He is a past-president of the American Legal Clinic Association, past-chair of the American Bar Association Special Commitee on the Delivery of Legal Services, a member of the ABA Consortium on Legal Services and the Public, a member of the American Association for Justice and the Arizona Association for Justice.  He is a Fellow in the Arizona Foundation for Legal Services and Education.  He was a founding director of the Arizona Center for Law in the Public Interest.

Van is av-rated (the highest rating) by the prestigious Martindale-Hubbell Law Directory.  He also was voted--by other lawyers--for inclusion in The Best Lawyers in America Consumer Guide.

Van is profiled in the publication Who's  Who in American Law.  He authored a legal advice column which appeared in various Arizona newspapers, and he is the author of numerous self-help packets which enable consumers to attend to many of their own legal needs without having to hire a lawyer.

In 1977, Van went to the U.S. Supreme Court and won the landmark case permitting lawyers, doctors and other professionals to advertise their services and fees.  As a result of this important consumer victory, the costs of legal services have declined.

Van was born in Tennessee in 1946 and moved to Arizona in 1959.
