I have a 1st brown in DZR and studied under Herb LaGue.
Avoid him. He used to be highly placed in the AJJF but left/was kicked out. Many of his students left him because of his behavior.
I strongly suspect that he and his wife are long time amphetamine users. I know he is a weirdo from personal contact with him over a few years of classes. Imagine someone along the lines of Charles Manson/Jim Jones/cult leader personality. He was so weird that I left theAJJF for almost 10 years to avoid him. I came back when I heard he and the AJJF had parted company.
Frank Ferris at High Sierra Jujitsu, however, is a great guy, and I cannot recommend him highly enough. He and his wife Cindy are great. They hosted the convention this year and I spoke with them personally.
I hope this helps.
