A team of Phoenix luxury agents that has surpassed $1 billion in sales volume has joined Local Luxury Christie’s International Real Estate.
Maximilian de Melo and Patrick Niederdrenk, formerly of America One Luxury Real Estate, will join forces with Katrina Barrett, the broker and owner of Local Luxury. The Local Luxury team is affiliated with Christie's International Real Estate, but it is owned and operated by Barrett.
The move became official Dec. 5. de Melo and Niederdrenk brought 12 additional agents from America One Luxury to Local Luxury.
In an interview with Homes.com, de Melo said he and Niederdrenk both grew up in Germany, where they became friends and business partners. The two moved to Arizona in 2017 and bought into America One, which was operating as a property management company at the time.
Niederdrenk got his real estate license in 2018, launching the real estate transactional side of the business. The next year, de Melo got licensed.
In the seven years of operating America One Luxury Real Estate, the collective team eclipsed $1 billion in sales volume.
In a statement, Barrett said the team's move to Local Luxury "creates one of the strongest luxury real estate alliances in Arizona."
New team boosts Phoenix's top luxury markets
In 2025 alone, the team had a sales volume of just under $100 million across 29 deals. Of those deals, more than 40% were off-market transactions. The two are expected to bring over $175 million in luxury inventory into the new partnership.
de Melo said the team specializes in representing developers and builders in top luxury markets like Scottsdale and Paradise Valley.
"Patrick and I, we've worked 24/7 ever since we stepped foot in this country in 2017. That's part of our brand," de Melo said in an interview with Homes.com. "I think that draws clients in and drew the team in that we built around us."'
De Melo said the move to Local Luxury was driven by the "need to get to the next level." He said the Christie's platform and the Local Luxury team increase access to discerning buyers, investors and high-net worth individuals around the world.
“This is more than a brokerage move,” Niederdrenk said in a statement. “It is a strategic evolution of who we are, how we serve, and the scale at which we operate."
