Irwin and Irwin Family Law Attorneys
I contacted Kelly and Mark Irwin, after going to court alone without representation, regarding an assault case and abandoned mediation. Both Kelly and Mark are very familiar with Family Law and how it works. I felt secure that they would do a very good job for me and they did. I was most impressed with their professional and knowledgeable approach on how to negotiate a successful end to a very disturbing case.

Couldn't be happier
I couldn't be happier with the way Mark handled my divorce. He kept me informed the entire way and I always felt Mark was working in my best interests. Mark was very understanding during the difficult times of the case and was empathetic to my situation. In the end Mark achieved everything he (we) set out to accomplish and I couldn't be happier with the results. He is truly a person of good moral character and a professional who always worked hard for his client. Thanks Mark.

I don't see how our recent case could have gone any better, or relieved me of so many details I do not enjoy. It was a wonderful experience having Mark's guidance and assistance. Mark was right on target with the decisions he left to me, and those he took by himself in our behalf, and he is clearly an enterprising person with a good ability to press his case without seeming aggressive.
