About Diana.
Built on trust, backed by results — that's the promise I bring to every client I serve.
With over 10 years of experience in real estate and a deep background in construction and investment properties, I bring a level of insight to the table that goes far beyond the average agent. I understand how homes are built, what to look for beneath the surface, and how to evaluate a property not just as a home — but as a smart financial decision.
Real estate isn't just my career — it's my passion. I genuinely love what I do, and more importantly, I love the people I get to do it for. Whether you're buying your very first home, growing your investment portfolio, or navigating a major life transition, I'm here to walk alongside you every step of the way. I believe real estate is an act of service, and I take that responsibility seriously.
Communication is at the heart of everything I do. I know how important it is to feel heard, informed, and confident throughout the process — especially during one of the biggest decisions of your life. I'm a committed team player who works collaboratively with clients, lenders, inspectors, and fellow agents to make sure every transaction moves forward smoothly and on your timeline.
Serving buyers and sellers throughout Southeast Michigan, including Oakland, Wayne, Macomb, Livingston, Washtenaw, and Genesee counties.
When you work with me, you're not just getting an agent — you're getting a dedicated advocate who is skilled, knowledgeable, and fully committed to your success. Your real estate journey is personal, and I'm honored to be a part of it.

What clients say about the MARK Z team.
Real clients, real closings — pulled straight from our public review profiles.
“Top notch real estate company! Professional and knowledgeable of the market. They sold my house in 2 weeks, and we closed a week early!”
“Steve did an amazing job helping us sell our condo. From being our ‘boots on the ground’ (we’re out of state) to making sure everything was taken care of.”
“Edgar is truly the best! He just helped me sell the same home he helped me buy 4 years ago — and got my offer accepted on the new one.”
“As first-time home buyers, the process was more than smooth. Always responsive, patient, knowledgeable, and reliable.”
“Zach did so well on the listing of my first property I had to run it back on the second! Communicative through the entire process.”
“Very impressed with the entire Z Realty team! Extremely professional and helpful since we live out of town. Highly recommend.”
