About The Collective

Meet Our Agents

Amber Purty

Designated Broker, Owner

Born and raised in Maine, I’ve always had a deep appreciation for the unique character and lifestyle our state offers. I began my real estate career in 2014 with a national brokerage, later joined a boutique local agency, and eventually launched my own firm based in Cumberland Maine.

My team and I specialize in helping clients buy and sell primary residences, investment properties, and second homes across the southern and central areas of the state. We offer more than just a traditional brokerage—we’re hands-on with project oversight, design guidance, remodel support, and property management. All of our agents, including myself, are personally real estate investors and homeowners, giving us first-hand insight into the process.

I’m a proud University of Maine graduate, a mom to twin daughters Everly and Reese, wife to my loving husband Anthony, and dog mom to our rescue pitbulls, Booboo and Buster. When I’m not helping clients or managing projects, you’ll find me enjoying everything this beautiful state has to offer from paddle boarding and swimming in MoosePond, to building sand castles and searching for shells on the coast, to snowboarding and relaxing around the fire in the winter months.

At The Collective Real Estate Co. our clients are never a number, no transaction ever follows a template, and your real estate journey is personalized to you every step of the way. We take pride in helping each client reach their goal, in the most efficient and successful way possible as your advocate, your expert, and your partner from day one.

Nicole Mueller

Broker

Hi, I’m Nicole Mueller.

I’m a licensed real estate broker with The Collective Real Estate Co, proudly serving the Greater Portland area and beyond. I’ve been helping clients buy, sell, and invest in Maine real estate since 2014—but my approach has always been the same: client-first, always.

As a longtime Falmouth resident and mom of three young kids, I know how important it is to find not just a house, but a home that fits your lifestyle, your goals, and your future. Whether you’re navigating a first-time purchase, selling a home full of memories, or exploring an investment opportunity, I’ll be there every step of the way with honest advice, local expertise, and steady support.

Alongside helping clients with real estate, I also manage a portfolio of short-term rental properties. This gives me firsthand insight into what makes a vacation home a smart investment—and how to maximize its potential.

Real estate is more than a transaction—it’s a transition. I’m here to make sure yours is a successful one.

Let’s connect.

Whether you’re ready to make a move or just starting to explore your options, I’d love to hear from you.

Ryan McQuaid

Agent

With deep roots in Southern Maine and a passion for real estate, property management, and customer satisfaction, I strive to bring local expertise and a commitment to excellence in real estate property management. Specializing in residential and multi-family property oversight, I look to partner with homeowners and investors to identify assets, facilitate the dream of home ownership, protect investments, maximize rental income, and maintain long-term tenant satisfaction.

Whether you’re a first-time landlord or a seasoned investor, my hands-on approach ensures your property is managed with integrity, transparency, and attention to detail. From tenant placement and lease enforcement to maintenance coordination and financial reporting, I delivers full-service solutions tailored to the unique demands of the Southern Maine market.

Known for my responsiveness, reliability, and deep knowledge of local housing trends, I aim to be a trusted resource for anyone looking to simplify and strengthen their real estate investment experience.
