My Team

I feel fortunate to have found an A-team of hard workers with complementary skill sets: Each person’s contribution allows us to get better every day, together. We’re a boutique agency that brings diverse talent to every project. My team includes a graphic designer who used to own an art gallery, a project coordinator with deep analytical experience who’s also been in Wendy’s television ads, a marketer who grew a major craft brewery’s social media following by 10,000%, and an office administrator who studied vocal performance and may as well have a master’s degree in multitasking. Learn more about each of them below.

Born in Michigan’s Upper Peninsula, she loved drawing floor plans and painting homes from a young age. She was class clown in high school and studied Urban Planning at Michigan State University.

She is active in Chicago’s art scene and enjoys live music, good eats, and secondhand gems.

Hannah Clark, Jason O'Beirne Realty Office Administrator

Hannah Clark

Hannah has 7 years of experience working in administrative, operations, and client services roles at law and optometrist offices and salons. She’s fantastic at both holding things together and keeping us all moving forward in her role as Office Administrator and Executive Assistant. Hannah makes the rest of us jealous with her insider knowledge of the city’s best dining establishments and even has her name on a custom set of chopsticks at her favorite sushi spot. Hannah manages to be both professional and fun at the same time—she’s the perfect addition to our team. And she just got her realtor’s license!


Sarah Aldrich

As Digital Marketing Manager, Sarah brings a decade of experience to the team. She began working in the industry while studying Professional Writing at Michigan State University, interning for the university, Martha Stewart, and National Geographic. Sarah started her career as the first marketing employee at Founders Brewing in Grand Rapids, Michigan, leading the brand’s growth for 5 years. She claims that becoming a beer snob at the tender age of 22 is both a blessing and a curse. Sarah then moved to Vietnam, where she started a freelance writing and marketing consulting business. She has recently returned to Grand Rapids, happily reunited with her family and her dog, Tessa.



“Jason and his team provide a level of service that is extremely difficult to find in the industry—better than any others I have worked with during my 15 years (and $250 million+ in residential sales) in the business. He works tirelessly for his clients, is very responsive and well organized, and always goes the extra mile to make sure that his clients achieve their goals. In addition, Jason knows the Chicago market and pricing dynamics better than just about anyone that I have worked with. He is a great resource and someone that I look forward to working with in the future.”

William, Developer

“We noticed that you took over the listing across the street. Once your name was on the sign, we had no doubt in our mind that it would sell!! Thanks for everything you do for the neighborhood. It is much appreciated!!”

Dani and Charlie, Past Buyers

“Choosing the right agent for your particular needs is one of the most important steps in the real estate process. Words cannot describe how lucky I am to work with Jason. He is a top-performing agent, knowledgeable, professional, well organized, very responsive, and has a great personality, too.”

Marcin, Builder

“I’ve been asked a few times to provide testimonials for my peers. Jason is one of the few I’d jump to do. When I work with Jason I know the deal will be handled ethically. That’s saying a lot in our field. Real estate isn’t that transparent and I think Jason brings trust to the closing table. His communication skills are exceptional! Any broker will tell you that it’s a key ingredient to a successful deal. Jason is one of the good guys!”

Alley, Agent

“Jason and his team (Mike in our case) were fantastic throughout the process! They were available/flexible and knowledgeable both about the area and the home-buying process… Highly recommend!”

Raju and Lindsey, Buyers

We really enjoyed working with you, and would recommend you to our friends and family without hesitance. None of our friends or coworkers in the city had an agent they could recommend to us, which says a lot. In an industry where the consumer has a lot of information at their fingertips and can navigate plenty on their own, you managed to provide tremendous value. Heartfelt thanks and we look forward to working with you again in the future!
