About Jennifer (Jen)

Meet Jen Mummau — Realtor®, Advocate, and Guide for Life’s Big Moves After more than 20+ years in healthcare, I made a bold leap into real estate many years ago—a decision driven by my passion for helping people through life’s biggest transitions. I bring the same heart, attentiveness, and empathy that I gave to my patients into every client relationship I build today. I’m not your average Realtor®. I don't just open doors; I help you navigate the emotional and financial complexities of buying or selling a home. My clients often become close friends because I treat every transaction like it’s personal—because it is! Whether you're downsizing after decades, investing for the first time, or buying your dream home, I’m with you every step of the way, guiding with a calm presence, strategic mindset, and a whole lot of heart. My brand is rooted in authenticity, trust, and a calm, confident approach that keeps clients grounded during big decisions. I don’t do fluff or pressure—I do real conversations, real solutions, and real results. I’ve built my business by listening more than talking, showing up consistently, and prioritizing people over transactions. The numbers have followed—doubling each year since I began. What makes me different? I understand the life part behind the real estate. I see beyond the contract and the closing table to what really matters: feeling seen, heard, and supported. This work is personal to me—and when we work together, your goals become my mission. Let’s find what home means for you! Visit my website at Jenmummau.myrealtyonegroup.com

BEST REALTOR EVER

Jen was amazing at communication. She kept me up to date every step of the way through selling my house! She gave me very wise council when the offers came in. Jen went above and beyond for me. I was not physically allowed to pick up more than 10 pounds and she helped wrap up some last minute things for the house to be ready to be sold! She negotiated with the buyers realtor efficiently and firmly to get me the best price on my home! I would definitely recommend Jen to any way buying or selling their home! Thank you Jen

Jen has been a remarkable agent all around.

We finally did it! We sold our home of nearly twenty years and bought our second family home. We can thank our agent Jennifer Mummau, for her guidance and all of her support. She provided us with a wealth of guidance in the process. She was very flexible and knowledgeable. Jen showed her flexibility with our tight work schedules. She was very considerate of our time and always professional. When it came to decision making, she informed us of every step and often walked us through the entire process assuring us that we will make it happen. The sale of our home for a new fresh start. Jen made it happen! It has been a pleasure to work with her. I would highly recommend her to anyone that is looking to buy or sell a home.

We highly recommend Jen!

We reached out to Jen to help us through a long distance move to PA. She stepped up to the challenge and was instrumental in making sure everything continued through the process successfully. Jen is a true professional and thinks outside the box in every aspect. We're very happy with our experience with Jen.

She's the agent you need in your corner.

Jennifer is beyond amazing! She helped us through every step of the home buying process. There are not enough words to explain how truly grateful we are to have had her through the beginning of the process and even beyond us closing on our home. We closed months ago and she's still assisting us. She's fantastic and I can't recommend her enough!
