Areas of Focus

Health Care Law
Constant flux at the federal and state levels of government, along with unprecedented market activity, present health care providers with daunting financial and regulatory compliance challenges as well as major opportunities. This synergy has created a niche where John’s particular skills come into play. His intricate knowledge of business problem-solving and translating complex information in terms his clients can understand work to create long-term relationships. John’s experience in the medical and dental fields provides his clients with legal and strategic advice that incorporates compliance, coding, audits, group dynamics and transactional practice.

Health care providers are trained to diagnose and treat patients, but now that health care is an extensively regulated business, providers need attorneys skilled in the regulatory and business aspects of health care. From launching new businesses and setting up facilities to the structuring of tax and financial details that optimize success, John provides a seamless experience that extends to implications for personal and family matters. Leveraging the depth and scale that has made Wilson Elser one of the nation’s most influential law firms with a comprehensive roster of legal services, John can give each client the best of the firm’s collective intelligence and capabilities.

Tax Planning & Controversies
From partnership and corporate tax to pension planning, John advises on and implements strategies designed to achieve successful transactional goals, including succession planning and a range of related issues. He is adept at “troubleshooting” delicate situations, such as family politics and partnership disputes, providing resolutions that stand up to challenges and the test of time.

Commercial & Private Real Estate Transactions
John offers substantive value to real estate clients by taking an integrated approach that draws on his experience with transactional real estate and related tax matters, complex real estate deals, commercial leasing, and single-family homes and apartments. As a member of the firm’s transactional real estate group, John handles an array of matters for sellers and purchasers, calling on his experience, reputation and skills to guide them efficiently through the process. In light of the real estate industry’s continued integration with the capital markets and its increased vulnerability to litigation, he frequently collaborates with attorneys in the firm’s Bankruptcy, Municipal/Local Government and Environmental services, among others.
