Sophisticated Legal Counsel

Boutique Personal Attention
At Sumner Law LLP, the partners are the practice. Drew W. Sumner and Sonya M. Sumner personally handle every engagement — from initial consultation through final resolution — so you always know who is working on your matter, and why.
Our clients come to us when the stakes are high and the issues cannot be delegated: federal civil rights litigation, complex business disputes, family law, real estate transactions, and estate planning. In each, we combine the rigor of a larger firm with the accessibility and judgment of a boutique. Expect direct conversations with the attorney responsible for your outcome, plain-language guidance through each decision point, and a single partner at the table from the first call to the last.

What Our Clients Say

★★★★★
"Throughout my extremely contentious divorce, Sonya has been a pillar of support and sound legal advice. I cannot begin to express my gratitude for her direction through this very difficult period in my life. If things came up suddenly even Drew Sumner was there to be a sounding board and provide legal guidance as well. Ms. Sumner is a legal powerhouse."
Jaime
Family Law / Divorce
★★★★★
"I had an incredible experience working with Sumner Law LLP. Sonya, Drew, and their entire team were a pleasure to work with from start to finish. They helped me form my business and negotiate the commercial lease for my gym. What really stood out was how much time they took to explain everything instead of just doing the work and sending a bill."
Adi
Business Formation & Commercial Lease
★★★★★
"In a situation where my wife and I were desperate for a resolution, Sonya was able to help us get an even better outcome than we imagined when we initially reached out. While her professionalism and legal acumen were absolutely incredible, we were equally impressed with her level of care for our well-being. We truly feel she took personal ownership of our situation and fought for the outcome as if it were her own case."

How We Work With You

1

Direct Partner Consultation

Your first call connects directly with Drew or Sonya—never an intake specialist or junior associate. During your complimentary 30-minute telephone consultation, we discuss fee structures, explore how we'd approach your specific legal issue, and provide ballpark timelines aligned with your goals for resolution.

2

Partnership from Day One

Within your first 30 days, we establish a secure communication portal, review your matter thoroughly, and engage you on strategy with a clear plan of action and potential timeline. Whether you need emotional support through a divorce or practical strategy for business disputes, we adapt our approach to your specific situation and needs.

3

Proactive Partner-Level Management

Your case is handled directly by Drew or Sonya throughout—not passed off to associates. We proactively communicate deadlines, promptly forward all outside correspondence, and maintain internal systems to keep your matter moving forward. Most clients are surprised by our attentiveness and response times, with most communications answered within 24 hours.

Our Commitment: Partner Involvement Guaranteed

At Sumner Law LLP, "partner-level service" isn't marketing language—it's how we operate. Every client matter is handled directly by Drew or Sonya from initial consultation through resolution. You'll never wonder who's working on your case or struggle to reach the attorney making the decisions.
