Mercer Advisors' Martine Lellis Transitions to Support the Company's M&A Partner Development Growth Efforts

Fast-growing national RIA firm bolstering M&A team with an experienced executive, skilled in unlocking the full potential of partner firms

DENVER, May 15, 2024 Mercer Global Advisors Inc. ("Mercer Advisors"), a national Registered Investment Adviser (RIA) firm, announced the move of Martine Lellis, Chief Talent Officer since 2020, to a newly created role of Principal, M&A Partner Development.

Adding another executive with C-Suite experience to the M&A Partner Development team reflects the company's strategic commitment to inorganic growth and helps ensure the success of firms that partner with Mercer Advisors. In 2016, the company started its M&A effort. In 2017, the M&A Partner Development focus was strengthened when Dave Barton transitioned from the role of CEO -- which he held for nine years, from 2008 through 2017 -- to a newly created role of Vice Chairman focused on M&A.

Our C-Suite approach to the leadership on our M&A Partner Development team is grounded in connecting the principals of firms considering selling their businesses with executives who have built, run, and guided the evolution of an RIA themselves.

Mercer Advisors has become one of the leading RIA acquirers with over 85 acquisitions since 2016. The firm's "integrate not aggregate" strategy appeals to RIA sellers seeking to advance the client and employee experience through joining a firm with national scale and reach. Lellis is the newest addition to the expanded M&A team that Barton continues to lead. See Mercer Advisors Add Five Industry Veterans.

"We recognize that owners of RIA firms have many options and care deeply about the impact on their clients, employees, and themselves," said Dave Welling, CEO of Mercer Advisors. "Our C-Suite approach to the leadership on our M&A Partner Development team is grounded in connecting the principals of firms considering selling their businesses with executives who have built, run, and guided the evolution of an RIA themselves."

"Martine's deep understanding of our client and advisor experience, as well as her years of building, developing, and growing our talent, make her an invaluable asset in identifying and integrating like-minded firms into our organization," added Welling. "Our deep bench at the senior leadership level also allows us to make these types of transformational changes without business interruption."

"M&A is one of the indispensable ways that we build the organization's talent, experience, and capabilities. I couldn't be more excited about representing Mercer Advisors in the industry and working with other RIA owners to discover the best option for themselves, their employees, and their clients. As an integrator, not an aggregator, we seek to leverage all the talent of partnering firms. Talent mapping, career pathing, and compensation are critical to both the decision-making process and integration success," said Lellis.

Lellis has a nearly two-decade career in the independent wealth management space, a distinct accomplishment in an emerging industry. Lellis began her wealth management career at Sullivan, Bruyette, Speros & Blayney in 2002 and progressed to become the COO, overseeing a rapid period of growth for one of the industry's most well-known and highly respected RIA firms at the time. Lellis has advanced designations in financial services, including a CPA license and the CFP™ marks, as well as having earned an MBA from Georgetown University and a B.S. in Mathematics from Duke University.

Mercer Advisors has activated a national search for a Chief Talent Officer to replace Lellis in her prior role.
