Excellent representation
I've used leon several times in the last 33 years, for many different things. He has always come through for me, my family, and people that I referred to him on various legal matters. He knows his business, which is so important when it comes to legal issues. I will add always be indebted to his ability to get the job done.

Excellent lawyer
Understands what can be done but also doesn't cross the line into the unethical. We came to him at a very difficult time. He was knowledgeable, realistic and a calming influence.
