Staying power

Bryan has helped me through a very stressful divorce and post divorce legal situations.

Outstanding Attorney Representation

Bryan knows how to represent you against bully ex-husbands. Without his legal support, I don't know how I could have ended up in court. Bryan was always clear to me from the beginning on how things would play out and apply the best legal strategy for my case. I was impressed with Bryan's communicat...ion skills. Look let's be realistic, Attorneys are not cheap, and some of them make money by giving you the round around or by creating more problems for you. Even in the toughest times, Bryan spoke to me with honesty and the respect that I deserved. I never thought that I was going to face this nightmare of custody and child support battle. Thanks to Bryan Sullivan for his outstanding representation, I hope that my ex thinks twice before messing with me again. Thank you, Bryan Sullivan

Fantastic Representation!

I couldn’t be happier! Bryan helped guard mine & my child’s interest CLOSELY in family court. If I ever need help in this arena again, I know who I’m going to!

Among the top attorney's in the area

I was fortunate enough to be represented by Bryan in a complex divorce/child jurisdiction trail this year. The elements of the case were complex in nature. Bryan immersed himself in the details, created a compelling argument, and performed like a howitzer tank during the trial by shelling the oppos...ition at every turn. This is the guy you want representing and fighting for you. Bryan is informed about law, direct, and realistic. I appreciate his willingness to do a little extra at times as well. Hire Bryan if you're in need of high-end representation.

Great Lawyer!

I’ve been working with Bryan on post divorce decree matters since 2017, but I wish he had been my attorney all along. I hired 5 attorneys before him and Bryan has proven to be very knowledgeable, honest, reliable, well-prepared and thorough. His advice is solid, and he is always 100% professional no... matter how unprofessional the other side might be. We have been working to clarify unclear language in my decree and when he writes up the orders, he makes sure to not leave room for interpretation. His attention to detail and legal know-how has certainly helped win my cases. It’s a relief to finally have an attorney who cares and fights for you!
