Dr. Joseph Welser is a board-certified urologist who provides comprehensive, patientcentered care for a wide range of urologic conditions. He brings a unique background to patient care. He earned bachelor’s and master’s degrees in electrical and computer engineering from Carnegie Mellon University and worked for twelve years in the hightech industry before pursuing a career in medicine. He received his medical degree from the University of Texas Southwestern Medical School and completed his surgical internship and urology residency at the University of Tennessee in Memphis.

Before entering private practice in Arizona, Dr. Welser practiced in Florida and later moved to the East Valley to be closer to family. He spent seven years working at the Phoenix VA Medical Center, where he cared for veterans with uniquely complex urologic conditions. During that time, he helped modernize and expand urologic services, introduced new surgical procedures, contributed to the development of the robotic surgery program, and performed some of the facility’s first robotic surgeries.

Dr. Welser treats a wide range of conditions including stone disease, benign prostatic
enlargement (BPH), erectile dysfunction, and genitourinary cancers. He is experienced in reconstructive and prosthetic urologic surgery, which he finds especially rewarding because it allows him to help patients regain quality of life after trauma, cancer, or other diseases. He is also an adjunct clinical instructor at Mayo Clinic and the University of
Arizona College of Medicine – Phoenix.

In addition to his clinical training, Dr. Welser recently earned a master’s degree in
artificial intelligence from Johns Hopkins University. He uses this background to thoughtfully evaluate new medical technologies and data-driven tools, with the goal of improving care while preserving what matters most: time, clarity, and meaningful communication with patients.

Dr. Welser is compassionate, caring, and down-to-earth. He believes in explaining
medical conditions and treatment options in clear, plain language and taking the time to answer all questions. Outside of work, he enjoys spending time with his wife and three children, visiting national parks, hiking, reading, and exploring new technology
