Andrew D. Oostdyk 

Senior Associate Attorney

"With 18+ years of experience as a Family Law Attorney in the DFW area, I am confident in my ability to excel in the representation of my clients.

My experience includes the full range of family law matters, from the initial consultation, client onboarding, drafting of pleadings, preparation for temporary orders hearings, mediations, discovery, final trial and drafting and entering of Orders.

I value my relationships with my clients as well as my fellow attorneys, Judges and other professionals in our legal community.

I strive to settle cases amicably and in the client’s best interests, but I am always ready and willing to have a contested hearing when needed."
