What a team. Ran into some trouble a year or so ago because I made the bad mistake of drinking and driving. I hired Mark based on reviews and word of mouth. He and Nathan Beedle worked mercilessly on my case. They are the best criminal defense attorneys in Houston. EVERYONE down at the courthouse knows them and takes care of them. It's not what you know but who you know ;). I'm free, with nothing on my record, and got my case expunged. Thanks to them, I am a free with a clean record. Thank you gentlemen, you both are amazing!!!
