"Coleen helped us find our dream property on the Balboa Peninsula bay front. She also was able to convince the seller of our ability to perform which was important as there were several other bidders on the property. Coleen also helped us sell our beach front duplex in West Newport, as she secured a qualified buyer. Coleen is an extremely knowledgeable and hard-working agent and I highly recommend her services to anyone thats looking to either sell or purchase. You will not be disappointed! " - Jan & Diane, Past Clients | Balboa Peninsula

★★★★★
"Before we listed with Coleen we interviewed 5 realtors...she was first in line. We chose her because of her straight forward and realistic approach to our listing. Coleen performed as advertised...great marketing and honest dialogue as to what was best for us...weve sold and bought many houses thru the years and Coleen was our partner in this adventure...thanks Coleen to you and Bill! " - Ren Rooney, Past Client | Crystal Cove

★★★★★
"I have dealt with Coleen for the last four years and she has been more than helpful in all my requests. She has shown and proven herself to me as a true business woman with real estate savvy. I would recommend Coleen to anyone and everyone who is looking to buy or sell a home. If I owned or brokered real estate, I would want her on my team - no questions asked. " - Ed, Past Client | Newport Coast

★★★★★
"Coleen Brennan was our agent when we purchased a second home in Newport Beach. She is tremendously knowledgeable about the local market and took us from the Balboa Peninsula to Laguna with many stops in between to help us discover the style of living we prefer. She is very responsive to any requests and helped us close escrow in a matter of three weeks. We are currently looking for a buildable lot and Coleen has stepped forward with ideas for builders etc. Once again, her knowledge of the area is amazing. Coleen is the consummate professional. " - Michael & Cynthia, Past Clients | Corona del Mar

★★★★★
"My wife and I called on Coleen Brennan on two separate occasions (several years apart) for her assistance in locating a residential property to buy. In each case Coleen was conscientious, thorough, always gracious and definitely knowledgeable. Further, we found her to be very reliable and forthright in all respects. We would not hesitate to give the highest marks to Coleen for her professionalism and integrity, nor would we hesitate to recommend her to anyone who might need the best in Real Estate assistance. " - Wayne, Past Client | Corona del Mar

★★★★★
"Coleen Brennan, and her Partner Bill Forsythe, represent the best of what Real Estate brokers should be: Hungry, Experienced, Networked, Proactive, and Fierce protectors of client interests.In our case, they guided us through the sale of a unique oceanfront property, through a declining market, and got the listing sold in a few short weeks. They stayed with us through ups and downs in the process, providing us color and transparency through the interactions with potential buyers and their brokers. They also provided us with updated data along the way and candid advice on the realities of the changing marketplace.They have decades of experience between them, and the enthusiasm of a team just getting started. Would highly recommend them to represent a sale or a purchase. " - Michael Parekh, Past Client | Oceanfront

★★★★★
"The team of Coleen and Bill delivered on all promises/expectations that were set. They provided solid direction on establishing an effective strategy to list and sell our home in a timely matter, as well as for our targeted number. They are extremely responsive, knowledgeable and always act in your best interest. We have now used their services for both buying and selling a home. Highly recommend! " - Scott Clemmer, Past Client | Corona Del Mar

★★★★★
"My husband & I just picked the team of Coleen Brennan and Bill Forsythe with no prior experience or recommendation; but when we interviewed them, we were impressed with their enthusiasm and knowledge of sales in our area. They were very accommodating about not pressing us into changes & some repairs which we did not want to make, they were willing to take on the house as it was. Although it took somewhat longer to sell than any of us expected, they really hung in there and spent many many hours showing our house. When it did sell, they were still there helping with details & dealing with the buyers; even after it was officially closed. All in all, working with them was a very good experience; they made selling the house as easy and pleasant as the job of selling can be. " - Mary Alice Splendore- Bax, Past Client | Newport Beach

★★★★★
"Coleen and Bill are a great team, I walked into an open house (without an agent) and initially met Bill. I wanted to buy the property and worked with Coleen and Bill to help negotiate a fair deal for myself and the sellers where it was a win-win scenario. Coleen is very responsive and moves quickly. They are straight shooters and get it done. I'd work with them again. " - Cliff, Past Client | Newport Beach

★★★★★
"Colleen is so knowledgeable of the market. Getting you the most for your listing. But her service and work ethic is incredible. Immediate call backs, keeps you updated at all times . Seems there is nothing she hasn't seen or dealt with before. Feels so good to ride with. Having her as your advocate takes all worry or uncertainty out of selling your place. She has so many contacts and will treat you as a friend she's working for . Super person. If you like boutique service as I do not just being one of many you want to work with her. " - Scott Hayden, Past Client | Newport Beach

★★★★★
"Coleen was brought in when our first realtor had our listing for 6 months and we did not get even ONE offer. We found her on a fluke and she was EXACTLY what we needed and wanted. She is NO nonsense and will tell you how or why your current home has not sold or why you haven't found a home yet. She knows the real estate market from average priced homes ($750,000 in our case) to the luxury market (almost $5,000,000 in our case). She will not spend your money needlessly to fix-up your home for showings....she knows what makes a home more salable, based on the current market trends. When the contract with our agent we had to sell our condo expired, we again called her and she got it sold QUICKLY. She knows how to get the job done. I cannot recommend her highly enough....again, she's all business, but she does have a very good sense of humor!!!!! " - Source: RateMyAgent | February 13, 2023

