28th Annual Medical Device Conference
At Wilson Sonsini, we take a tremendous amount of pride in our broad range of industry conferences and programs, which are widely regarded as providing crucial, high-value opportunities for networking, business development, and knowledge-sharing. At the same time, our top priority is the health and safety of everyone involved in our events. As a result, in light of the current COVID-19 pandemic, we have made the difficult decision to cancel the 28th Annual Medical Device Conference, previously scheduled to take place in San Francisco on June 18-19, 2020.

The firm is currently evaluating the possibility of holding a scaled-back, virtual version of this year’s conference at a later date. This page will be updated with any new developments.

The cancellation of this year’s in-person event is not the outcome we had hoped for, but given our overall concern for your well-being, the current uncertainty around the end date for shelter-in-place orders, and our commitment to contributing to global, national, and local efforts to slow the spread of the virus, we believe this is the right decision.
