About Marcus
Biography
I am passionate about helping people formulate plans to reach their goals. Since 1999, I have been involved in that process with hundreds of clients as a professional in the financial services industry. In 2011, I enrolled at Arizona Summit Law School. It wasn’t always easy balancing family and school while maintaining a growing financial services company. But with the help of my wife and others, along with some divine intervention, I graduated with honors (summa cum laude) in 2014. The rest is history. Now I spend my time helping individuals and families create and maintain solid estate plans – truly an important work!
On a more personal note:
Before becoming an attorney, I grew up in Scottsdale, went to Horizon High School, and then joined the United States Marine Corps Reserves. Following my active duty training, I went on a 2 year mission for the Church of Jesus Christ of Latter-day Saints and later graduated from Arizona State University – go Sun Devils! Along the way I moved to Mesa where I met my sweetheart – Jennifer. We were married in 1999 and have since been blessed with 6 children (4 boys & 2 girls)! So when I’m not at work, I’m usually playing with my family, fixing up the house, or playing basketball.

Marcus Seiter did an outstanding job handling our will and trust. I found his knowledge and advice to be extremely helpful. I would have been lost had I tried to do this process myself. I will be returning to him the next time I need an attorney.
