Mark Miller

Realtor

Hi, I’m Mark Miller—husband, dad, and proud member of the Copley community. My family and I love spending time outdoors, whether it’s hiking in the national park, biking the local trails, kayaking, or fishing. When I’m not out exploring with them, you’ll likely find me on the golf course or connecting with friends and neighbors.

Being involved in the community is important to me, which is why I’m an active member of the Copley Chamber of Commerce. I enjoy supporting local businesses, building relationships, and contributing to the growth of the area I call home.

When it comes to real estate, I focus on helping homeowners list and sell their properties for the best possible price while also working with investors to find strong, profitable opportunities. I also enjoy helping buyers find homes that fit their needs, whether they’re purchasing their first home or relocating. No matter your real estate goals, I believe in effective marketing, honest guidance, and making the process as smooth as possible.

At the end of the day, real estate is about more than just transactions—it’s about helping people make the right move at the right time. If you’re thinking about selling, investing, or buying, let’s connect—I’d love to help.

Realtor

I’m Katie Middendorf — Associate Broker, founding partner of Carolyn Riley Property Management (CRPM) and Assoc Broker at C21 Carolyn Riley Realty.  I’m a real estate strategist with a passion for restoring property performance and creating stability for owners and communities.

My journey began in sales and marketing, but I found my true professional calling through managing my own investment properties starting in 2007. By 2014, I transitioned full time into real estate and earned my broker’s license in 2018. Today, in partnership with Patrick Riley, I lead CRPM’s daily operations, overseeing a driven team of 12 women managing 700+ rental units and several associations across Northeast Ohio, complimented by partnering with Mark Miller to spearhead acquisitions and profitable dispositions through the C21 Brand.

My core expertise is helping owners navigate distressed and underperforming assets — identifying issues, creating customized strategies, and turning properties into reliable, cash-flowing investments. As part of Century21 Carolyn Riley Realty’s Signature Group, I also consult on investor acquisitions, portfolio growth, and retail residential sales.

Outside of work, I’m a community advocate, mom of two, lover of dogs, and wife to a general contractor who (unintentionally) sparked my love for this industry. Whether I’m supporting school programs, helping at local shelters, or contributing through the Copley and Fairlawn Chambers, I’m all in on bettering the places we live and the people we serve.

Realtor

I’m Justin Decker, a real estate agent who’s passionate about helping people make smart moves — whether that means finding the perfect home or locking in a strong investment. I love working with buyers who want great deals on great houses, and I take pride in negotiating hard, protecting my clients’ interests, and guiding them with honesty and clarity every step of the way.

Over the past year, I’ve helped buyers and sellers successfully close on 30+ properties, giving me hands-on experience across a wide range of neighborhoods, price points, and deal types. That experience has strengthened my ability to navigate complex situations, identify value quickly, and create smooth, strategic paths to the closing table.

I spend much of my time working closely with investors throughout Northeast Ohio, helping them identify high-value opportunities that strengthen their portfolios. From analyzing returns to navigating inspections and negotiations, I’m committed to making every transaction efficient, informed, and successful. I also love helping homebuyers find a place they’re excited to call home.

My goal is simple: deliver results, earn trust, and make sure my clients feel supported from the first conversation to the closing table. If you’re ready to buy, sell, or invest, I’d love to help you take the next step. Let’s talk about your goals and make your move a smart one.
