Excellent Team and Trans-Friendly!

I highly recommend Katherine Siegfried’s office for representation of any disability or SSI case. I reached out to Katherine’s office after my SSI case was initially rejected and I had to begin the appeal process. I was unable to work, I was losing my housing, and I found the process to be overwhelmi...ng and hostile, even with my own background in professional advocacy. When I called Katherine’s office, I was connected with Mika, one of the legal advocates, who went over the details of my case with me in a free consultation. She was very understanding of how taking care of myself had become a full-time job for me, and that my younger age should not disqualify me from being too disabled to work. It took about two years total to get approved for SSI, and someone from Katherine’s office was with me every step of the way since I signed up for their assistance. One of their other legal advocates, Jacob, has been my primary point of contact and is especially attentive, knowledgeable, and kind. I don’t think I’ve ever had to wait more than 2 business days for an email reply, and I could reach Jacob by phone immediately (although email communication is easier for me). At one point during the process, I was feeling very sick and I had difficulty checking and responding to emails and mail for months. Jacob made multiple attempts to reach out to me, and thankfully the office continued to work with me and was very understanding about why I was struggling to respond. Furthermore, I let everyone I worked with at the office know that I was transgender (non-binary) and used they/them/theirs pronouns. Everyone was always very respectful of that, and they tried to give me as much agency as possible within the binary system that the Social Security Administration enforces. Everyone at the office introduces their pronouns in their email signatures and the office feels very trans-friendly. Although I was originally working with a different lawyer, Ambreshia, for my case, Katherine unexpectedly needed to represent me at my court hearing close to the hearing date. She made sure to fully review my case and met with me twice before my hearing to go over the process, the details of my case, and any questions I had, and then once more right after the hearing to check in and see how I was doing. She did an amazing job and I felt fully understood and represented. They helped win my case even when Social Security Administration’s contracted doctor tried to claim I wasn’t disabled enough. They took care of hours of calling, thousands of pages of medical documentation, and staying on top of all notices and requirements from Social Security. Even after Katherine’s office received payment, they have continued to give me advice and are helping me resolve an issue. I feel that Katherine’s team truly cares about their clients beyond just a form of payment. Working with Katherine’s team was completely worth the cost from my backpay, and I would recommend anyone eligible to work with her office. Having a lawyer during this process helps a lot, and Katherine’s office has demonstrated dedication, experience, competence, and care.

Excellent Attorney!

Katherine and her team are professional, thorough and knowledgeable. We had been trying to get my disabled son SSI for 3 years, and when it went to hearing decided we needed help. Katherine won his case without us even having to go to hearing! They knew exactly what to do and how to do it every st...ep of the way. She and Jacob were easy to communicate with and quick to respond, and it felt like they genuinely just wanted to help. They have been caring and responsive all the way to the end, even when we realized their payout would not be as much as expected. We are so grateful to have had their support, without it I'm sure we would still be struggling. Thank you Katherine and Jacob!

She won my case; amazing team

Katherine is an exceptional attorney. Her staff is just as focused, driven and personable as she. (Jacob especially) Calls are returned, sessions are scheduled, and she is superb in crafting briefings to the judge which lays the groundwork for the disability claim. I came to her after I was with anot...her attorney for two years, who finally looked at my file six weeks before my scheduled court date and withdrew. I was under fifty and she felt she couldn’t win my case. It was an ethical breach, and no other attorneys would take my case as they had to start researching/writing a brief immediately even with a rescheduled court date. Not only did Katherine take my case, but with a full client roster, over three thousand pages of medical records, won my case before an administration law judge with a scant three months as my attorney. She and her team are simply amazing. They are kind, welcoming, and lovely people. Winning my disability case helped me and my family so much. I thank my stars I found her and you will too.

Professional, Helpful, and Caring

Mika, Jacob and the rest of the team took our case seriously, handled each step of the process with compassion and professionalism. We never felt like we were “just another case,” and were impressed with the care that the office took to prepare the case and us for our hearing. Definitely a positive e...xperience and a successful outcome.

Best practice

There is not enough room here to share all my gratitude for the amazing legal team at this attorney's practice. They are LGBTQA+ friendly (correct pronouns!). They are respectful and communicative with developmentally disabled adults (of which I am one). They are an intelligent, methodical team and f...ight for you, not just for their paycheck. They helped me win my 2+ year-long disability appeal process and stuck with me through the entire run(after I hired them). They never gave up and were kind all the way through. This is a legal team with integrity that definitely deserves their percentage cut at the end of it all. I doubt I would've been able to navigate the SSA labyrinth on my own. They are an invaluable resource and 'one of the good ones'. If you're looking for representation, look for further. Please reach out to them today. If they CAN help you, they will: absolutely. They won't just look for an excuse to pass on your case. The consult is free and they receive no payment unless you get approved for benefits. I really cannot say enough nice things about them. Staff, if you're reading this, you're the best!! Stay awesome. I'll always be grateful for everything all of you did for me and my case.
