What do you focus on?

Restrictive Covenants (Non-Compete Clauses) and Trade Secrets

An increasingly vital and important aspect of my work is assisting clients with protecting their valuable and highly sensitive business information through the use of restrictive covenants.  An equally important part of my practice involves helping my clients remain competitive by hiring skilled and knowledgeable employees who may be subject to restrictive covenants.  I regularly advise clients on the enforceability of restrictive covenants, in relation to hiring new restricted employees, and I assist clients with crafting effective policies, procedures, and agreements to ensure that their trade secrets are adequately protected.

Commercial Litigation

I represent corporate clients in disputes and litigation involving all manner of commercial claims, such as breach of contract, breach of restrictive covenants, theft of company trade secrets, tortious interference with contracts, fraud, unfair competition and deceptive trade practices. I have worked in many different sectors, such as banking and finance, health care, communications, technology, construction, insurance, travel, retail clothing and apparel, trucking and transportation, alcohol and beverage and food service, manufacturing and film and media production and distribution.

Health Care Litigation

I routinely represent health care providers in commercial disputes and in health care-specific matters related to the regulated health care industry, involving issues like physician privileges/medical staff challenges, physician contract disputes, including breach of restrictive covenants, vendor contract disputes, mental hygiene proceedings and guardianship proceedings related to the facilitation of patient decision-making processes and/or medically necessary procedures.

What do you see on the horizon?

As the current administration eases current regulations in various business sectors and modifies the health care laws, I believe that transactions and activities will increase, which can result in additional exposure to litigation. Clients in this new market need attorneys who are able to understand their business needs and goals and who can integrate them within dispute resolution strategies and complex litigation tactics, when necessary.
