From Our Clients

I recommend Mark Allen. I hired Mark 1-6 months ago. Mark handled my Child Custody matter. I’ve worked with Mark twice now and I would never use another lawyer. He was very professional, and always makes you feel like you are his only client even when he’s super busy. Others know you mean business when his name comes up. Couldn’t be happier to have him on my side.

Trustworthy: Excellent

AndrewChild Custody Client

“For clients interested in a negotiated settlement versus litigation, I recommend Mark Allen. Mark provided not only legal perspective on what the law allows, but also creative solutions toward resolving hot button issues while maintaining a respectful, professional demeanor. Mark really hung in and went the extra mile when we hit a road block at the 11th hour. He remained impressively even-keeled and got the job done to everyone’s satisfaction.”
