Best switch I ever made, Great Attorney that Produced Results

avvo-badgeI hired Mr. Zimmer about a year ago to handle my divorce case. I met with Mr. Zimmer after going through a case for two years with another attorney. At the time of my first initial consultation with Mr. Zimmer, I was immediately impressed with his knowledge on divorce matters. My previous attorney had never mentioned half the things Mr. Zimmer did that we could do for my case. I came in there with next to no money, barely being able to keep my head above water and finished a few months later feeling completely satisfied with the results. Mr. Zimmer put more effort into my case in a few months than my prior attorney did in two years!

Dependable, professional and reliable are a few words that describe the work of this attorney. I am grateful for his time and how he handled my situation with care to the minors involved. I would highly recommend this attorney to my friends and family and will defiantly use him again, if needed.

Positive Experience Throughout a Frustrating Alimony Situation

avvo-badgeAfter going through mediation with my ex-wife, about two years into a four year required period of spousal maintenance circumstances with my ex-wife changed with led me to believe that my spousal maintenance requirement should be terminated. I met with Todd and explained the situation and being very knowledgeable in the case law he immediately let me know that I had grounds, but additionally performed a thorough research project to find similar cases and be sure that we had a good argument, which as it turned out we did…
