Dr. Ahlering is the most knowledgeable, caring, and professional physician I have ever known. He and his exceptional team have been treating me for 16 years extending mylife. We wholeheartedly recommend him 100%
I was disagnosed in June 2021 with Prostate cancer and was referred to Dr Ahlering by my previous Urologist. During my initial visit, it was very obvious to me that he had throughly reviewed my record and spoke very intelligently and with complete compassion and understanding of the situation. I elected to have him perform my surgery and couldn't be happier with him, his office and the care I received. Being in the medical field myself, I recognized that the care I was receiving was top notch and later found many others that recommended Dr. Ahlering, including patients and doctors.
Dr. Ahlering is the Best. His staff was very supportive. Anna his Admin. Assistant was awesome and very helpful. The entire staff and facilities has to be best I the entire Nation!
Dr. Thomas Ahlering is the "salt-of-the-earth". He is professional, classy, extremely knowledgeable and one of the best prostate surgeons in the United States. He spends sufficient time on appointments and does great follow-up on the telephone. Lydia, one of his admin. asst's. is also great with following up and getting Dr. A. to follow-up with you. If you're having a prostate problem...STOP... and make an appointment with Dr. Ahlering.
Dr. Ahlering really doesn’t need any reviews. He is well-known and well respected throughout the community. I work in the medical field and because of that I feel I have become a little picky with the care that my parents receive. Once we got his prostate cancer diagnosis I took to the internet and found his name consistently come up. I was impressed by his resume and his extensive experience. Due to COVID, some of the appointments were done over the phone which worked better for us anyways. We didn’t want to expose my parents (and vice versa) unnecessarily. Lydia and Anne were SO helpful. They gave us their personal numbers and responded very quickly with any questions. All of the paperwork and instructions were very clear. Once the surgery was done, Dr. Ahlering came downstairs personally to tell us how everything went. We were so touched by this gesture and were not expecting it at all. We are so appreciative of all the love and care we received from Dr. Ahlering and his entire staff. If you unfortunately need the care of a prostate surgeon, look no further. We are indebted to him for the health he has given to my father. Thank you Dr. Ahlering
I cannot say enough about the wonderful care and attention to detail I received from Dr. Ahlering and his support staff. Our initial consultation with Dr. Ahlering was one-on-one, performed in his private office. The setting was informal and comfortable. Dr. Ahlering put us at ease with his easy and confident manner and the discussion was extremely informative and inclusive of all aspects of the process and procedure. Dr. Ahlerling's support staff, Lydia, Catherine and Ann are a tremendous asset and provided up-to-date and accurate information throughout the entire process. All of the appointments were on time and efficient. The most important aspect of course is the end result! I cannot be more pleased with the results the surgery. Having researched everything I could find, I had lowered my expectations as to the final outcome. I'm please to report that not only did the final result well exceed my expectations, I was relieved in discovering that many of the ancillary negative side-effects were not present - at least not for me.
Absolutely the best. One of the most skilled prostate surgeons in the world. Innovative-at the forefront of his field. Super intelligent. Incredibly caring. The well being of his patients is his primary concern. Answers any and all questions with compassion. Always does what he says he will do-call you back, return email, etc. His entire staff is unbelievable also. They work very hard to make your experience with them as smooth and pleasant as possible. If you are unlucky and have prostate cancer Dr. Ahlering is the guy to see. You will not receive better results anywhere in the WORLD.
