Cetera announced that financial advisor Mark Yatros and his Michigan-based practice, Allegiant Wealth Strategies, have joined Cetera’s Summit Financial Networks community with approximately $176 million in assets under administration (AUA). Yatros previously spent nearly a decade affiliated with Commonwealth Financial Network before making the transition to Cetera Financial Group following an extensive year-long review of the independent broker-dealer landscape.
Allegiant Wealth Strategies operates as a full-service advisory practice focused primarily on retired clients, emphasizing reliable income generation and long-term financial security planning. Yatros leads a four-person fully licensed team and brings 35 years of industry experience to the business.
According to the announcement, Yatros reconsidered his broker-dealer relationship after the acquisition of Commonwealth by LPL Financial was announced. His evaluation centered on maintaining personal service, accessibility, independence, and alignment with a smaller community-oriented culture.
Yatros said Cetera’s Summit community stood out because of its advisor-focused structure and ability to preserve flexibility, including continued access to Fidelity’s National Financial Services platform for custody and clearing. He also highlighted Summit’s selective membership-style culture as a key differentiator during the selection process.
Cetera Advisor Channel Leader Tom Halloran said the addition of Yatros reflects the type of experienced and client-focused advisor Summit was designed to support. Halloran added that Yatros’ emphasis on accessibility and personalized service aligns closely with Summit’s overall culture and long-term advisor support strategy.
Cetera Financial Group said it supports approximately 12,000 financial professionals and institutions through its multi-channel wealth management ecosystem. As of March 31, 2026, the company reported approximately $630 billion in assets under administration and $296 billion in assets under management.
KEY QUOTES:
“Commonwealth was extremely advisor-focused, and they had that small-firm feel. 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.
Summit is the closest that I found to Commonwealth. 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.
One of the main appeals of Commonwealth was that it was like a membership – not everyone could get in. 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.
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.”
Mark Yatros, Founder Of Allegiant Wealth Strategies
“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.”
Tom Halloran, Cetera Advisor Channel Leader
