Cetera Welcomes Former Commonwealth Advisor Mark Yatros and His Allegiant Wealth Strategies Team with Approximately $176 Million in AUA

Independent advisor joins Cetera's Summit community after nearly a decade with Commonwealth, citing Summit's strong cultural alignment with the Commonwealth experience

SAN DIEGO, May 20, 2026 /PRNewswire/ -- Cetera welcomes financial advisor Mark Yatros and his Michigan-based practice, Allegiant Wealth Strategies, overseeing approximately $176 million in AUA¹. He spent nearly a decade affiliated with Commonwealth Financial Network before joining Cetera's Summit Financial Networks community after a year-long, comprehensive evaluation of the independent broker-dealer landscape.

Allegiant Wealth Strategies is a full-service advisory practice serving a predominantly retired client base, with a focus on generating reliable income and managing long-term financial security. He leads a four-person, fully licensed team and brings 35 years of industry experience to his practice – a tenure that has instilled a deep, client-first philosophy he describes as foundational to everything he does.

Like many Commonwealth advisors, he re-evaluated his broker-dealer affiliation following the announcement of LPL's acquisition of Commonwealth. For him, the decision came down to a straightforward set of priorities: personal service, accessibility, and a community of like-minded professionals.

"Commonwealth was extremely advisor-focused, and they had that small-firm feel," Yatros said. "In my experience, as broker-dealers get larger and larger, you get further and further away from the people who matter most to supporting your business. I've already been at another large firm before, and I didn't want to go back to that structure."

He spent an entire year researching and speaking with multiple broker-dealers before making his decision. His conclusion was clear – the advisor focus and flexibility, such as maintaining Fidelity's NFS for custody and clearing, made Cetera and Summit the compelling choice.

"Summit is the closest that I found to Commonwealth," Yatros said. "The main appeal with Cetera and Summit was knowing that if I call (community leader) Marshall Leeds, he's going to pick up the phone and help me with whatever I need, and he knows who I am. That's the kind of thing that sets Summit apart."

Beyond service levels, he was drawn to Summit's selective, membership-style culture, which is something he says directly parallels what made Commonwealth special.

"One of the main appeals of Commonwealth was that it was like a membership – not everyone could get in," Yatros said. "Only the best advisors were allowed to be part of Commonwealth, and there was a reason for that. Cetera has done the same thing with Summit, and those are the people I want to be affiliated with."

He also emphasized that maintaining independence and flexibility were non-negotiable in his search. After years at Commonwealth, he was unwilling to sacrifice accessibility and a direct line to leadership in exchange for the scale of a mega-firm.

"It was about being able to maintain our flexibility, our independence, and our ability to be heard without a lot of noise from 30,000 or 40,000 other advisors," he said.

Welcoming the Yatros team, Cetera Advisor Channel Leader Tom Halloran said, "Mark embodies exactly the kind of advisor Summit was built for – seasoned, client-focused, and deeply committed to doing business the right way. His experience at Commonwealth, and the premium he places on personal service and accessibility, aligns perfectly with what Summit's culture is all about. We're proud to have Mark as part of our community and look forward to supporting him and his team for the long term."
