Sonia began her career in real estate in 2001 as an Office Administrator with a brokerage company in Willow Glen. After a year’s time she took on the additional role of  Transaction Coordinator.  Working these two positions has given Sonia the knowledge and organizational skills to help her agents with their specific needs, as well as keep them and their files highly organized.  This opportunity paved the way for Sonia to fall in love with real estate. She enjoys being in the mix of each transaction and helping make the dream of owning a home a reality.  In 2004, she and her then fiancé Scott were able to purchase their own first home and start to create their lives together with a new puppy in tow.  In 2006 she and Scott were married, then in 2008 welcomed their beautiful daughter Brooke Lynn.

Before joining Sereno Group, Sonia worked for two radio stations in downtown San Jose.  In this position Sonia worked closely with management and executive staff to support the Advertising Sales Team.  This position was a great fit for Sonia’s passion for helping others, with the added perk of being able to meet and enjoy the talents of so many successful musicians. After taking a break to care for her daughter, she soon took the initiative to pursue a career in real estate.  

In 2013 Sonia joined the Sereno family as the Transaction Coordinator of our flagship office in Los Gatos.  During that time she worked closely with over 40+ agents closing approximately 400 files a year. Sonia has built lasting friendships with all of her agents and made sure they felt like she was only working for each of them.  Sonia takes great pride in her work ethic. She strives to make everyone’s needs a priority while getting things done the right way so they can focus on the building of their business.  Sereno Group has been growing and Sonia was considered herself a lead in her craft. She wanted to do more with her role to help support management and her fellow TC’s.

In July 2018, Sonia became the Director of Transaction Coordination. She is part of our Leadership Team and works closely with our VP of Risk Management to oversee the dynamic and talented Sereno TC Team.  With Sereno growing we needed a new position to help with the back end of all that goes into making sure our TC’s are trained to do their jobs efficiently as well as making sure our files are complete and in compliance. Together Sonia and Raylene are revamping the TC platform to help with training,  efficiency and streamlining all processes for transparency and consistency from one office to the next.

Sonia is always willing to lend a helping hand to our office staff and agents all while keeping a smile on her face and a positive attitude.  She is hard working, a team player and takes pride in Sereno Group and the culture it upholds with both agents and staff.  Sereno’s commitment to better the community with the 1% For Good campaigns is one that cannot be replicated anywhere. 

Another love Sonia has is for her New York Yankees...she is a huge fan!

Sonia lives in Willow Glen with her husband Scott, daughter Brooke and 2 fun loving, silly boxers. She loves spending time cheering on her daughter at her swim events year round.
