You don’t need to be ready to move before talking to a REALTOR®. Sometimes you just need someone who will answer your questions honestly and help you figure out what is actually possible. 🏡
Hi, I’m Sidney O’Brien!
I’m a REALTOR® with Lamacchia Realty, licensed in both Massachusetts and New Hampshire. I grew up in Billerica, spending half of my childhood in Pinehurst and the other half in Lakeside, and I now call Woburn home.
Real estate is not my only background. I also work full time as a healthcare operations manager and am currently earning my doctorate. Helping people, solving problems, and keeping things organized during stressful situations are all part of who I am, and those skills naturally carry into the way I support my real estate clients.
I understand that buying or selling a home can feel intimidating, especially when you have no idea where to begin. Maybe you are wondering whether you can afford to buy. Maybe your current home no longer fits your life. Maybe you are relocating, searching for a rental, or simply trying to understand the market.
Whatever stage you are in, you can reach out to me.
You do not need perfect credit.
You do not need to have every detail figured out.
You do not need to be buying or selling tomorrow.
We can start with a simple, no-pressure conversation about your situation, your questions, and what your next steps could look like.
I am still building my real estate business, and I’m doing it by focusing on what matters most to me: genuine connections, honest guidance, and making sure my clients feel supported instead of pressured.
If you know someone who could use a hardworking, approachable, and down-to-earth REALTOR® in their corner, I would be so grateful if you shared my information or connected us.
Whether your move is happening next month, next year, or is still only an idea, I’m here when you’re ready. 🤍
