Why PeeDoc?


We’re Drs. Roscoe Nelson, Howard Tay and Daniel Gilbert. Our practice is formally known as Arizona State Urology but you can call us the “PeeDocs.” Yes, it’s a funny name for urologists in a medical profession with serious conditions like cancer, kidney stones, incontinence, infertility, and erectile dysfunction. However, by keeping things lighthearted, we can connect with more people; and by doing so, we are able to help more people. We love what we do because we simply love helping people. You can always expect honest, personal, and outstanding treatment from our staff and from us. Each patient is unique. Each patient is valuable. Each patient is more than just a name on a medical chart. We will strive to be the urologist you desire.



At Arizona State Urology we understand the complexities of the current medical environment. Information comes at you from many sources including TV, the Internet, advertisements, social media and other sources making your medical decisions even more difficult. We practice the art of teamwork with our Physician Assistant, Anne “Betsy” Hedges, PA-C and Nurse Practitioner, Katie Wall, FNP, as we try to help guide you through these difficult decisions.


The web site is intended to give you more knowledge about urology and related conditions. It’s not intended to offer treatment solutions for your or a family member’s particular medical condition or challenges. Instead, by exploring this site we hope that you will be more informed, and thereby gain more understanding and peace of mind.
