For over a decade, I taught high school history, earning a reputation as the teacher students called "Sigma" for my no-fluff, real-talk approach to life lessons alongside academics. I specialize in helping students (and adults) build self-awareness, resilience, and independence in a world that often rewards conformity. Beyond the classroom, I'm an experienced writer and ghostwriter with 500+ published essays (AOL, Huffington Post, Substack), a published book, and a track record crafting teacher memoirs, personal growth stories, and self-help books that connect deeply and sell. My voice is authentic and human—shaped by overcoming childhood trauma, professional setbacks, divorce, and personal reinvention. I turn lived experience into engaging, insightful content that motivates without preaching. Currently building The Sigma Teacher YouTube channel (daily videos + Shorts on mindset, school anxiety, and freedom), while open to remote opportunities in education, content creation, ghostwriting, or edtech. Let’s connect if you value depth, storytelling, and real impact.
