five decades of experience. generations of trust.

Cox Bail Bonds is one of Texas’ oldest and longest-standing bonding companies, built on a family legacy that began in 1972. At the center of that legacy is Michael W. Cox, who entered the bail bond profession in 1983 under the mentorship of his uncle and founded Cox Bail Bonds in 1990. What began as mentorship evolved into a company whose name carries weight in courtrooms across Texas.

For more than five decades, the Cox name has been earning the trust of generations of families — standing beside them during life’s most stressful moments. Respected by leading attorneys, recognized by the courts, and relied upon in high-profile, high-stakes situations, Cox Bail Bonds has built a reputation forged under pressure and proven through performance.

Family-owned and operated, Cox Bail Bonds maintains offices in Harris County and Montgomery County, Texas, while providing bond services statewide and nationwide. With our company, the bail bond process can be completed entirely online — delivering discretion, efficiency, and accessibility wherever clients may be.

Visionary Leadership

Michael W. Cox is widely regarded as a visionary, accomplished business professional, and pioneer within the bail bond industry. He represents the generation that built brands through billboards, newspapers, and radio — long before digital visibility became standard — establishing authority through reputation, presence, and results.

Strategic and composed under pressure, Mr. Cox is recognized as both a strong voice and a voice of reason when stakes are high. His leadership is measured, disciplined, and decisive.

His influence extends well beyond company operations. A full member of the Professional Bondsmen of Texas (1995–present), former Parliamentarian of the Harris County Bail Bond Association (2005–2009), the driving force behind the landmark 2008 “Cox vs. State of Texas” victory, and elected to the Board of Directors for the Professional Bondsmen of Harris County Association (2022–present), Mr. Cox does not simply operate within the industry — he has consistently upheld fairness and accountability within the profession.

She is respected for her authenticity, integrity, and steady presence — offering reassurance during uncertain moments. Her bright, positive spirit strengthens both the client experience and the culture of the company.

As spouses and true partners in justice, Ms. Bo and Michael Cox lead side by side, united by shared values and a commitment to serving families with honor and accountability.

The Next Generation

Chris Casto, Michael Cox’s nephew, serves as Company Manager and successor to the Cox Bail Bonds legacy. Since joining the company in 2013, he has trained directly under Mr. Cox as a protégé, developing the operational discipline and strategic mindset required to lead.

Representing the next era, Mr. Casto has strengthened the company’s digital footprint through expanded online presence and strategic social media integration — leveraging technology to streamline operations while preserving the company’s established foundation.

Outgoing, hard-working, and consistent, Mr. Casto has maintained long-standing professional relationships while actively building new partnerships that have driven measurable growth. His leadership plays a central role in keeping Cox Bail Bonds connected, respected, and moving forward in an evolving industry.
