    I endorse this lawyer's work. I have been opposing counsel on several matters with Mr. Valen. I have also referred several cases to his office. In my experience, Mr. Valen treats clients, opposing counsel and opposing parties with respect and dignity. He works with counsel to seek meaningful and appropriate resolutions, while at the same time staunchly protecting his client's interests. It is a pleasure to work with a family law attorney of his caliber and integrity.

    Mr. Valen is one of the most professional attorneys I know. He possesses excellent analytic, trial and negotiating skills. Additionally, he is adept at helping his clients through the emotional roller-coaster that is family law litigation. In multiple cases, I have seen him assess the strengths and weaknesses of a case, then use that information to skillfully move the case forward. I have tremendus respect for Mr. Valen as an advocate, trial attorney and collegue.
