Leo received medical training at the Portsmouth Naval Hospital in VA and NMRTC Navy Medicine Readiness & Training Command at Balboa Naval Medical Center in San Diego, CA. He served three tours of duty in Iraq during Operation Desert Shield, Operation Enduring Freedom, and Operation Iraqi Freedom in Battalion Aid Stations as Head Corpsman. Leo received three Navy and Marine Corps Commendation Medals and a Presidential Commendation from G.W. Bush.

Leo retired from the Navy in 2005 after being diagnosed with type 2 diabetes during his physical. He began administering medication at a Methadone Clinic to people addicted to opioids and other drugs for five years while learning to build and troubleshoot computers. By 2013, he was still battling PTSD, his diabetes was out of control, and was diagnosed with kidney disease in 2019. Thankfully he did not require dialysis until September 2021, and he now goes three times a week, which often leaves him feeling sick and drained.

Leo enjoys life with his wife, Mercedes in CA, but misses his active lifestyle of golfing and bowling, and he would LOVE to travel to visit his siblings in Texas!
