McDonald Carano Expands Employment and Government Affairs Practices

November 4, 2019 – McDonald Carano is pleased to announce the addition of two highly accomplished attorneys, highlighting the firm’s continued commitment to expansion in Nevada. Mackenzie Warren joins the firm in Las Vegas as a Vice President in the Government Affairs & Advocacy Group, and Diane Welch joins the firm as an attorney in the Employment & Labor Group.

“Because of the unique background and perspective that both Mackenzie and Diane bring, they will be great assets to the firm and our clients,” said Jeff Silvestri, managing partner of McDonald Carano. “We welcome them both and look forward to working with them as part of the McDonald Carano team.”

Mackenzie Warren is a Vice President in the firm’s Government Affairs & Advocacy Group where she focuses on practical legislative solutions for clients in Southern Nevada. She began her career as a two-time Emmy nominated television news anchor and reporter for the NBC affiliate in Las Vegas and Reno, where she covered all of Nevada, including Clark County and several municipalities during the Great Recession and recovery. She served as the station’s investigative reporter and Capitol Correspondent covering the Nevada Legislature in both the 2011 and 2013 legislative sessions.

Ms. Warren began her legal career focusing on litigation before moving into her Government Affairs practice. She has litigated before the Nevada Supreme Court, the United States District Court for the District of Nevada and the Eighth Judicial District Court, Clark County Nevada – Civil and Family Division. She also handles land use issues, including property development up and down the Las Vegas Strip and beyond. She received her J.D. from the William S. Boyd School of Law at UNLV.

Diane Welch is an attorney in the firm’s Employment & Labor Group, where she will focus on a wide array of employment matters, including Title VII claims, ADA discrimination claims and contract claims. She has extensive experience arguing before both state and federal courts and defending against Constitutional law claims. She has also handled investigations into EEOC and NERC charges and works to ensure employee policies are in compliance with federal and state laws.

Ms. Welch also has a significant background in higher education law. Prior to joining McDonald Carano, she was an Assistant General Counsel at the College of Southern Nevada (CSN), where she served as the lead attorney for all aspects of litigation. In this role, she achieved an impressive 95% dismissal rate, with the remaining 5% resolved on terms that were favorable to the college. Ms. Welch was also a member of the negotiating team for CSN’s first collective bargaining agreement with academic faculty. She earned her J.D. from the William S. Boyd School of Law at UNLV.
