My name is David Gerszewski and I am an Estate Planning Attorney and Tax Lawyer. I was born and raised in North Dakota and first moved to Arizona in 1992 to pursue graduate studies in applied statistics at Arizona State University. My first career working for Wall Street investment banks and hedge funds took me to New York and then to London for almost 20 years. After leaving institutional finance, I moved to Florianópolis in South America where I developed a restaurant franchise concept that spread throughout southern Brazil.

I again made Arizona my home in 2014 and now operate the Citadel Law Firm ® based in Chandler serving east valley clients in estate planning, wills and trusts, and tax law. Our law practice designs personalized estate, business, retirement, and tax planning strategies for clients, which are designed to coordinate with clients’ existing investments, pensions, life insurance, and annuities. Through a legally distinct financial planning entity that is not a law firm, our clients may also receive guidance on investment management and life insurance retirement planning (“IMLIRP”) strategies.

I draw on extensive commercial and international experience to represent clients developing new businesses, protecting intellectual property (trademarks, copyrights, and patents), planning for business succession, and resolving related legal issues as they arise.

We approach our clients like family. My unique background across several industries in investment banking, investment management, small business entrepreneurship, tax, and law allows me to provide comprehensive, coordinated, and optimized solutions tailored to clients, their families, and their businesses. This coordinated approach for most clients results in financial security, peace of mind, and a clear understanding of the resources that will be available when difficult times arise.

Please contact me to arrange an appointment to discuss your matter.

Legal Answers
9 Questions Answered
Q. My husband changed his trust one month after his brain tumor diagnosis and died less than 2 months later. Legal?
A: Assuming your husband was still of sound mind and the attorney followed all the Arizona state law requirements, it should be legal. You can contact an estate litigator and see if there is room to go to court to contest it.
Q. My father passed away in December 2022. He had a Will and a Trust listing his 3 adult children as recipients of all
A: The lawyer's position is right. The lawyer represents the trustee. You can hire your own lawyer to discuss matters with the trust lawyer if you want. Your cousin should still follow guidelines for administering the trust according to Arizona law.
Q. Completed a will from a kit and had it notarized. No witnesses. Will this be valid when I die?
A: In Arizona the Last Will and Testament will be valid, but it will not be self-proven.
