Carl Holden from Zellus Marketing came to speak to our students and delivered an outstanding presentation! Our students either run their own businesses or have entrepreneurial aspirations, so the insights he shared about marketing were incredibly relevant and practical. He introduced us to a new AI platform we were not familiar with and covered a wide range of marketing strategies that our students can actually apply to their own ventures. Carl was engaging, knowledgeable, and clearly passionate about helping the next generation of business owners succeed. We are so grateful for his time and expertise this was exactly the kind of real-world experience our students need. Highly recommend Carl and the team at Zellus Marketing!
