REAL ESTATE2 weeks ago

Mariana Niro’s path to becoming one of Miami’s most influential real estate agents is a story of grit, vision, and unwavering drive. Originally from Brazil, Mariana relocated to the vibrant city of Miami in 2000. She began her professional journey in finance spending over a decade and a half at prestigious firms including Credit Suisse First Boston, Prudential Securities, and Wachovia Securities where she honed her expertise as a trusted financial advisor.

In 2005, she pivoted her career by earning her real estate license and diving headfirst into Miami’s competitive real estate scene. Guided by a sharp financial mind and client-first philosophy, Mariana quickly stood out, especially among international investors seeking luxury properties in Florida.

Today, as a founding agent at SERHANT. Miami, she ranks in the top 1% of agents nationwide and has surpassed $1 billion in total sales an incredible milestone that solidifies her reputation in the industry.

A Champion Agent with Award-Winning Credentials

Recognition has followed Mariana at every turn. Early in her real estate career, she earned Douglas Elliman’s Platinum Award and was ranked among the Top 5 Producing Agents in both 2014 and 2016. In 2015, she was crowned the #1 agent for Coconut Grove & Brickell two of Miami’s most prestigious neighborhoods.

Her influence extended beyond sales: in July 2016, REAL Trends named her the Best Real Estate Agent in Florida, and Mastermind listed her among the Top 100 Most Influential Real Estate Agents of the year. Fast-forwarding to 2019, she earned Douglas Elliman’s Pinnacle Award and landed in the top 2% of agents nationwide.

Moreover, according to the RealTrends Verified database, based on 2024 sales data, Mariana closed 46 sides totaling approximately $120.47 million in volume, ranking her 25th by volume and 153rd by sides in Florida.

The Hustle Behind the Headlines

Behind the awards and glossy listings lies a story of determination. Navigating a competitive, fast-paced luxury market isn’t easy, but Mariana turned early financial setbacks into fuel. Her strategic mindset, attention to detail, and client-focused service helped her transition smoothly and scale quickly in real estate.

Language savvy, cultural insight, and empathy likely shaped by her immigrant experience made her especially effective at working with international investors. She not only sold them homes, but offered guidance, reassurance, and long-term vision.

Her success proves that a solid foundation in finance can cross-pollinate well with real estate especially in Miami, where investments and luxury often intersect.

A Life Changed, A New Mission

But recently something major happened in Mariana’s life that reshaped her mission. She lost her entire family10 beloved members including her mother, two sisters, four nieces, one nephew, and two brothers-in-law in a tragic plane accident in Brazil. The plane crashed and exploded, leaving an unthinkable void. It’s been only eight months since the tragedy, but instead of letting grief stop her, Mariana found a higher purpose.

After the accident, she began coaching realtors to help them get to the next level and grow their business as a form of giving back and volunteering. Real estate is what she knows best, but more than sales and rankings, she now teaches that success is not defined by being among the top agents it’s about having balance in life. For Mariana, true achievement lies in nurturing the most important pillars: health, family, friends, and financial stability.
