About Us

“The one defining characteristic that makes a security provider different from all the others is local management. No matter the company, you are only as good as your local management.”

Ryan Green

In mid-2018, J. Ryan Green and Jason Hamilton began a conversation about the state of the security officer industry in the United States. What started as an interesting discussion on the consolidation of the industry among a handful of very large security companies, a simple idea sprouted: What if Ryan and Jason used their respective experience in the security services industry and in business operations together, and did it better… again? From the simple goal of hiring the best officers available in order to provide excellent security officer services and solutions, Horizon Security was born.

To that end, we provide a brief biographical history of key Horizon ownership and management personnel.

Ryan Green

President & Managing Owner

Mr. Green is a native Floridian who returned to Texas in 2018, where he had first attended college earlier in his career. Ryan is Horizon’s President and Managing Owner, handling the day to day operations of the company along with its growth plan. Upon teaming with Jason Hamilton, former President of ALERT Protective Services, Horizon Security’s start in Dallas gained traction with clear ideas on how the company would grow and the quality service it would offer. 

Lubbock Christian University, was where Ryan got his first taste of Texas life. After returning to Florida several years later, Mr. Green transferred to State College of Florida while also attending the Law Enforcement Academy in the mid 1990’s. He received Dean’s list honors at SCF, and graduated in the top 5% of his class at the Law Enforcement Academy. Ryan was hired by the Manatee County Sheriff’s Office in 1997 and served as a Patrol Deputy and a Property Crimes Detective until 2001, when he made the decision to enter the security services industry because of its potential for growth.

After leaving the Manatee County Sheriff’s Office, Ryan became the Branch Manager for Allied Protection Services in Orlando, Florida. Based in Fort Myers, Florida, Mr. Green grew the Orlando Branch from virtually no revenue as an upstart branch, to a multimillion-dollar branch in under 12 months. Upon relocating to the Sarasota area in 2007 to be closer to his family, Ryan was hired as Branch Manager for the relatively young ALERT Protective Services, also based in Sarasota.

Upon joining ALERT, Mr. Green and Mr. Hamilton worked together for the first time and developed a mutual respective for each other’s specific talents. While at ALERT, Ryan managed contract security guard services for upscale homeowners’ associations, high rise condominiums, office building complexes and distribution centers. It was during this ALERT tenure that Mr. Green learned how to manage quality accounts and provide the best customer service available in the security industry. ALERT’s focus was to hire the best people and match them with the positions where they will excel, with the ultimate goal of winning its customer’s loyalty “for life”. Ryan honed his customer service and sales skills and later became the Area Manager for a national security company, Allegiance Security Group. Ryan grew the Allegiance operation in Sarasota for several years prior to leaving to start his own company in 2010.

In the eight years, prior to his relocation to Dallas, Ryan started and operated his own Private Investigation Agency in the Sarasota – Bradenton Area, J Ryan Investigations. Mr. Green successfully managed other private detectives and field personnel while also working several high-profile cases himself, including the Katelyn Markham murder case out of Ohio, partnering successfully with Ms. Markham’s family and law enforcement to move the investigation forward.

Mr. Green has 20 plus years of security, investigations, law enforcement and management experience that he brings to the Horizon team for the benefit of its clients and personnel. Ryan is a Licensed Security Firm Owner and Licensed Manager with the Texas Department of Public Safety.
