Dallas County Misdemeanor Prosecutor of the Year – 2015

Gregg Gallian is a Criminal Defense Attorney at Gallian Firm LLC – based in Dallas, Texas.  Gregg always knew he would become a criminal defense attorney. He appreciated his time at the Dallas County District Attorney’s Office because it taught him so much about trial and about how prosecutors approach cases. He often found himself questioning and challenging motives at the DA’s Office when he was assigned to cases with very little or no evidence. At that point, he knew it was time to make the switch and aggressively advocate for people. He uses the knowledge he obtained as a prosecutor to not just prepare a defense but to also understand and destroy the prosecutor’s case.

Gregg has handled more 50 trials, hundreds of dismissals and received reductions on a countless number of cases. He is a common face around the district attorneys’ offices in Collin County, Dallas County, Denton County, Rockwall County, and Tarrant County.

Gregg has handled some of the biggest and most highly publicized federal cases in the Northern and Eastern Districts of Texas. He is intimately familiar with the inner-workings of federal court and how to best advocate for each client.

Gregg is a graduate of Texas A&M University with a law degree from St. Mary’s University School of Law. He is a family man, a lover of suits, and can make a mean Spotify playlist. Gregg enjoys an active, healthy lifestyle but also held the record at a local IHOP for eating 16 pancakes in one sitting. Balance.

Questions for Gregg

Trial. There is no feeling like cross examination or a passionate closing argument. 

Losing. I’m competitive and it hurts every time.

Yes. I yelled at the Judge and thought I was going to be held in contempt.  I always do what’s best for my clients and if I believe a Judge is incorrect, I feel it is my duty to voice that opinion.  Sometimes louder than others.  They have a lot of options, so don’t copy me. 

I hate chocolate.  It is the worst.  The worst.

Depends, obviously. However, I aim to have every fact of every case memorized. Only then can I do my best work.

I graduated from the business school at Texas A&M. I thought I was going to be a corporate attorney. Turns out, they are never in trial. The courtroom was my calling and once I figured that out, I’ve never looked back.

Assuming it’s a sunny island – 12 pack of beer, snorkel, and a box of cigars.

Schedule a meeting and let’s talk about it. Every case has its own fee.

The Office. We all know a Michael.

Wife and I wake up at 4:30 am where we hit the gym until 6. Coffee and news until 7.  Take my daughter to daycare and then work for the day.  Most mornings I am in court, negotiating with prosecutors and talking with Judges.  I’m in the office most afternoons where I spend time meeting with clients and preparing a defense in their case.  Dinner.  Rest.  Repeat.

I’m an early riser so I fall asleep pretty quickly at night. The eve of trial is always a long night of tossing and turning.

Excuses. There’s something to be said about honesty. I’m a criminal defense attorney – it is all privileged.
