The Advocate You Need by Your Side, Championing Your Cause! I wanted to share my experience working with Kathleen Tannian because it truly made a world of difference in my life! When I found myself in a deeply challenging situation with my former wife, who was struggling with mental health issues and aiming to gain full custody of our child, I knew I needed the right legal support. Kathleen Tannian was my guiding light during this legal battle. Her unwavering dedication and legal tenacity were evident from the moment we began working together. She fearlessly advocated for me with an impressive level of assertiveness and professionalism, making sure my voice was heard in the legal proceedings. I was amazed by Kathleen's deep understanding of the intricate nuances within family law. Despite some perceiving her approach as aggressive, I found it to be a key attribute that set her apart, fostering trust and confidence in her clients, including myself. It was clear to me that she wasn't just representing me; she was fighting passionately to safeguard my rights and the well-being of my 8-year-old son, whom I cherish deeply. Kathleen's exceptional memory and thorough approach to every detail of my case left me feeling reassured and supported. She never missed a beat, and her honesty and transparency were incredibly comforting during what was an emotionally challenging trial. Kathleen's assertiveness and unwavering dedication were instrumental in securing shared legal custody for my son. It was a victory that seemed impossible before she stepped in with her expertise and unwavering commitment. My experience with Kathleen Tannian went far beyond legal representation. She was not just my lawyer; she was a committed advocate who stood by my side every step of the way. Her proactive approach ensured that I was always well-prepared and informed, easing the stress of the legal battle. I wholeheartedly recommend Kathleen and her firm to anyone in need of legal expertise, as she truly is the ally you want on your side during any legal dispute. With Kathleen Tannian, you can be confident that your rights and the well-being of your loved ones are in the most capable and compassionate hands. I praise the Lord for leading Kathleen Tannian to cross my path! - A. Carlos

In The Highest Regard I would absolutely recommend Attorney Kathleen Tannian. Her practice specializes in different areas of law. I have myself used her services for two unrelated legal matters, one being a Guardianship, the other for a Domestic mater related to Divorce. Kathleen is professional, compassionate and most importantly, "she knows the law." Her dedication to her clients is endless and her determination to obtain the best outcome for her clients never waivers. Simply, I couldn't have hired a better attorney.
