Many homeowners in our townhome community have used Sumner Law, and we refer our neighbors and fellow homeowners to them whenever legal representation is needed. What truly sets Drew and Sonya apart is the genuine care they have for the people they serve. Over the years, they have become more than just attorneys to us they have become like family. If you are looking for attorneys who are knowledgeable, trustworthy, dedicated, and truly invested in their clients, Sumner Law is the firm to choose.

I cannot recommend Sumner Law highly enough. They have provided exceptional legal guidance for both my business and my family's personal planning, and their professionalism, knowledge, and attention to detail have been invaluable every step of the way. They are incredibly responsive, thorough, and genuinely care about their clients. Whether navigating business matters or helping us plan for our family's future, they always take the time to explain everything clearly and make what could be stressful situations feel manageable. Having someone I can trust with both my business and personal legal needs has been priceless. If you're looking for legal professionals who are knowledgeable, compassionate, and truly go above and beyond, I highly recommend them.

I've been a small business owner for many years, running a hair salon, and Sonya and her firm have been my trusted advisors throughout that journey. Their guidance has always been prompt, on point, and exactly what I needed – whether it was reviewing my previous salon's sales agreement or a new business lease review. What truly sets them apart is the way they work with small business owners. Their service is personable, professional, and far more reasonable than many peers in the industry. I always feel like they genuinely care about me and my business's growth, not just the transaction at hand. If you're a small business owner looking for legal support you can rely on, I highly recommend Sonya and her team. They've been invaluable to me over the years, and I'm grateful for their expertise and their heart.

I am having some major construction work done on my house. The contractor prepared the contract for the job that had so many clauses that were difficult for me to understand. I retained Sumner Law to review the contract before I signed it. Sumner Law did a fantastic work reviewing the contract. They made a number of changes to the contract that would have otherwise cost me lots of money if they were not changed/amended. Both lawyers, Sonya and Drew, are professional, knowledgeable and very courteous. Their fees was amazingly low for the work they performed and they were always available to answer any question I had. I strongly recommend this law firm to anyone who needs any kind of legal assistance.
