I’d had bad experiences with two other Urologists in the past, so when I found myself needing a Urologist again, I was afraid it was going to be more of the same. I could not have been more pleased. Dr. Klein and his staff anticipated every problem I might encounter before, during, and after my procedure, and had a plan in place to mitigate it. What discomfort I experienced was of very short duration. Visits to Dr. Klein’s office were efficient and pleasant. Dr. Klein took the time to answer all my questions, and even answer some I had not thought of. I hope you never need a Urologist, but if you do, Dr. Lonnie Klein will be your very best choice.

I have been a patient of Dr. Klein for over 3 years and I felt compelled to write and acknowledge his wonder bedside manner and medical care. His office staff are very professional, friendly and timely with making appointments and return email and or calls. I especially appreciate the time he spends with me during examines to discuss results of tests. He never rushes thru an examine and answers all questions. He has returns phone calls to me when I have called with urgent questions, which in today world in a much appreciated consideration of his patients.

Dr. Klein and his staff are outstanding. My wife recently had kidney stone surgery. Our faith in his abilities and attentiveness showed his caring nature and his professionalism. Since meeting Dr. Klein and Dr. Richman three years ago, we have never considered changing to any other urologist. When you have this trust and confidence you look no further. The entire staff is caring and listens to the patience questions and concerns without hesitation.
