This entity and its principals are an enigma. I did a pretty extensive search on the CBA website for licensees, and came up empty. The SOS business entity search for this company shows that LegalZoom is the registered agent. The application lists a Phillip Van Dyke at the Devonshire address. This Van Dyke character is not licensed in California as a CPA, so I am not sure what his qualifications are.
I looked at the aerial picture of the listed address, and it appears to be some sort of strip mall, so perhaps this address is only a PMB to receive mail.
I find it suspicious that CPAs do not list the partners or principals on their web site. This is the first site that I have seen where the owners remain anonymous.
Solar Tax Association does not have to be licensed by the CBA if it does not provide any sort of accounting services. So, there must be some sort of arrangement between this alleged consulting side of the business and the referral to the accounting side of things.
Between you, me, and the solar panels, I would not choose to do business with a company that seems to operate in the shadows in a cloak of anonymity. We are supposed to be one of the more upstanding professions (some may disagree). Get your names out there, and have a place of business, not some mail drop.
Maybe someone with better searching skills can find out who they are, where they are, and the name of this accounting firm that is referenced on the Solar Tax Association website.
