Cambridge Properties is expanding its advisory bench with the addition of Aaron Carter and Mike Mosier, founding partners of CarterMosier Group, a move that reinforces the brokerage’s long-standing emphasis on relationship-driven real estate in Arizona. The Phoenix-based duo joins the firm with approximately $200 million in closed residential sales and decades of combined local market experience.

For more than 30 years, Cambridge Properties has positioned itself as a Valley leader by prioritizing discretion, judgment, and long-term client relationships over volume alone. The addition of Carter and Mosier reflects a continued focus on aligning with advisors whose standards and approach mirror the firm’s ethos of thoughtful, client-first representation.
“When we were presented with the opportunity to include Aaron Carter and Mike Mosier within the Cambridge family, Keith and I were an emphatic ‘yes,’” said Cory Mishkin, COO of Cambridge Properties. “They exemplify what it means to put clients first. Their approach reflects Cambridge’s ethos of ‘Your Best Interest. Always.’ We have known both for years, and their clarity, discipline and sense of responsibility to clients are exactly what we value. We are thrilled to welcome them to Cambridge.”

CarterMosier Group built its reputation on a referral-driven practice across Arizona, advising buyers and sellers through complex transactions with a measured, strategic lens shaped by experience in design, development, and residential real estate. That background allows the team to approach deals not just as sales, but as long-term decisions that intersect with lifestyle, investment, and neighborhood dynamics.
Their decision to join Cambridge followed a deliberate search for a boutique brokerage that aligned with their client-first standards while providing the stability, leadership, and infrastructure of an established platform. Cambridge’s blend of expertise, luxury focus, and entrepreneurial culture made it the right fit.

“This move is about shared timing and long-term vision,” Carter said. “Working alongside Cambridge Properties continues our relationship-driven approach, backed by a brokerage partner that shares our outlook, demonstrates a commitment to local markets, and brings a client-focused mindset.”
Carter and Mosier are also known for involvement beyond transactions, including HOA governance, neighborhood preservation, and long-standing relationships with vendors, inspectors, lenders, and title professionals. Together with Cambridge, they will continue advising clients in both the Phoenix and Tucson metro areas. Learn more at cartermosiergroup.com.
