Legal Counsel for Healthcare, Technology & Growing Businesses

Lanton, Lanton & Sosa Law advises companies, investors, healthcare organizations, and business owners on the legal and regulatory matters that affect their operations and growth. Our work includes commercial agreements, healthcare regulation, employment law, business transactions, real estate, and government affairs.

We work directly with executives and leadership teams who need experienced counsel for important business decisions, whether they are entering a new market, negotiating an agreement, managing a regulatory issue, or preparing for expansion.

Our Approach

Legal advice should help a business make informed decisions, manage its obligations, and protect its commercial interests. At LL&S, we take the time to understand how our clients operate, the markets in which they compete, and the business objectives behind their legal questions.

Some clients engage us for a specific transaction or regulatory matter, while others rely on the firm for continuing legal support. Our external general counsel services allow growing businesses to obtain ongoing advice without establishing a full-time internal legal department.

How We Work With Clients

Regulatory & Compliance Counsel

We advise healthcare, life sciences, technology, and other regulated businesses on legal requirements that affect their operations, commercial relationships, and market access.

Commercial Contracts & Business Transactions

We assist clients with negotiating agreements, evaluating business relationships, conducting transaction due diligence, and addressing contractual obligations associated with growth and expansion.

Employment & Workplace Counsel

We work with employers and HR leaders on hiring, compensation, employee policies, workplace investigations, termination decisions, and multistate employment requirements.

Commercial Real Estate

We advise owners, developers, investors, landlords, tenants, and operating businesses on commercial leasing, acquisitions, development projects, and property-related transactions.

Government Affairs & Regulatory Advocacy

We work with companies and industry organizations on legislation, agency rulemaking, regulatory policy, and government relations affecting their businesses.

Working With LL&S

Clients contact us at different stages of their businesses. Some are negotiating their first major commercial agreement, while others are established organizations facing new regulations, expanding operations, or evaluating a transaction.

We welcome conversations with companies and business leaders seeking legal counsel who understands their industries and the decisions they face.

“Practical counsel for complex industries.”
