Hired Attorney Chase Tajima

Facing Bankruptcy, wrongfully terminated by a state agency after 28 years based on false claims which then evolved into a civil suit against me! I felt hopeless—My former attorney ruthlessly abandoned me and no one else would touch my bleak situation until I found Chase! He responded immediately, acted quickly with compassion and a commitment to justice. Chase and his team overturned an appeal dismissal and provided me with WINS resulting in indemnification, closure to the civil lawsuit & recovery of attorney fees from the state. Chase, Ms. Dale and the whole team have been attentive throughout this stressful time, answering questions without hesitation at all hours and even on weekends. Their dedication to fighting for the truth and their ability to take on challenges others were intimated by is truly remarkable. If you are looking for a law firm that genuinely cares, with integrity and delivers results, I recommend Chase Tajima and his team. He turned my despair into confidence.

I went to Chase for a consultation regarding issues with my previous Real Estate agent. He offered me great advice on how to approach the situation professionally. Thankfully, his advice allowed us to move forward without legal processing. Thank you, Chase!

Hired Attorney Chase Tajima

I wholeheartedly recommend Chase and his firm. What truly stood out to me was the attentiveness and warmth of his entire team, they were not only professional but genuinely kind and supportive throughout the process. My case was built on a web of complete false claims, and navigating it was emotionally overwhelming. Chase was more than just my legal representative; he provided unwavering emotional support and guided me through every step with a reassuring, hands-on approach. In what was an incredibly daunting time, he made me feel safe, informed, and empowered. What impressed me most was his integrity. Rather than prolonging the case for the sake of billable hours, he proposed a bold and strategic approach designed with my long-term well-being in mind. His plan was both aggressive and innovative, ultimately leading to the dismissal of the case. Chase is truly exceptional, like a ninja in the courtroom: one swift, precise move, and the opposition didn’t stand a chance.
