Hi! This review is going to be about both of Jeff's tours (Salem Witchcraft and Dark Salem) as I've been able to attend both.
I've been visiting Salem for about 8 years now. Fell in love with the city so much that I actually moved here about a year ago. I mention all that to say that I've been on a fair share of tours here. Definitely can't say that I've done them all, but most. And I have to say in my most honest opinion that Jeff has become the best tour in town.
I recently hosted some family who were visiting Salem for the first time, and I wanted them to see some spots downtown and get a better idea of some of the more interesting stories from Salem's past (witchcraft trials and beyond). I also wanted to do a new/different tour for myself as well. And you can just tell how much Jeff loves Salem and its weird history. He's a great story teller, a well of knowledge, and speaks with character and humor. He even told us some stories that were totally new to me (which is nice when you kind of hear the same stories from other tours).
With all of that said, I highly recommend Jeff. Super nice guy, super informative, and well worth your time!
