Meet Debbi

Debbi DiMaggio | Piedmont to Beverly Hills



Author, Real Estate leader, mom and philanthropist Debbi DiMaggio is a master marketer, community builder, and tech-savvy guru who embraces the fast-paced Real Estate market. A Realtor in the top 1% of all Real Estate agents nationwide, Debbi has also authored three books, Contained Beauty (2012), The Art of Real Estate (April 2015), which she co-wrote with husband/partner Adam Betta and Real Estate Rules! 52 ways to achieve success in real estate (April 2016).

Aside from selling Real Estate full time, Debbi along with her husband Adam Betta, two of the Partners at HIGHLAND PARTNERS a Top Producing Firm located in the East Bay of Northern California since 2009, when they purchased the company in the downturn, a bold move indeed. Adam is the Broker while Debbi keeps things exciting as the Marketing Director where she oversees 100 agents assisting them with their marketing and business goals through mentoring and coaching.

Debbi and Adam’s VIP Philosophy includes treating everyone like a VIP from the contractors (plumbers, painters, interior designers) to movie star clients (Julianne Moore, Ted Danson, Sally Field, and Director, Chris Columbus to name a few). As San Francisco Bay Area Realtors and two of the three founders of HIGHLAND PARTNERS, Debbi DiMaggio and Adam Betta are proud to share that HIGHLAND PARTNERS, was voted Best Real Estate Agency in Oakland Magazine's 2014 Best Of Oakland and the East Bay. Furthermore, this dedicated duo, has been consistently honored, year after year with the Top Producing Team Award in the Better Homes and Gardens Mason McDuffie family, a California-based company comprised of 28+ offices.

Since their two children, now young adults went on to create lives of their own, their daughter now a Realtor in New York City at Engel & Volkers on Park Avenue and their son a student at CU Boulder, Debbi decided the time was right to expand their Real Estate footprint into Los Angeles. And as it goes, timing is everything, and that is when she met her LA Real Estate partner, Justin Fierro. Debbi and Justin met at a charity event she was hosting for Voices 4 Freedom, an organization seeking to raise funds to free villages from bonded slavery in India and other oppressed countries. Elated with the outcome of that evening the team raised enough to fund 3 schools for one of their primary programs, Schools4Freedom which focuses on education as a way out of slavery. “We know that one of the best ways to get people out of slavery, keep them out, and to prevent others from ever being enslaved in the first place is through educational programs.” It’s no wonder Debbi and Justin crossed paths at that time, real estate conversation and charitable causes, two of Debbi’s passions under one roof, what could be better.

Debbi first received her Real Estate license in Los Angeles where she worked with Coldwell Banker in Hancock Park. Now 25 years later she is back. Debbi has always felt connected to LA and knew one day she would return.

As her husband knows all too well, Debbi is a force to be reckoned, with an attitude, “you can rest when you die,” and as Justin notes, “I am enjoying our partnership, but am not too proud to admit, she does not sleep and is keeps me on my toes.” “Debbi always has more going on in her one pinky than most have in their entire lives; she makes most of us look like we are standing still.” “I hesitate to say that, however, because she does not mean to make anyone look or feel bad, it is simply her nature,” and as I have been told by her husband, “has been ever since she was a young girl.”

Together, Debbi and Justin definitely keep busy, working hard by day and networking by night, with no shortage of events to attend. From managing her family household, her Real Estate career, in both Piedmont / the Bay Area and Beverly Hills / LA, working with two start-ups on two different Apps, two more books in the works, non-stop travel and numerous charities to which she is involved, just may begin to paint a picture into the life of Debbi. People often ask, #WheresDebbi?

Her work has also been featured by Luxury Real Estate, KGO 810 Consumer Talk Radio Show with Michael Finney, KDOW 1220 AM Real Estate Radio Live with Joe Cucchiara, East Bay News, Oakland Magazine, Unique Homes Magazine and on KRON4 TV.
