It looks to me like a self-publishing operation that's expanding. Mr. Allen published his earliest book, Change of Heart, through Xlibris. The covers are very unprofessional-looking (to me, anyway) and I wonder, as I always do with people who self-publish, how much knowledge there is here about book marketing and promotion. Also, sometimes the return arrangements that little publishers offer are so restrictive that bookstores don't find them attractive.
I know I probably seem hard on little hobbyist publishers like this. But they are (literally) a dime a dozen these days, and with most of them, you probably would get a similar amount of exposure by printing your book at Kinkos and handing it out on streetcorners.
Many really stinky publishers are members of PMA. Not saying that PMA is bad--in fact, it's a great organization for its members--but membership is irrelevant to professionalism or legitimacy.
