@dinom
I am a hospitality-focused commercial real estate broker and founder specializing in hotel investments and extended-stay ventures.
Puerto RicoWhat I'm looking for
I am a Marine Corps veteran and first-generation immigrant who transitioned from residential mortgage work to founding and scaling a hostel business across multiple locations before exiting in 2020. I taught English in Japan, invested in property there, administered a holding company for future investments, and was admitted to Cornell's Executive Master of Management in Hospitality.
Today I lead hospitality-focused ventures and brokerage platforms, managing 1,800+ off-market hotel opportunities, advising on 1031 exchanges, and executing data-driven sourcing and marketing campaigns. I design hospitality standards for flexible, work-ready living, structure CRM and automation systems, and raise capital to scale community-driven extended-stay concepts.
