up care after both surgeries was excellent. He expects the best from not only himself, but his staff and everyone else involved in your care.
