Excellent Attorney!

I cannot recommend Mark highly enough! He represented me in dependency court and achieved what seemed like an uphill battle: securing 50/50 custody for me. From start to finish, Mark demonstrated not only his incredible intelligence and deep knowledge of the law but also his eloquence and confidence ...in the courtroom. Mark’s communication skills are top-notch. Whether by email or text, he was always prompt in responding to my questions and concerns, keeping me informed every step of the way. His honesty and reasonableness gave me complete confidence that I was in excellent hands. What sets Mark apart is his experience and ability to anticipate and prepare for every possible hurdle. He was always one step ahead, ensuring that my case was presented as effectively as possible. His preparation, combined with his calm and commanding courtroom presence, made all the difference. If you’re looking for an attorney who is knowledgeable, communicative, and truly dedicated to your case, Mark is the one you want by your side. I’m so grateful for his representation and the life-changing results he achieved for me and my son!

10/10! Would recommend

Dedicated, meticulous, confident, steadfast, knowledgeable and unshakable are all words that can be used to describe Attorney Mark Tseselsky. The manner in which he handled everything, including my nervous bouts, is what made all the difference. His professionalism and vast knowledge insured the safe...ty of my child as well as mine. I am so grateful I was referred to him.

A blessed ending!

I was referred to Mr. Attorney Mark Tseselsky in an urgent situation. Not only did he help me gain custody and visitation of my children while fighting a violent criminal case but also helped get rid of a social worker attempting to investigate my case and helping me finalize my divorce. I have no wo...rds that can explain the gratitude I have towards Mr.Tseselsky and his assistant Mrs.Lilit Tevosyan. I’ve learned a lot from him these past 21 months especially patience and respect. He knew how to keep calm when opposing party was brutally disrespectful and arrogant with minimal interest towards my 4 children. He fought hard, many times late hours preparing for my case spending late evenings in the office getting me visitation time with my children when he could’ve been home enjoying his own. Bitter sweet moment for my case to finally end. As I hope and pray to never need an attorney again, I will most definitely keep him saved and in mind at all times. Thank you for everything and I apologize once again for all the disrespect you went through with opposing party. - Family Topete

Mark L Tseselsky

I can’t express how much I appreciate Mark. My life has been in total chaos lately. I have been in constant ridicule, judgment and have been treated unfairly in the eyes of the court. It was Mark who has wipe my tears and gave me my strength when I needed it most. Mark is the Epitome of hard work, Di...ligence, professionalism and strength. Mark was my voice when I felt I did not have a voice or couldn’t have a voice. Mark stood up for my character, my kids, my career and my life. I have never met anyone who was willing to fight for me when all odds even when those odds were incorrect and false as hard as Mark did. I expressed to Mark what I had to lose in my case and how passionate I am about my career and my children and I’m so honored to have met a man who gave everything in him to fight for my cause. Because of Mark I got the best outcome out of my case. Mark thank you for all of your hard work, thank you for giving me my voice back, thank you for believing in me when I did not believe in myself, thank you for being the BEAST you were in court and thank you for the impact you had on my life. I don’t think I could ever repay you or pay you enough for what you have done. It was definitely a pleasure to have done business with you!

Mark Tseselsky is an excellent Juvenile Dependency Attorney

I would highly recommend Attorney Mark Tseselsky to anyone with a case in dependency court. I had a very complicated case and the lawyer I was initially considering to hire was too busy to dedicate the time and effort needed to learn the critical background information needed for my representation. B...y a stroke of luck I found Mark who was 110% on top of every detail of my case from start to finish. He gave excellent advice and maintained communication with me and the other parties involved to get ahead of the game every step of the way. In the end, I got my kids back and my case was closed months before anyone would have ever anticipated. Dependency Court is stressful, scary, and unique in its procedures. Mark knows this system's inner workings and is expertly capable of tackling the various phases of case progression. I would never wish for anyone to go through the trauma of having a case in Dependency Court. But if you find yourself there, my experience with Mark Tseselsky allows me to confidently say that he can give you stellar representation, honest billing, and priceless advice to help get you through.

Relationship: Worked together on matter

"I worked with Mark as co-counsel on a very difficult and complex real estate litigation. We spent over 2 years defending the case for the brokerage firm and its agents. Mark was instrumental in filing a Motion to Disqualify Plaintiff's counsel which caused Plaintiff's to hire another less experienced attorney. He then successfully changed the venue from LA County to Riverside County. He showed tenacity and respect before the judge, winning every single motion against Plaintiff's new counsel. Eventually, his strategy and aggressive posture forced Plaintiff to compromise in a court ordered mediation. I look forward to working with Mark again on future cases. You can be assured that he's got your back."
