Rosemarie has been in the Real Estate business for upwards of 20 years. Already an accomplished and successful entrepreneur, she runs her own real estate brokerage, New America Realty, and a mortgage company, MD International Marketing Group, Inc. She knows the market in and out here on the Central Coast of California and is fully dedicated to her job. Rose is the Local Expert in Santa Maria, as seen on®. She is also a notary public making it a complete and full-service real estate company. Rose holds a Bachelor's Degree in Journalism/Communication and graduated with the prestigious honors of "Valedictorian" in her class.
Her goal is to make every real estate transaction as easy as possible for every single client. Always willing to go the extra mile to find the right home for each family, ensuring a smile is on their face afterward. For Rose, it's always a wonderful feeling whenever a client turns into a lifetime friend. She takes pride in having mostly referrals, repeat business, and past clients’ family members as her clients. Her relationships with them don't just end at closings nor are they just one-time transactions. She continues to be there for them even after all the papers have been signed, which is a testament to how much she places great value on maintaining long-term relationships with her clients.
In 2021, Rose faced another milestone in her long list of accomplishments as she faced an array of 18 equally business-minded and successful women in the Mrs. Philippines-Universe competition. She represented the Province of Aurora, won the Mrs. Pearl of the Orient 2021 title, and will be representing the Philippines in the 2022 Mrs. Universe pageant to be held in South Korea in July 2022. She garnered the most votes in Vantle’s Mrs. Universe-Philippines poll and has been featured in several publications including Ganap International, Fashion Art Media, and Legacy One Luxury Magazine.
Rose’s goal is to build an unshakeable brand and become the most trusted, sought-after business in her field. She believes that trust is a key indicator of business success, and her success stories are not just hers but her clients’ success stories as well. These client reviews affirm that she’s onto something.
Please contact Rose for any of your Real Estate and Mortgage needs.
