ZeroCelsius Wealth Studio, which oversees about $134m in assets, was founded in 1998 and rebranded in 2009.

The firm has been led by managing partner and wealth advisor Ross Gott and operations manager Robin Laughinghouse.

Gott said: “Expanding our partnership with Carson Group allows us to stay true to who we are while ensuring the firm is built to last.”

“For Robin and me, this decision came at the precise moment when the conditions were right to thoughtfully evolve the business with our trusted partner. We believe deeply in living and planning life with intention and clarity. This partnership provides the scale, resources and long-term support needed to do exactly that. Most importantly, it helps ensure the clients and families who rely on us will continue to be served with care, purpose and consistency for generations to come.”

ZeroCelsius had operated independently until October 2023, when it became a direct partner of Carson Group.

Gott cited alignment with Carson’s culture and approach to client service, as well as the group’s resources for investment research and planning, as key factors behind the decision to join.

Since partnering with Carson, ZeroCelsius has broadened its access to investment products, financial planning tools, and technology intended to further support its operations and client services.

Carson Group CEO Burt White said: “This is an important milestone for Carson Group as we have grown exponentially over the past few years.

“Reaching 40 wholly owned offices reflects the strength of our practitioner-led model, but more importantly, it reflects the trust advisors place in Carson to help them build enduring businesses. Each new office enables us to broaden our reach, deepen our impact and continue delivering personalised financial guidance to clients across the country. It’s clear that Ross and Robin have built something deeply personal and purpose driven. Our role is not to change that spirit, but to strengthen it with the scale, systems and long-term support that helps ensure their clients thrive for generations to come.”
