Wilenchik & Bartness

The law firm of Wilenchik & Bartness provides high-level litigation services to a select group of clients. With its many highly skilled attorneys and paralegals, the firm also provides commercial arbitration and mediation services and works closely with businesses to manage their legal needs. It has represented many high-profile individuals in the state and county, including county attorneys, judges, a senator’s son, the state treasurer, the secretary of state, and former and current attorneys general.

The firm was founded in 1991 by Dennis I. Wilenchik, who left a senior partnership at the international firm of Squire Patton Boggs to form a smaller, more personalized practice while retaining a big-firm quality of practice. Still in active practice with his son, Jack — who was selected a “super lawyer” in business litigation this year by Thomson Reuters — he was recently named Best Trial Lawyer in the Valley for the fourth straight year by Foothills Magazine, and one of the Top 100 business lawyers in Arizona by a Business Magazine. 

Dennis Wilenchik is rated Martindale-Hubbell AV®-Preeminent™, the highest rating available under the Martindale-Hubbell rating system, and he is listed in the national Bar Register of Preeminent Lawyers. Wilenchik has been a nationally certified civil trial advocate by the National Board of Trial Advocacy for more than 15 years. He is an Arizona Bar Foundation Fellow and was elected a Fellow to the American Board of Professional Liability Attorneys. Wilenchik has served as a civil judge pro tem of the Superior Court; president of Maricopa County Bar Association Young Lawyers Division; board member of the Arizona Bar Journal; chairman and secretary of the Civil Trial Practice Committee; member of the Superior Court Civil Study Committee of the State Bar; and member of the Department of Real Estate Advisory Board, appointed by the governor.
