Jeff has been in the industry for a while. I've probably known him for around 10 years. He used to work for a larger company that is now defunct (O&A) and started his own MSC after they went bankrupt. They are a small/boutique company, but have some good clients. He doesn't have any of the payment issues associated with O&A, for anyone that worked with them in the past. The Paypal payments always show up without me prompting for payment.
I think the majority of his shops are in So Cal and many are scheduled by an outside scheduler (Frances), so don't be surprised if you get contacted by her in the future as well.
