About Marcus N Seiter

Estate Planning, Wills, Trusts, Powers of Attorney, and Peace of Mind - Contact Seiter Law for a free consultation!

About me: 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.

I look forward to meeting you! – Sincerely, Marcus Seiter

Seiter Law We have been a client of Seiter Law for many years and never disappointed. We recently purchased a new home and needed to transfer the Title into our Trust. Marcus and team made the process completely transparent. All we did was show up to the appointment, sign, and new Title was mailed to our home. We love working with Seiter Law and highly recommend them to others.

We would highly recommend Steiner Law for anyone needing help with setting up a trust. Marcus is incredibly thorough and transparent about costs and what to expect throughout the process. We especially appreciated the convenience of having everything handled right in his office—simple, efficient, and stress-free. Start with a consultation—you won’t be disappointed!

My husband and I had the pleasure of meeting Marcus Seiter at Seiter Law. He was very pleasant and updated our trust. We had a lot of questions, and he was able to give us clear answers that we understood. He sent us a planning document before our appointment which helped a lot in getting our documents together for the appointment. We highly recommend Marcus for his services.

I had my first estate planning meeting with Marcus two weeks after my husband's passing. I knew it was time to have a will - trust in place. Marcus was compassionate and slowly explained the first steps with me. All his work was completed professionally and he spent a lot of time ensuring I understand each document throughout the entire process. The living Trust will prevent our daughters from the pain of probate when I pass. I have a sense of peace knowing all the properties are in order and will be a smooth transition. I highly recommend Marcus for estate planning. His expertise is worth every dollar spent.

I had an exceptional experience working with Seiter Law during my family’s estate planning process, which included the creation of a revocable trust and will. Marcus Seiter demonstrated a notable depth of expertise, coupled with a poised and highly professional demeanor. I especially admired his quick wit and ability to inject well-timed levity into an otherwise somber review of post-mortem topics regarding oneself. He took great care to address both straightforward inquiries and more nuanced legal questions with clarity and patience. Equally commendable was the consistent transparency and responsiveness of his team—particularly Jennifer Seiter—whose communication throughout the process was both timely and reassuring. I am thoroughly satisfied with the services provided by Seiter Law and, without hesitation, offer my highest recommendation to anyone seeking thoughtful, thorough, and expert guidance in estate planning.
