Mark E. Andersen

Managing Partner
Scottsdale, Arizona

Mark Andersen is the managing partner of ANDERSEN PLLC. Mark established ANDERSEN PLLC in December 2013 with a vision: (1) to serve families and provide support during times of transition or death of a loved one, (2) to improve the quality of life of those who are no longer able to provide for their own needs, (3) to create order in the estate plans of individuals and to observe their intent, and (4) to promote the visions of other small business owners.

Mark earned a Bachelor of Science degree in accounting from Arizona State University in 1999. In a prior career in public accounting that began in 1999, Mark audited large and small businesses, and provided due diligence with regard to purchases of other businesses. He worked as a staff auditor for Ernst & Young in Phoenix for two years, and passed the CPA exam in November of 2000. While in law school in Chicago, Mark advised clients on commercial real estate transactions as a senior consultant for RSM McGladrey. Mark began practicing law in the area of trusts and estates in 2006. From there, he branched into other areas of law, including guardianships, conservatorships and estate litigation.

Mark graduated from the DePaul University College of Law in Chicago, IL in 2005. He was admitted to the Illinois bar later that year, and passed the Arizona bar in July of 2006. After four Chicago winters, Mark had enough and moved his family, which includes his wife (Katie) and two fun-loving kids (Gracie and Brian), back home to Arizona, where they can spend more time with both sets of grandparents. Daughters Rosie and Lottie came along in the years that followed. There are few things that mean as much to Mark as seeing families get along and honor their parents.
