I guess the first thing I should do is explain my name. My full name is William Joseph Shaw IV. My parents weren’t too fond of any of the usual nicknames like Joe, Will or Bill so they got creative. They took the “Jo” off of Joseph and were left with Seph. That’s what I’ve always gone by and it’s the name I’ll answer to quickest. I am a native of Fort Worth and grew up on the southwest side of town. I attended All Saints Episcopal School K-12 and played sports throughout high school. I received my bachelor’s degree in biology from The University of Texas at San Antonio in 2002. I received a master’s degree in physician assistant studies from The University of Texas Medical Branch at Galveston and passed the Physician Assistant National Certification Exam in 2005.

My name is Mike Sangenito and I am an orthopedic surgical Physician Assistant with experience in orthopedic trauma, sports medicine, and joint replacement. I graduated from the University of Arkansas, magna cum laude, with a Bachelor of Science in Exercise Science. Shortly after completing my undergraduate studies, I entered the Physician Assistant program at the University of Arkansas for Medical Sciences, and graduated with honors, earning a Master of Physician Assistant Studies in 2020.
Following graduation, I accepted a position with a busy orthopedic practice in Houston and gained invaluable experience working with orthopedic trauma, and sports medicine patients. During this time I developed a deep interest in patients who are dealing with acute injuries and developing a patient-centered treatment plan best suited for them.
2020 was a wonderful year for me because my wife, Hannah, and I were married, and I was blessed with a position that provided me with a great experience. And now we are very grateful to be moving back to the Fort Worth area, where I was raised. In our free time, we enjoy staying active, lifting weights, hanging out with family and friends, and watching the Dallas Cowboys and the Arkansas Razorbacks.
