Truly the best family attorney!

Without all his help and incredible legal advice, I would undoubtedly have been in a much more precarious situation. He worked tirelessly to ensure the best possible outcome on my behalf. I cannot thank him enough for all of the hard work and effort he put into my case. I would not hesitate to re...commend Mark Tseselsky to anyone in need of an experienced family attorney!

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!

Recommendation for Mr. Mark as an Exceptional Family Lawyer

Recommendation for Mr. Mark as an Exceptional Family Lawyer I am writing to express my utmost satisfaction and gratitude for the exceptional legal services provided by Mr. Mark in handling my recent divorce case. It was truly a pleasure to do business with Mr. Mark, and I am delighted that he r...epresented me throughout the entire process. His depth of knowledge and expertise in family law were evident from the outset, and he consistently provided me with invaluable legal advice that guided me through this challenging time. One of the things that stood out to me about Mr. Mark's approach was his ability to cut through the complexities of the case and get straight to the heart of the matter. He was always honest and transparent, never hesitating to tell me whether it was worth fighting for certain aspects or not. Furthermore, I was impressed by the clarity and transparency of Mr. Mark's billing statements. Each statement provided a detailed breakdown of the services rendered, making it easy for me to understand and track the costs involved. Based on my personal experience, I wholeheartedly recommend Mr. Mark as a family lawyer to anyone in need of expert legal representation in a divorce case. I have no doubt that his professionalism, integrity, and dedication to his clients will ensure the best possible outcome for anyone facing similar circumstances. Once again, I would like to extend my sincere thanks to Mr. Mark for his outstanding service and support throughout this process.

Real estate lawyer | Nov 04

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."
