Dr. Stahl recently joined the Columbia faculty practice (came from Cornell), and I was thrilled to get an appointment with him. His reputation as one of the leaders in the field on reproductive and sexual medicine preceded him. I was worried I would have a long wait for an appointment but I was able to get in quickly. He did not disappoint. He is warm, approachable, exceedingly likable - and, most important, a phenomenally knowledgeable physician. He is at the cutting edge of his field and it shows - he knew immediately what my problem was and has started treatment for what has long been a troublesome problem for me. I am so glad I found him and I recommend him to anyone who wants to see a true expert in the field.