★★★★★
"Coleen not only sold my Grandma's home (where I lived) in a matter of days but it was done with care and ease. Then she found my family and I a beautiful home to buy quickly there-after! She knew exactly what she needed to do in this crazy market of high house prices and low inventory! She represents you 100% by being connected and communicative, is trustworthy and very determined! The best qualities in a realtor are within Coleen. I highly recommend her-she is lovely to work with. " - Tera Alford, Past Client

★★★★★
"We have used Coleen to buy and sell residential real estate on many transactions. She is a dedicated professional who listens to what the client wants and makes it her challenge to fulfill the order. On one occassion, we wanted to buy a house in a community in Newport Beach. There were no houses listed in this community. Coleen reached out to all 150 home owners in the community and found 3 potential sellers. We bought one of those homes the very same day! She is amazing. " - Marilyn Lobel, Past Client | Newport Beach

★★★★★
"I have had Coleen sell two houses for me and both times the transactions were seamless. She pays attention to detail and handles issues quickly and efficiently. I would highly recommend Coleen to anyone interested in buying or selling property. " - Ted Baxter, Past Client | Corona del Mar & Newport Coast

★★★★★
"Coleen Brennan and Bill Forsythe have combined the best of the real estate and yachting industries. Apart they were formidable but together they offer the finest in professional representation. Whether you are looking for a residence on the land or sea, Coleen and Bill can guide you home. Experienced, passionate, focused, and fun to work with, Coleen and Bill brings decades of expertise to each transaction. By land or by sea working with Coleen and Bill will be a wise decision. " - Gary Longobardo

★★★★★
"I manage a rental property in Corona Del Mar, CA and have benefited from Coleen Brennan's services in connection with this property for about ten years. In working with her, I formed the opinion that she is knowledgeable and experienced with the real estate market in the Orange County beach area, and is prepared to assist her clients in reaching their objectives. Whenever I sought her assistance and advice, she responded quickly, thoroughly and professionally. Working with her has been a pleasant experience for me, and for all of the above reasons, I fully recommend her. " - Evelyn Feldman

★★★★★
"I have had the privilege of working with Coleen Brennan for the past 3 years and can truthfully state that she is highly respected in the industry. Her guiding values focus on Community, Compassion, Honesty, Knowledge and Reputation.I have first hand knowledge of Coleens work ethic and she is highly intelligent, extremely driven and committed to her profession. " - Cheri Kluft

★★★★★
"I have known Coleen Brennan for the past 4 years. I can honestly say she is one of the hardest working agents I have ever met. Coleen can handle any challenge you give her from marketing and selling a 50 million dollar home for the most demanding of CEOS to being a friend to a client in need. What is most rare is to see her ability to adjust and compete in the ever changing market after having years of experience. That is a very rare trait. She uses the latest technology and is already looking for ways to improve. On top of all of this she is a friend who I have come to trust deeply. I highly recommend her for whatever your real estate needs. " - Paul Benson

★★★★★
"I have worked with Coleen for sometime and find her to be a professional at all times. Coleen finds strategic and creative solutions to hurdles with success I have found most real estate professionals would avoid. I have enjoyed working with her and having her on my team and look forward to working together again in the future! " - Chris Oldham

About Brennan + Forsythe

TWO PERSPECTIVES. ONE STANDARD.

COLEEN BRENNAN & BILL FORSYTHE
Experience. Judgement. Integrity. Results.


Some real estate decisions are about a property. The most important ones are about what comes next.

Together, Coleen Brennan and Bill Forsythe bring clients an uncommon combination of real estate judgement, high-value transaction experience, deep coastal knowledge, and personal service. Their partnership is built around a simple idea: clients deserve thoughtful advice before they ever need a sales pitch.

With more than three decades in real estate and a career approaching $1 billion in transactions, Coleen has built her business on relationships that endure. Approximately 85% of her business has come from repeat clients and personal referrals - a reflection of the trust clients place in their judgement, persistence, and ability to understand not only what they say, but what they may not yet have put into words.

Bill brings a complimentary perspective shared by a remarkably diverse career. His background in law enforcement sharpened his attention to detail and commitment to integrity. His success with Prudential Insurance - including Rookie of the Year recognition and million-dollar producer status - strengthened his client-first approach. He later founded Yacht Connection in Newport Beach, bringing decades of experience navigating sophisticated, high-value transactions in the yachting world.

Together, Coleen and Bill offer something increasingly rare: season perspective without pressure.

They understand that a home may represent far more than real estate. It can be a family's history, a significant financial asset, a lifestyle, a waterfront connection, or the beginning of an entirely new chapter. Their role is to help clients evaluate the possibilities, anticipate the complications, and make confident decisions based on what is right for them.

From Newport Beach, Corona del Mar, and the surrounding coastal communities to second-home and lifestyle opportunities beyond Southern California, Coleen and Bill bring extensive networks, market knowledge, negotiation experience, discretion, and a willingness to do the extra work that exceptional representation requires.

Whether you are considering selling a longtime residence, purchasing a coastal property, making a lifestyle transition, investing, or simply wondering whether now is the right time to make a move, the conversation can begin without obligation or a predetermined outcome.

Because sometimes the most valuable thing a real estate professional can tell you is not how to make a move - but whether you should make one at all.

BEFORE YOU MAKE A MOVE, LET'S TALK.
