Gets the job done
One of the best experiences I’ve had with an attorney, easy-going quick communication follows up in a timely manner does not make promises that are not his to give.

Excellent lawyer and listener
Brent really helped understand my case and triage what needed to happen. There were multiple steps in my case and he let me know what should happen every step of the way. He made this incredibly sensitive and hard time, more manageable. I would hire him again in a heartbeat.

Great Attorney!
Brent was very instrumental in my case and was particularly good at listening to my needs. Divorce is a very sensitive matter and requires someone that understands this and works hard toward a quick resolution. I fully recommend Brent for divorce cases.
