Jeffer Mangels Butler & Mitchell LLP is pleased to announce the addition of two new partners in its San Francisco office: insolvency lawyer Bennett Young, previously of Dewey & LeBoeuf and environmental lawyer Jon Welner, formerly of Paul Hastings and Downey Brand.

Young has more than 30 years of experience representing clients in insolvency matters. He is a former Chair of the California State Bar’s Insolvency Law Committee, is a past president of the Northern California chapter of the Turnaround Management Association and has been a member of the Bench-Bar Liaison Committee for the United States Bankruptcy Court for the Northern District of California and of the Board of Directors of the Bay Area Bankruptcy Forum. He received his J.D. from Hastings College of the Law and his B.A. from the University of California, San Diego. 

“I have known the bankruptcy lawyers at Jeffer Mangels for many years and they are a first-rate group of skilled practitioners,” said Young. “It is a great pleasure to become their partner.” 

Jon Welner has more than 15 years of experience representing clients in all areas of environmental and natural resource law. He represents manufacturers, project developers, renewable energy companies, biotechnology companies, waste disposal and recycling facilities, financial institutions, and a wide range of other businesses on their most pressing environmental matters. He has special expertise in conducting legal audits and developing compliance systems, and in the early transfer and redevelopment of former military bases. Welner also represents clients on complex “prevailing wage” and public contracting matters. (Prevailing wage laws regulate the wages paid to workers on publicly funded construction projects.) Welner is on the Executive Committee of the Environmental Law Section of the Bar Association of San Francisco and numerous nonprofit boards including the Board of the Osher Marin Jewish Community Center. He is a Planning Commissioner of the Town of Tiburon. He received a J.D. from Stanford Law School, where he was Associate Editor of the Stanford Law Review, and a A.B., with Distinction, from Stanford University. 

“JMBM’s regulatory and land use practice is among the best in the state,” said Welner. “It offers a great platform from which to serve my clients and continue to grow my practice.” 

“JMBM offers a strong and stable business platform that actively helps lawyers build their practices with confidence,” said Richard A. Rogan, Co-Managing Partner of JMBM’s San Francisco office. “We continue to add self-supporting attorneys with the experience and scope to serve the legal needs of the business and financial community.”
