Dr Kovaleski is one of the best surgeons I have encountered. He was recommended to me by my GYN for something I had never heard of, Pelvic Vein Congestion Syndrome. From my first appt with Dr. Kovaleski - he made me very comfortable with the procedure and explained it in a very clear and easy to understand way - with a drawing! You can tell from the staff, nurse practitoner, medical assistant interactions they are all happy with where they work and take pride in what they are doing.

Dr. Nutting is just a great doctor and I would highly recommend him to anyone!!

I had BPH, (Benign Prostate Hyperplasia - also know as an enlarged prostate). The only option presented to me by my Urologist was a TURP. Based upon my research, the complications of a TURP are significantly under reported. Thus, I was looking for another solution - while my BPH symptoms continued to get worse and the symptoms harder to control.

Dr. Nutting is one of the few Interventional Radiologist in the USA who is preforming the Prostate Artery Embolization. I contacted his practice and was immediately connected to a receptive and responsive staff. I forwarded my information and found out I was indeed an excellent candidate. I made the arrangements and later flew from San Jose to Denver for the procedure.

The procedure went extremely well!! I am delighted with the results. My BPH symptoms are greatly reduced and quite easily managed. I would recommend this procedure to any man who has BPH symptoms.

I can't say enough good things about this procedure, Dr. Nutting and his staff. By all counts an elegant procedure and process.

Thank you Dr. Nutting and staff!!
