Rosemarie Sire

Meet Rosemarie Sire – The Heart Behind the Sire Team

Welcome to the Sire Team at First Team Real Estate — your trusted resource for all things real estate in Huntington Beach and surrounding communities. For over 40 years, I’ve had the honor of helping families buy and sell homes across Orange County, with a strong focus on neighborhoods I know intimately — including Glen Mar East, Glen Mar West, Glen Mar Big, Glen Mar Little, Park Place, Oceanwood, Seabury, Century Shores and greater Huntington Beach.

My journey in real estate began in 1980, working side by side with my husband, Joe Sire, after he completed a new home development project in Century Shores. Together, we built a business rooted in integrity, community, and relationships. As we raised our daughters, we stayed actively involved in local schools, parks, and small businesses — always believing that strong families and strong communities go hand in hand.

After Joe’s passing in 2012, I chose to continue the Sire legacy by partnering with a trusted friend and colleague, Dani Walker. Joe personally mentored Dani when she began her career over 24 years ago, and she brings the same passion and professionalism to the table. Our partnership ensures that the Sire name and values live on — serving both first- and second-generation clients with honesty, heart, and results.

Throughout my career, I’ve been honored to receive:

Over 40 Years of Full-Time Residential Sales Experience
First Team Hall of Fame Annual Award Winner for Over 30 Years
Hall of Fame Gold Medallion Award Recipient
First Team’s Special High Sales Volume Recognition
Backed by First Team — Orange County’s #1 Selling Real Estate Firm for Over 25 Years

"We were referred to Rosemarie and Dani for the sale of our parent's home after losing our mother in January. It was a very emotional moment to go through and clear their home of 55 years. We were so thankful for their referrals to contractors that we could trust. After listing the home we received over 8 bids in a matter of days. This was the fastest and easiest home listing that any of our family ever experienced. We are so appreciative."

John M.

"The transaction could not have gone any smoother."

James M.

"Rosemarie Sire is an excellent realtor (5 stars). She is very knowledgeable and reliable in helping us to buy the property on summer ln successfully. We look forward to doing business with her again in the future."

Huy T.

"I recently had the good fortune and pleasure to work with Dani walker-brown and Rosemarie Sire regarding the sale of my mother's property. Dani and Rosemarie are truly experts in the area and helped me get $100000 over the asking price as the first offer during the first open house weekend. My mother had lived in this house for almost fifty years and only minor maintenance was made during her occupation. Extensive upgrades were required based on comparable homes in the neighborhood in order to justify the asking price let alone the final selling price. Dani and Rosemarie guided us in the decision of what to upgrade style contractors' materials and color palettes. The end result of their guidance and experience was $10000 over the asking price which more than paid for the renovations. I cannot recommend Dani, Rosemary, and the entire team at FirstTeam enough for their knowledge professionalism, and attention to detail; so much so that I engaged them to be my buying agents for a rental property. I am very satisfied with both transactions and I highly recommend Dani and Rosemarie to anyone looking to buy or sell real estate; save yourselves time and headaches just go with Dani and Rosemarie you will not be disappointed."

Patrick K.

"Rating: Excellent I would give more stars if possible. Rosemarie guided my family and me during a very difficult time as our father passed in April of 2022 and we needed to file documents for their trust and have a reassessment of my mother's home. Rosemarie educated me on the process and gave me the tools and sites that lessen my anxiety to take on this heavy responsibility for my family. Having a caring person understand the situation eased my burden. I would highly recommend her to anyone having real estate dealing as she has the knowledge and experience but most of all she is a kind honest and caring person."

Margy K.

"Roe is a true creator of masterpieces! Living in Huntington Beach all my life and enjoying the times I ran into Roe and Joe working in our community ( always giving back ) I always knew that Roe would be the one to sell our home when we decided to In which we did. And what a wonderful job she did putting her heart mind and soul into it. I am now waiting for the next Masterpiece to be completed ( finding my retirement home ). Mahalo Roe for all your hard work! Collette."

Collette W.

"After working with Rosemarie it became very evident that all real estate agents are not created equal. I have lived long enough to realize that we must obtain the expertise of a trusted local agent but after emerging from a seamless home selling environment I realize that Rosemarie goes above and beyond. She brings along many years of professionalism along with being very tech savvy but her truthful upfront and balanced personality is something very comforting and comes only from the heart. I not only gained a highly experienced agent but also a friend."

Sylvia T.

"When my father passed away I called Rosemarie to sell his home. Being from Washington state this could have been very difficult. Rosemarie took care of me by contacting all her unlimited resources to get the house ready for the market. Rosemarie was a rock I leaned on during this difficult time. She has been our realtor on both our family homes. Her years of experience shines through."

Starr W.

"Joe and Roe have always worked in our neighborhood always working at giving back to the community I always knew it would be the Sire team working with my neighbors in previous years everyone I knew sold and bought new places they enjoyed! That speaks volumes the best experience until my wire was almost routed to who knows how my husband's good faith check was copied and his personal information compromised to open up accounts out of state. Overall all good experience? Thanks, Rosemarie sire for this."

Collette W.

"Living in HB since 1971 The Sire Team Joe and Rosemarie we're one of the first to begin relationships with our neighborhood. I got quite a bit of work out of their newsletter as well. Our neighbor used Roe as her agent and was extremely pleased with her experience with Rosemarie as her agent. Myself moving from homeowner to condo owner my experience went perfectly, and not by sheer luck! Many Thanks to Roe for her hard work professionalism and dedication!"

Daryl W.

"Rosemarie is the professional/professional! We interviewed and she got us the best price and coordinated the moving process seamlessly! Good experience; highly recommended."
