Advance Guitar Training in LA

Hi, I’m looking for recommendations for a guitar mentor or tutor who can help me develop advanced guitar playing techniques.

My goal is to play fast yet with freedom, improve my accuracy, and write original music. I admire the shredding styles of John Petrucci and Paul Gilbert, and I want to build skills similar to theirs or anything close to that level of playing.

If there’s anyone in the Los Angeles area who can mentor me and help me advance my current skills, I’d greatly appreciate your suggestions. Thanks!
