Officer G. B. “Greg” Stevens (Ret.)

Garland Police Department

Garland, Texas


Officer Stevens is a recently retired, 40-year veteran of the Garland Police Department, where he served since he started his career in law enforcement in May of 1978. Once graduating from the Police academy, he began his career, as do most, assigned to the patrol division where he spent his first eight years. In January of 1986 Officer Stevens transferred to the Traffic division where he was assigned until he retired in August of 2018. He first went into Traffic as a hit and run investigator, but, by the end of 1986 he was able to transfer to the motorcycle unit, within the same division, which was where he truly aspired to be. Officer Stevens was assigned to the motorcycle unit for nearly 28 years before moving into an enforcement position, in an unmarked traffic car, still in the Traffic Division.


Officer Stevens enjoyed a career that has offered the opportunity for a number of diverse assignments to include various enforcement duties, investigations, training, and a position on S.W.A.T. as a hostage negotiator and ultimately the Team Leader for the Negotiators. Officer Stevens holds a Master Peace Officer license from the State of Texas.


During his career, Officer Stevens received numerous commendations to include two Life Saving bars, two Officer of the Month awards, and the department’s Officer of the Year award. The Garland Police Department also presented Officer Stevens with the Garland Police Department Medal Of Honor for his actions during a terrorist attack that occurred in Garland in May of 2015. Officer Stevens is only the third recipient of that medal since the Garland Police Department was established in 1951.


In 2016, Officer Stevens was invited to the White House, in Washington D.C., where he was awarded the Law Enforcement Medal of Valor  by President Barack Obama in a ceremony conducted in the East Room of the White House. During ceremonies prior to and after the medal presentation, Officer Stevens received greetings and congratulations from a number of highly respected and esteemed dignitaries to include Senators, Representatives, State and Federal Judges, and most notably, the Attorney General, Ms. Loretta Lynch.


Officer Stevens proudly acknowledges that he always worked in a “uniform” division, by his own choosing, because “that’s what being a Policeman always meant to me.” The opportunity to work directly in the community he serves is what Officer Stevens has said has been the most rewarding part of his Law Enforcement career.
