I was also a victim of Frank's con. Agave Custom Homes took my family for a large amount of money, unfortunately. I tracked down some of his vendors and they told me Frank and his family have a history of misappropriating and sometimes outright stealing customer deposits. I was told that Frank is on the run from creditors and he has multiple complaints filed against him with the AZ Board of Contractors. Every few years Frank changes the name of his company (Stephanie's Cabinets, Downtown Cabinets, etc.) as people catch on to his fraud.
He posts multiple ads on Craigslist - be careful. He will bid you a great price on a job and then ask for a 50% deposit. Months after we gave Frank a deposit (and each week a different excuse from Frank) he brought over some poorly constructed furniture to our home to finish assembly and paint. Frank showed up with one of his workers with gang tattoos who did not speak English and asked to leave this worker at our home while he Frank left for the day. Scary is an understatement. When Frank completed our entertainment center and other furniture we had to have another vendor rip it out and start over as Agave's furniture was uneven, shelves misaligned, mismatched paint/stain - - totally amateur work. AVOID!
P.S. not sure why Yelp shows me as being in San Francisco. I live in the Southeast Valley of metro Phoenix. Agave Cabinets operates in the metro Phoenix area.
