A search of the Canadian County Clerk records shows that both Dan and Gayla are listed together on several loans including a loan for over $9,000 from Blinds On Budget Inc http://search.cogov.net/Okcana/results.asp
Does anyone know what the story is with Sierra Aviation Inc, and Million Air? Trying to figure out if they have had anything to do with SIOR. It's hard to tell what might be personal or what is connected to SIOR as the company seems to be listed on many of the transactions.
Several of Dan's/Gayla's companies are listed as the Grantee on some of the loans. Apparently, Lloyd's Of America LTD is owned by Dan and two seperate share payments by SIOR have been passed to Dan via Lloyd's. Not sure why they would handle it that way.
Anyway, thanks to Geo for providing the motivation to look around a little. DD on a company that provides no PR's or filings is not the easiest thing and one needs a little push.
The SIOR website lists 844 South Walbaum Road as "corporate headquarters," and both McCoy and Lloyd use it as their address for corporate purposes. Agents and officers often use work addresses, rather than home addresses (although I have no experience in Oklahoma).
The driveway certainly looks more like a work driveway than a home driveway, especially for a mobile home (as you say). Further, your Trulia.com link does not show a number of bedrooms, which is consistent with an office.
So remind us why you think that this address is someone's personal residence?
