Who is Justin Mark O’Brien…

Justin Mark O’Brien (his friends call him Mark or “JMOB”) started his entrepreneurial lifestyle and gained his great work ethic at a young age while growing up and working on his family farm in Nebraska.

In 2004, Mark started his college years with an internship at Walt Disney World in Orlando, Florida. While at Disney he received a full semester of “Fortune 500 Customer Service” training courses and hands-on experience at Chef Mickey’s restaurant; even winning the yearly coveted “Guest Service Award”.

During college, he majored in Systems Engineering, while working full-time with the Nebraska Husker Football team and the University of Nebraska housing as a Resident Assistant. Mark went on to train 120+ University of Nebraska resident hall front desk workers in customer service for three years during college. In 2005, after taking coding courses, Mark taught himself other web coding languages and SEO (search engine optimization) during his spare time in college. He would research niche keywords, develop affiliate marketing websites around them, then flip them for a profit; this process helped eliminate all his college loans before graduating! He also launched his ad agency at this time to begin helping other businesses with their online marketing.

In 2008, Mark graduated with honors from UNL and took an internship with the Chicago Cubs where he won the 2009 “Employee of the Season”. While working full-time at Wrigley Field, Mark launched a commercial/TV production company to pair with his digital marketing agency.

In 2010 he moved his company to Los Angeles. Mark has pitched and optioned shows to TV networks including Discovery, Comedy Central, TBS, Spike, VH1, GAC, LOGO, G4, NBC, TLC, CMT, MTV, truTV, and Bravo. While working freelance television and film positions in Los Angeles, Mark continued to develop and build various web applications and started multiple successful online businesses including an internationally distributed wedding band line and a charitable marketplace (acquired in 2014). In 2014, Mark launched Coursenvy.com, a top rated online courses provider (with 200,000+ students by 2019). In 2014, Mark finished as a top 8 finalist for the Entrepreneur magazine “Entrepreneur of the Year“.

Mark is a huge Husker Football fan! He loves watching all types of movies and standup comedy. His pastimes include studying/reading about marketing, real estate investing, stocks, human development, life hacking, and start-ups. Every chance Mark gets (whether it be while driving, hiking, biking, or working on his laptop) he has an audiobook or podcast playing! He has a huge family in Nebraska and is an uncle to a gaggle of amazing nieces and nephews!

Mark is currently angel investing in other entrepreneur’s businesses and growing his digital ad agency.
