Marian C. LaLonde

Partner, Quarles & Brady LLP

2018 Medal of Merit Under 40 Recipient

Marian LaLonde vividly remembers breathing a sigh of relief when she discovered a local nonprofit dedicated to helping homeless youth -- Youth on Their Own ("YOTO"). She was a high school junior living on her own and working two jobs. She wasn't just thankful for YOTO's financial assistance and free toiletries, but for the emotional support as well. YOTO's encouragement was a turning point in a life previously marked by violence and juvenile delinquency.  LaLonde turned her focus towards horses and an agricultural education program that she credits with saving her life. She was selected as Arizona's outstanding vocational student and was honored as one of Tucson's Ten Outstanding Teen Citizens. Lalonde was intent upon continuing her education at the University of Arizona and pursuing a degree in agriculture, which she accomplished in 2001. She then went on to earn her Juris Doctorate at the University of Arizona, James E. Rogers College of Law in 2006.

Lalonde worked as a Rule Writer for the Pima County Department of Environmental Quality and, after earning her law degree, she was hired as an Associate Attorney at DeConcini McDonald Yetwin & Lacy PC. There she became a shareholder and honed her skills in mining law under the tutelage of John Lacy. She was honored in 2008 as the 40 Under 40 Woman of the Year by Tucson Business Edge and has been named on Southwest Super Lawyers® magazine Rising Stars list from 2014 – 2017.

In 2013, Ms. LaLonde joined the Tucson office of Quarles & Brady LLP as a Partner in the Energy, Environment & Natural Resources Practice Group. Her practice now focuses on real estate, public and tribal lands, natural resources, mining, environmental, energy, corporations, tax-exempt organizations, and equine law.

Ms. LaLonde served on the Board of the MFSW from 2013 – 2014 and led the Strategic Planning Effort of the MFSW in 2014.  Additionally, LaLonde has served and currently serves on the Board for several nonprofit organizations including the Community Foundation for Southern Arizona and YOTO. LaLonde also continues to advocate for at-risk youth by speaking at events and seminars about her experiences in foster care and as a homeless teenager.

In her spare time, Ms. LaLonde competes in the eventing and show jumping disciplines with her horses Scarlett, Brooklin, and Owen. Ms. LaLonde also enjoys life on a ten-acre mini ranch with her husband Greg, six dogs, and one cat.
