Eugene has been very essential is shaping my mindset into a hustler, bootstrapper in the world of tech and fundraising. He is very much a grinder and knows insights that not many people praise but have learned just how crucial doing the work on those areas can be. Beyond grateful to have him as a mentor as I learn startups and much more. Cheers Brother (:

Eugene is a real blessing. What I appreciate about Eugene is that he's a mentor but also a friend to you. He's not too rigid but he knows when we need to focus. Another thing I love about him is that he's not telling me what I WANT to hear, he's telling me what I NEED to hear in order to get where I want to be. That's what real friends do. Eugene has a real heart of a mentor and I love him for it.

Eugene is a great mentor, direct and listens to your concerns and doesn't tell you what to do. He provides ideas or suggestions to help you think for yourself and decide what you want to do.
