Hi, I'm Jen. Finding the right person to help you navigate buying or selling a home is a big decision.

I know buying a home is a big deal, especially in the super competitive East Bay. Expect my unwavering devotion to helping you find your way to your next home, and me to walk you through tough decisions, problem solve, and provide consistent communication.

Selling your home, probably your largest asset, is emotional and can be stressful. I love marketing homes, thinking creatively, and leaving no detail untouched so we can maximize your sale price!

My job is to minimize pain points, educate you, and protect you during the buying or selling process. I will help you develop a strategic plan and back it up with my strong negotiation skills, unparalleled accessibility, and local market expertise.

A little about my background…

I’m the daughter and granddaughter of builders, so it’s no surprise I pursued real estate. Community service is also in my family’s DNA. I started volunteering in high school and have never stopped — my latest volunteer gigs are as Parents Association President and Trustee at my kids’ schools...

Working with Jen Cogen is like having your best friend on your team! As first-time home buyers and non-natives of the Bay Area, the prospect of buying a home has seemed formidable. However, with Jen’s expert knowledge and hands-on guidance, we are better equipped for home-buying success. Through the process, I have personally been impressed with Jen’s sincere desire to serve us as her clients, her genuine concern for my family’s unique needs, her knowledge about the markets, her patient guidance when things don’t work out as planned, and her straightforward and candid nature in her working relationships with other agents and our lender. Jen has an approachable nature and has proven many times that she truly has my family’s best interests at heart. Jen understands how exciting, yet daunting, home buying is and goes the extra mile to get offers noticed. She has been proactive in all aspects of our home-buying education, and I’m grateful she’s on my team!




I'm not the type of person who likes to post a review but our experience with Jen Cogen when we were looking to buy a house definitely deserves a recognition. She’s not like some real estate agents who tries to push you into a buying a house so that they can move on to another client. She listened to us and told us from the beginning that she chose this line of work to help families and it shows. She is very patient and she was there to provide support and guidance in any of our decision. Jen is such an amazing and a wonderful person and I believe that she and John Sefton who also provided his expertise are truly remarkable people. Dudum Real Estate Group is pretty lucky to have these trustworthy and honest people. Thank you so much Jen! You are the best!

Every Realtor® I ever worked with mentioned their "personal touch" and "professionalism..." so much so that I stopped reacting to those words. Jennifer has never mentioned anything like this and instead, she acted that way. She simply put my interest above everyone else's, including her own. She was truly my agent! Sometime it's just little things, like getting hold of the non-responsive agent, other times it's a dedication of working through the holidays, weekends to accommodate the client — me. Jennifer negotiated the hell out of the seller, and in this crazy market I got credit from the seller. What?! A miracle worker!! Even when I'll be buying/selling properties out of Jen's area, she'd still be my first choice, even to manage relationship with other Realtors®.

Jen Cogen has our full recommendation, 110%! We completed a very complicated raw land purchase in Piedmont, requiring thick contingencies and approvals from many government entities and Jen fully protected us during the entire process. Because of her, we always felt covered, well informed and on schedule. Jen used her vast network of professionals to insure we always had the most correct information, and she successfully advised us on difficult decisions as they arose. Jen worked around the clock when the timeline required it, and was understandably flexible as we waffled with our own changes in preferences. Jen always had a smile and a laugh which made the arduous real estate process fun. We will definitely be using Jen for our future sales and purchases.
