Sometimes it takes a second act to find your first calling. This was the case for Sergeant Derek Nalls, a Texas Game Warden and K-9 Handler who just recently retired after a rewarding 23-year career patrolling and protecting the lands, waters, wildlife, and people of Texas.
Ever since he can remember, Nalls wanted to be a Texas Game Warden, but life ultimately took him down a different path. “When I was 15, I spent my summers and weekends working for my uncle, a home builder. I became really good at it, but before you know it, 20 years had passed,” said Nalls. At 36 years old, he still couldn’t shake the dream of becoming a game warden, and with his wife’s unwavering support, he changed course. “I went back to college for my second degree, this time in criminal justice. I then applied for the Game Warden Academy. On my fourth attempt, I was accepted!”
At 40 years old, Nalls proudly earned his Texas Game Warden badge. His early assignments took him across the state, from Harrison County to Shelby County, and eventually to far West Texas and the Panhandle before he made his final move to Nolan County. Here he embarked on a new mission—becoming a K-9 handler.

In 2013, Nalls was part of Texas Parks and Wildlife Department’s (TPWD) inaugural K-9 team. The first K-9 partner he trained was Woodrow, who was certified in narcotics detection, tracking, search and rescue, and article search. Together, Nalls and Woodrow answered hundreds of deployments, but his most memorable remains the very first time Woodrow located a missing person.
“I was called out to a school to help locate a ten-year-old student who ran away after getting in trouble. I turned Woodrow loose inside the building, and he hit upon a door that was cracked and began barking.” Thanks to Woodrow’s keen nose, the boy was found unharmed, hiding underneath a table. “He wasn’t so happy to be found because I think he knew he was in trouble, but it’s always a great feeling when you find someone alive and unharmed.”
In 2021, with Woodrow set to retire, Nalls began training his second K-9 partner, Skye, a high-energy black labrador retriever who was later certified in firearms detection, tracking, and search and rescue. Together, they completed over 80 deployments, from search and rescue to assisting in border patrol operations and other critical missions.

One of Nalls most memorable missions with Skye was when the pair was deployed to Callahan County to help locate and missing man who had health issues. “Night was setting in, and we needed to find him fast,” recalled Nalls. Skye was able to determine the general direction of the man, which helped Texas Game Warden and Drone Operator Michael Hummert to narrow his search using a thermal drone. Hummert found a heat signature on his second sweep, and Nalls and Skye were able to descend upon the man’s precise location. “He was thirsty and scared, but he was going to be okay, which is the outcome everyone wants in the end.”
As Nalls begins his retirement, he looks forward to spending time with his wife of 34 years, and he plans to take a few cues from his trusted K-9 Woodrow, who has become quite the pro at retirement. “I’m looking out the door, and he is laying in the sun as we speak,” joked Nalls. Skye, newly retired and still full of energy, will also remain by his side as a cherished companion.
“There’s a saying we use in the field—it’s called ‘dropping the lead.’ It’s time for me to drop the lead and let the youngsters take over. I have a boat that hasn’t been cranked in two years. I want to go fishing. I want to hook up the travel trailer. It’s bittersweet, but I think I’ll find plenty to do.”
