Dennis is still quite active as an eBay seller although his health could be better. This link will take you to his eBay store:

Since selling the
Vintage & Classic Baseball Collector magazine, he has written three (possibly more) books and still resides near Tacoma, WA area where he held the largest of his PNN shows and published
VCBC.
As others have said,
VCBC was an outstanding periodical and Dennis a talented fellow.
