The Riley Oakley Group is a mother-and-daughter real estate team working the Cape Cod market out of Osterville, representing buyers and sellers from Barnstable to Falmouth under William Raveis Real Estate. Colleen Riley brings the real estate side; her daughter Sabrina adds a construction background, and the pair say they've built more than 30 years of combined experience together. Across 28 Google reviews dating back to 2022, every one lands at 4 or 5 stars, and the same details keep coming up. Reviewers describe the two coordinating inspections and lining up contractor estimates when issues turned up mid-sale, and more than one seller who had struggled with another broker credits Colleen and Sabrina with turning a stalled listing around — updated photos, virtual staging, and straightforward pricing advice in what one seller called a tough market. First-time buyers get singled out often, several describing being walked through every step of a process that felt overwhelming going in. The relationships tend to go beyond a single transaction. Several clients describe using the team repeatedly across multiple purchases and sales over a period of years — Mashpee to Osterville, Barnstable to Centerville, Sandwich for a daughter's first home — and two industry professionals, a mortgage loan officer and a closing attorney, separately describe repeated, positive dealings with the pair on other people's transactions, the kind of professional word-of-mouth that's harder to manufacture than a client testimonial. One thing worth asking about before getting started: several reviews from 2025 refer to the pair as being with Sotheby's International Realty, while the team's own site and business record name William Raveis Real Estate as their brokerage. Cape agents do move between firms, so it's worth confirming which brokerage currently represents them. For a seller whose listing has sat too long, or a first-time buyer who wants someone to walk them through each step, the record here points to a team built on hands-on coordination and repeat relationships rather than just volume. Confirm the current brokerage and that your town falls in their stated service area before booking a first meeting.
Sabrina and Colleen were amazing. They went above and beyond we would highly recommend them to anyone that’s looking to sell a house on Cape Cod. You get two for the price of one.
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!
I recently worked with Colleen Riley from Sutherby's international Realty. I could not be more pleased with my experience working with Colleen. She was wonderful from the first time we spoke. She was professional knowledgeable, patient and friendly. My phone calls or emails were always returned in a timely manner, putting me at ease throughout the whole real estate process. The sale of my condo went smoothly thanks to Colleen, I highly recommend her
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.
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!
