Mike Tretinjak is executive vice president of growth and strategy at Intero Digital, the full-service digital marketing agency led by CEO Marc Blumberg. Based in San Diego, California, he has spent more than two decades with Titan Growth, the San Diego search agency that became Intero's enterprise marketing division, and now leads Intero's sales organization.
Two Decades at Titan Growth
Tretinjak's career has run almost entirely through Titan Growth, an SEO and paid-media agency. As Titan's vice president of strategy he worked on client strategy, implementation, and research, and his Titan team bio says he had developed and run campaigns across many industries and markets. In February 2012 he co-presented a Titan webinar, 10 SEO Best Practices for Your Website, with Titan president Danny Shepherd and a sales engineer from DotNetNuke, the web content-management software company.
His LinkedIn profile lists Google AdWords and Google Analytics certifications from 2010, and Titan's five straight years on the Inc. 5000 list of fast-growing private companies through 2014.
Titan Growth Inside Intero Digital
Titan Growth later became the enterprise marketing division of Intero Digital, a group built by combining six specialized marketing firms, as Titan's own site describes it. Inside Intero, Tretinjak has held the title vice president of enterprise strategy. The agency's leadership page now lists him as executive vice president and says he leads the sales organization "with the kind of institutional knowledge and client-side credibility that only comes from being in it from the start."
Search Rankings and AI Citations
His LinkedIn headline says he helps companies "combine the power of digital strategies and AI tech to scale and drive revenue," and his recent posts focus on how AI answers differ from Google rankings. Recapping an Intero webinar on SEO, answer engine optimization, and GEO, he wrote: "Salesforce ranks. Doesn't get cited as you would think. Less Annoying CRM doesn't rank. Gets cited constantly. SEO and AI visibility are officially two different games." In 2026 Intero also shared a video of his take on a major Google update and what businesses should do about it.
Outside work, his Titan bio lists coaching his children's sports teams, traveling with his family, golf when he can, and aliens among his interests.
