Bill Conroy, CPO
Prosthetist/Orthotist
Veterans Affairs
William Conroy CPO
Growing up, I always loved working with my hands. First, it was Legos. Then I graduated to bicycles, then to cars. At the same time, I always knew I wanted to work in the medical fieldâI just didnât know how. After earning my general AA, I was looking through Bachelorâs programs at St. Petersburg College and discovered prosthetics. It was the perfect fit: a way to combine my hand skills with a career directly helping people. Fifteen years later, Iâm still learning something new every single day.
One of the things I love most about this fieldâpatients who teach us, challenge us, and expand our knowledge.
And still, after all these years, nothing compares to the moment when a new amputee stands for the first time. The smiles, the tears, the joyâit never gets old. Thatâs the heart of O&P, and why I feel grateful every day to do this work.
