Lathrop GPM Bolsters its Missouri Trusts, Estates & Legacy Planning Team with Addition of Two Attorneys


KANSAS CITY (February 14, 2024) – Lathrop GPM is pleased to welcome seasoned counsel Peter LeBlanc, Jr. and associate Kevin Mason to the firm's Trusts, Estates & Legacy Planning Practice Group. LeBlanc joins in St. Louis and Mason in Kansas City. Their arrival deepens the practice group's bench of more than 30 lawyers and nine legal professionals, building on its reputation as one of the largest, most renowned and established groups in the Upper and Central Midwest.

LeBlanc brings more than a decade's worth of experience in advising individuals and families on estate, trust, tax, business entity and legacy planning, including tax administration and legacy development. He joins Lathrop GPM from a boutique law firm focused on family wealth advisory and legal services.

Mason advises clients on estate planning and administration, wealth preservation, and trust and estate litigation. He assists in the creation of wills, revocable trusts, irrevocable trusts, charitable trusts, pre- and post-marital agreements and the use of lifetime gifting. Prior to joining Lathrop GPM, he was most recently an associate at a large multinational law firm and previously a trust advisor at UMB Trust Company.

"The experience and capabilities Peter and Kevin bring to our growing practice further strengthen our team's ability to continue serving our clients for many years to come," said Marya Robben, partner and leader of Lathrop GPM's Trusts, Estates & Legacy Planning Practice Group. "Both lawyers will strengthen our dynamic, multi-disciplinary practice, bringing more depth to our Kansas City and St. Louis teams. We're delighted to have them on board—and I'm certain our clients will be, too."

LeBlanc and Mason's arrivals follow other recent growth within the Trusts, Estates, and Legacy Planning team: the group welcomed associate Andrew Biddison to its Minneapolis office in August and celebrated the promotion of Jim Thomson to partner in January.

LeBlanc earned an LL.M. from the Washington University in St. Louis School of Law in 2009, a J.D. from Saint Louis University School of Law in 2008, and a B.A. in English Literature from Santa Clara University in 2000. Mason earned his J.D. from the University of Missouri School of Law in 2020 and his B.S. in Biology from Lindenwood University in 2015.
