Hmm I have never heard of him. I would be leery of anyone who offers a free workshop designed to convert attendees to the next level, a fee-based multi-day event. You may then learn that there's a next level after that - one on one mentoring perhaps? - that will cost more. And I'd be dubious of anyone who promotes a proprietary real estate investing "system" since that just perpetuates an expensive guru dependency. So you are right to be skeptical and ask around.
The BP podcasts are an incredible source of information and confidence for new investors - I listen on my commute, how efficient is that - and you'll get a sense from listening to the interviewees who is reputable and who is not, and the various approaches out there to wealth building.
If you are set on a particular person, you may want to learn as much as you can about his investment record, how long he has been investing, what sort of returns he's created, what folks are saying about him, and has he been sued, etc. The web is a great place to start. It's great you are taking action; best of luck.
