Outside GC Expands Boston Area Legal Team

Outside GC, the nationʼs leading provider of on-demand, in-house legal counsel services, announced today the expansion of its Boston-based group with the arrival of three new members of the firm – Susan Antonio, Jodie Vasily-Cioffi and Jill Zimmerman-Diaz – adding substantial life sciences, health care, investor and growth company experience to the team.

Susan Antonio joins Outside GC from Saturn Partners, a Boston-based venture capital firm, where she spent the last 13 years as Chief Legal Counsel and General Partner. Susan will leverage her experience from both the legal and investor perspective to work with Outside GC’s growth-stage clients, as well as clients that invest in growth companies. Susan’s initial clients at Outside GC include a West Coast-based broker dealer, a fast growing venture-backed sports business based in Boston, and a leading growth-stage technology company about to seek its first institutional funding.

Jodie Vasily-Cioffi joins Outside GC to work with the firm’s growing list of bio-pharma clients. Jodie’s 15 years of experience advising life science companies, including 10 years in-house at Genzyme Corporation, where she handled a wide-variety of corporate legal work, including public company and operational legal work, make her ideally suited to act as on-demand, in-house counsel to both public and private life sciences companies. Jodie’s initial Outside GC clients include a medical device company that recently had a successful IPO.

Jill Zimmerman-Diaz has served clients in the life sciences and healthcare space and possesses extensive litigation oversight experience. For a decade, Jill served as General Counsel/Compliance Officer for a healthcare services company and has knowledge of Medicare, Medicaid, False Claims Act, electronic health records, and HIPAA.  For over three years, Jill represented American Express, Discover Bank, Bank of America, and other national banks, to create a litigation program involving over 25,000 commercial lawsuits in 28 states during a time of intense regulatory scrutiny.  In addition to her general business clients, Jill has represented multiple pharmaceutical, medical device, and healthcare clients, and one of her initial Outside GC clients includes a multi-national pharmaceutical company.

“The Boston-area market is exploding with new business opportunities, particularly in the life sciences and high tech industries,” explained Bill Stone, managing member of Outside GC. “Susan, Jodie and Jill each bring significant experience in these areas and add immediate value to our ability to meet the demands of our growing client base.” Stone added, “Outside GC’s continued growth, not only in Boston but also in New York, D.C. and Denver, further validates the market need for an alternative to relying exclusively on traditional law firms for legal support. Our team members have the same level of legal and business expertise as partners at premier law firms, but we also provide the added advantages of significant in-house experience, hourly rates at a fraction of what large firms charge, and a client experience that only a flexible, on-demand model can offer.”

Stone further noted that Outside GC’s success is linked to its ability to recruit top-notch talent. “Our model is uniquely appealing to lawyers looking for the right balance between a fulfilling professional career and time for other important connections in their lives,” explained Stone. “Indeed, all three of our new team members support or have founded non-profit organizations, and chose Outside GC in large part because we value commitment to community and give our team members the freedom to pursue these passions.” Jodie Vasily-Cioffi concurred, “I am thrilled to be joining the Outside GC team. Outside GC offers me the opportunity to work with exciting companies and great colleagues, along with the flexibility to continue working on behalf of children with dyslexia.”
