“The best words I would use to describe Brad Holt and HSI would be "trusted professional (s)". HSI is professional in every aspect of their business. They recognize the difference between vision and propaganda, and in their relationships they are willing to listen to our ideas and our goals so we can expand our business internationally. We plan to use HSI’s services throughout our growth because it’s hard to find a partner with the international expertise HSI has, and the integrity that makes fast growing companies like ours feel comfortable.”
