Why Not?

 Hi, I'm Coach Trell.

Military discipline. Behavioral science. Real-world execution.

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.

A retired military veteran from Chicago, Trell learned leadership where clarity and accountability are not optional. He pairs that foundation 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.

He is a certified DISC consultant, certified benchmark and interview consultant, corporate etiquette and protocol specialist, and executive program leader with the Maxwell Leadership Certified Team. In 2026, 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.

If your team knows what to do but isn't doing it consistently, start with a free consultation.
