Attorney Roman Kostenko posing outside

In 1999, I received my green card after immigrating to the U.S. from Russia. Beyond granting me the rights to be a permanent U.S. resident, the green card application process also inspired me to become an attorney. You see, my own immigration attorney dropped the ball, and I ended up completing most of the application on my own. After familiarizing myself with U.S. immigration law and successfully receiving my green card, I figured I could help other immigrants with the process, too. So, the same year I became a permanent legal U.S. resident, I also took the LSAT and enrolled in law school. 

As my education progressed, I began to cultivate an interest in many areas of the law, and I decided it was best not to limit myself to any one subset. I have continually found that my broad background allows me to better see the big picture and more effectively resolve individual cases. For example, if a person who owns a business comes to me seeking a divorce, my knowledge of business law would allow me to help restructure his or her company or complete a buyout of the other spouse’s interest, and my real estate training would assist me in negotiating the terms of their current lease agreement, or a new agreement if they decide to relocate the business.

Due to my own past, I have a unique understanding of the lasting impacts of a single case or circumstance. After all, if I’d never have obtained my green card, I wouldn’t have had the opportunity to build my career as an attorney in the U.S. or enjoy the life I do today. For this reason, I’m just as emotionally invested in my clients’ cases as I was in my own. I do whatever it takes to attain a positive result. 

I work in a service profession, and my ultimate goal is to provide you with peace of mind.


Perhaps the biggest way I can provide quality representation to my clients is by furthering my education. While the State Bar of Arizona only requires 15 hours of continuing legal education courses (CLEs) every year, I often far exceed this number, sometimes reaching over 200 hours in a 12-month period. As a member of the National Business Institute, I have access to unlimited live and online seminars, and it would simply seem wasteful to not take advantage of the invaluable resources within my reach. Due to the high number of CLEs I take every year, I am also proud to be a member of the Texas Bar College, which is an honor given to attorneys who take 45 or more hours of CLEs every year. 


Outside of the firm, I spend most of my time with my family. I have two boys, ages 10 and 13, and we enjoy traveling and spending time outdoors. Whether we’re at the lake, the beach, or the mountains, I try my best to keep our trips adventurous because, much like in my practice, I believe it is important to continually learn and explore.
