About The Riley Oakley Group

"Sabrina and Colleen helped my fiance and I find our little slice of Cape Cod. They are so knowledgeable about the buying and selling process and the cape market specifically. As first time homebuyers, they made the process much easier, walking us through each and every step and deadline. We are so grateful for their help in this otherwise daunting process. 10/10 recommend"

"We struggled to sell our home for a while with another broker, but everything changed when we switched to Colleen & Sabrina.

They improved our photos, added virtual staging, and gave us straightforward advice about pricing in a tough market. We immediately saw more interest.

Super responsive and easy to work with - honestly wish we had started with them. So grateful they got our home sold. Definitely recommend!

"Colleen, you did a wonderful job with listing our condo. Your professionalism. Everything was wonderful. You'll be very successful. I'm sure forever take care. Thank you very much for everything. It was a great experience."
Thomas Roycroft

"We couldn't be happier with our experience working with Coleen and Sabrina to buy our home on Cape Cod. This mother-daughter team is the real deal - deeply rooted in the Cape, genuinely knowledgeable, and an absolute pleasure to work with from start to finish.

Their command of the local market is exceptional. They knew the neighborhoods, the pricing trends, and the regulations around buying on the Cape. They were always available when we had questions, and we never felt rushed or left in the dark. Their knowledge of construction was also invaluable - they could walk through a property and quickly assess what was solid, what needed work, and what the real costs might look like. That kind of practical insight is rare and made a huge difference in how we evaluated each home.

Beyond their expertise, both Coleen and Sabrina were warm, patient, and genuinely fun to spend time with. House hunting can be stressful, but they made the process feel manageable and even enjoyable. They negotiated skillfully on our behalf and were always looking out for our best interests.

If you're buying on Cape Cod, look no further. This team knows the market inside and out, and they will take care of you every step of the way. Highly recommend!

Sheryl Walsh

"I met Colleen in 2014 when I was purchasing a home and she was representing the seller. I was very impressed by her professionalism! When it came to selling my home in 2020, Colleen was the first person I thought of. Once listed, the home had a contact within a week with an above asking price. I have since purchased and sold a property in Falmouth, and purchased another property in Mashpee. Once again, Colleen was by my side. She checked in with me daily to answer questions and make sure the transactions were as seamless as possible. When it comes to selling your home (or searching for the perfect home), Colleen is trustworthy, professional, hardworking, goes the extra mile, and is always pleasant to work with."

"I have known Colleen personally for several years! When the opportunity arose that we had to sell my parents beloved estate, I went to Colleen and spoke with her directly. She had to meet my brothers and I knew she would be the right person! to represent us in selling our parents estate. She worked hard w/ 4 Open Houses in 3 weeks, when the perfect buyer came along! The Ariel's photos were amazing, and she incorporated in the video the heart of Centerville Village. Colleen Along with her daughter Sabrina really showcased our home well. She was very easy to work with, from the start though the closing! If you are looking for a dedicated real estate professional, she is top of her game, as full service top Cape Realtor, she is very knowledgeable about the many desirable villages in the town of Barnstable. Moreover, at the heart of it, she cares about each of her clients, and building relationships, which in my opinion is why she is so very good at what she does! My brothers & I are so happy with the high level - high touch service we received from Colleen! In fact if I was looking to buy a property on Cape Cod, I would call up Colleen in a heart beat, knowing her strong ethics, dedication and expertise, she is 2nd to none in the real estate business!"
Elizabeth MacAleese

"Colleen was awesome to work with from start to finish. It the first time I was making a home purchase on my own and I wasn't that excited about the process. That was until Colleen gave me such hope and encouragement to keep looking. She would send me listings regularly and pushed me to go see the houses in person. I ended up with such a gem in the cutest neighborhood and she was there every step of the way through the negotiating and closing process. I completely trusted her to give me sound advice and it all paid off. Couldn't be happier with the outcome and I have Colleen to thank for how smoothly everything went. Her experience and knowledge of the Cape housing market is truly remarkable."
Stephanie Sharlet

"Working with Colleen on selling our house, was an absolute pleasure. She provided us with outstanding market comparisons and the photos that were done to showcase the house for sale, were top notch. Her kind and caring nature made an emotional time for us, more bearable. I would highly recommend working with Colleen and Sabrina!!!"
Jill

"Colleen & Sabrina are quite the professional Real Estate duo!
Collen brings the many years of her real estate experiences to the team and Sabrina brings a creative keen eye from her construction background. Both are hardworking, diligent, very detailed and highly professional in their approach to the real estate transaction.

This will be our fourth real estate listing with them and each one has been unique with different issues. They have a stable of industry contacts who can respond to the various issues that come up during the process.

You cannot go wrong! We highly recommend Colleen and Sabrina in your real estate pursuits.

As we had to do mail away closing and lived across the country, they helped coordinate and arrange everything including touring as many houses as possible during the one day we had to visit.
