Why Not?
Hi, I'm Coach Trell.
Behavioral science. Real-world execution. One clear next step.
Jamaal "Coach Trell" Cottrell is a San Antonio executive coach, DISC consultant, and leadership-development facilitator. He works with business owners, executives, and leadership teams to close the gap between the standards they set and the results they get.
Trell has been developing people his whole career, including 20 years in the Air Force training recruits and the instructors who train them, then leading teams through NATO missions and a 63% staffing loss without dropping the mission. He pairs that experience with a master's degree in Industrial-Organizational Psychology, so his coaching is grounded in how people actually behave at work: how they communicate, decide, handle conflict, and perform under pressure. His own Maxwell DISC profile is Challenger (D/C): direct, analytical and built for hard problems. He teaches from that profile, including its blind spot: a strength, overused, becomes the thing your team pays for.
He is a Maxwell Leadership Consultant and Maxwell Leadership Executive Program Leader who delivers the Maxwell Leadership Team Culture Health Scorecard™, a certified DISC consultant, certified benchmark and interview consultant, corporate etiquette and international protocol consultant certified by The Protocol School of Washington, and a member of the Maxwell Leadership Certified Team. He also holds four Boardsi board certificates: Corporate Governance, Board Member Essentials, Cyber Risk Governance, and Strategic Leadership and Innovation in the Boardroom. Digital Reference ranked him #2 among the Best Executive Coaches in San Antonio.
His work spans one-on-one executive coaching, peer advisory groups, masterminds, and team workshops for companies, churches, nonprofits, contractors, and community organizations. Beyond the boardroom, he hosts Silent No More, a platform for men's mental health, and writes for Live From the SouthSide magazine. Read his full executive biography on Leadafi.
