By: The Partners of Lanton, Lanton & Sosa
We are thrilled to share some major news with our clients, colleagues, and friends.
If you’ve visited our website today or seen our recent press release, you likely noticed a change. Lanton Law, PLLC has officially rebranded to Lanton, Lanton & Sosa Law, PLLC.
This isn’t just a name change—it’s a reflection of how we are evolving to meet your needs. Over the past few years, our clients have asked for more support in complex areas like real estate, technology, and corporate growth. We listened, and today we are expanding our team and our practice to deliver exactly that.
Meet Our New Managing Partner
The "Sosa" in our new name belongs to Maria Sosa, whom we are honored to welcome as our new Managing Partner.
Maria is not just joining the leadership team; she is bringing an entirely new capability to the firm: Commercial Real Estate. Whether you are navigating property development or complex transactions, Maria’s expertise adds a critical pillar to the services we offer. She will also be heavily involved with our healthcare and technology clients, as well as with Lanton Strategies International. There she will be driving advocacy for our clients across the Northeast.
Expanded Services for a Changing World
Alongside this rebrand, our existing leadership is taking on new strategic roles to broaden our scope:
Ron Lanton is now Senior Partner and Global Strategist. While he remains the dedicated General Counsel for our healthcare and life sciences clients, he is formally expanding his practice to include Mergers and Acquisitions (M&A). If your company is looking to grow, acquire, or exit, Ron is ready to guide that strategy.
Casandra Lanton has been appointed Chief Legal Officer. She is expanding her expertise beyond Human Resources and Employment Law to include Technology Law, ensuring your business is protected in an increasingly digital and regulated environment.
Bridging D.C. and New England
We know that policy decisions made in Washington often have ripple effects on business operations in the Northeast. That is why we are solidifying our footprint.
Headquarters: We remain rooted in Washington, D.C., at the center of legislative and regulatory affairs.
Principal Operations: We have established a major operational hub in Boston, Massachusetts, allowing us to serve our New England clients more directly.
What This Means for You
If you are a current client, the only thing changing is our letterhead. You will continue to receive the same personalized, high-level counsel you rely on—now with even more resources at your disposal.
Thank you for trusting us with your business. We are excited to step into this future with you.
