    "We are so grateful to the team at Brewster & DeAngelis."
    When we came to Brewster & DeAngelis, we had no idea what we wanted or what we were doing. We were broken and grieving and trying to make sense of a senseless situation, and Guy, Monty, Clark… the entire office, really, starting with the front desk… stepped in and took the burden off our shoulders. We didn’t have to worry about what we were doing or what we wanted anymore because they took the lead in a compassionate and efficient manner- they truly cared about helping our family and they didn’t ask us to carry any additional burdens- they took time to discover what we didn’t know we needed and they took care of business. They also made sure to address all of our needs outside of a “typical” legal experience by encouraging and facilitating our advocacy and educational awareness. We never wanted to need an attorney, but when we did, we were blessed to find amazing friends and supporters. We are so grateful to the team at Brewster & DeAngelis.

    From the moment I reached out to them, their commitment to ethical standards and unwavering support shone through. Their dedication to doing what's right not only instilled confidence in their legal expertise but also made me feel genuinely cared for. Throughout my case, their kindness and support made a significant difference, making a challenging situation feel more manageable. I couldn't recommend Brewster & De Angelis Law Offices highly enough for their exceptional ethics and compassionate approach.

    "There are no words for how grateful I am to the entire Brewster & De Angelis team and how hard they worked to get justice for my son, Gavin, after 4 long years."
    There are no words for how grateful I am to the entire Brewster & De Angelis team and how hard they worked to get justice for my son, Gavin, after 4 long years. I sat in the court room for seven days and saw how hard each and everyone worked and the fight they put in each time they got up. I saw how much they cared. I strongly believe if it was not for this team, I would not have gotten justice for Gavin in his medical negligence case. I will forever be thankful.

    "I will forever be grateful to the zealous lawyering and selfless generosity of this extraordinary law firm."
    My family and I are so grateful for the countless hours and all the hard work that each attorney and staff member of Brewster & De Angelis devoted over several years in the pursuit of justice. Clark Brewster and Katie Arnold McDaniel took the time to discover what no other person - not my previous defense attorney, the district attorney, or the Court - took the time to find. The erroneous cancelation of my driver’s license was the product of a court clerk’s mistake. What an amazing team! I will forever be grateful to the zealous lawyering and selfless generosity of this extraordinary law firm.

    "Five stars!"
    Five stars! Katie is one amazingly smart cookie! Once she enters the room, you know you're in good hands! Also, probably best not to get on her bad side, you'll lose!

    "I cannot recommend better advocates than the Brewster & DeAngelis Team."
    The office staff is polite, competent, and caring. Mr. Brewster and Mr. Fortney were generous with their time, giving detailed and informative advice. Katie Arnold McDaniel is a star. She has counseled me through various case types. Her ability to quickly understand information relevant to a dispute, analyze the issues, and find the means to resolve them is amazing to watch. Katie is a fierce advocate, compassionate, and trustworthy. She timely communicates and will do what she says she will do. I highly recommend this law firm.

    "Mbilike is the most ethical and honest attorney around and his work ethics are top notch. Thank you Mbilike"
    Mbilike with Brewster & De Angelis represented me as a defendant in a case in Claremore Oklahoma. we went through 2.5 years of discovery, depositions and on into trial. His work was excellent and stood up to everything that the opposing council threw at us. The judge was obviously impressed by his writings and responses as well. We won on every account, and did not even argue our case after the plaintiff rested, as we knew the judge had all the information needed from the plaintiffs argument. this was a long arduous suit by some really unethical people and Mbilike put it on without a hitch and received a big win. Mbilike is the most ethical and honest attorney around and his work ethics are top notch. Thank you Mbilike
    - Jim C.
    "We will be forever grateful to them for giving us a chance to live again, following the single worst day of our lives."
    Jennifer and her team have been invaluable in helping us navigate life following my father's injury. The negligence of medical "professionals" left our family broken and afraid. Without the assistance of this wonderful team, we would not have ever recovered. They advised us, listened to us, supported us, and fought for us when no one else would. We will be forever grateful to them for giving us a chance to live again, following the single worst day of our lives.
