• Here's a polished version: Dr. Leder is an exceptional physician with an extraordinary depth of knowledge. He consistently provides the most current evidence-based information available and is often able to discuss emerging data that may not yet be widely disseminated when reviewing treatment options, risks, and benefits. His recommendations reflect a thoughtful consideration of the whole patient, including coexisting medical conditions and individual circumstances. Equally important, Dr. Leder is compassionate, attentive, and genuinely invested in the well-being of his patients. He takes the time to listen, answer questions thoroughly, and ensure that patients feel informed and supported throughout their care. His combination of clinical expertise and sincere concern for his patients makes him an outstanding physician.

• Dr. Leder is an absolutely extraordinary doctor! With the vast amount of research about osteoporosis that he has been involved with, no one could be more knowledgeable! But he is also amazingly personable and thorough, several times bringing to my attention important issues that I should bring up with my other doctors! Under his care, my osteoporosis has been downgraded to osteopenia, and he has been enormously helpful with other medical issues as well! I am extremely fortunate to have been under the care of Dr. Leder, and am extremely grateful to him!!!

• I am so glad that I insisted on getting a second opinion from a specific doctor who deals with this specific condition. He was so knowledgeable with what I was looking for information on. Only wish I had all the information he needs so it's going to take longer to complete the ongoing questions I have!
