About John Carroll

"TEAM HARMON/CARROLL named the #1 Brokers for Cumberland & York Counties for The Maine Real Estate Network in 2014”


Thank you for considering Team Harmon for all of your Real Estate needs The members of Team Harmon are dedicated to providing the best service possible for every client we represent We are fully committed to the needs of you your family or your business We have sold homes across much of southern and central Maine from York to Newcastle and Portland to Denmark

As your representative Team Harmon will work hard to negotiate the sale of your property or purchase of your new home or investment property at the best possible price and terms and strive to make all stages of the selling & buying process as smooth and stress-free as possible

Team Harmon was formed in 1996 by John C Harmon Sr and John Harmon II within Agency 1 Real Estate Agency 1 Real Estate was founded in 1972 by Rocco and Marcia Risbara and became affiliated with ERA Franchise systems in 1979 John C Harmon Sr had been affiliated with Agency 1 Real Estate since September 1979 In 1993 he purchased the company which he successfully grew into a Top 25 ERA company worldwide and one of the top selling real estate companies in Southern Maine Agency 1 was awarded with Customer Satisfaction awards for 10 plus consecutive years

In June 1996 John Harmon II joined Agency 1 Real Estate He and his father began Team Harmon where they worked together until 2002 when John Harmon II took over the reins of both Team Harmon and Agency 1 Real Estate John Harmon II continued on as designated broker and owner of the company until 2010

In December 2010 Agency 1 Real Estate merged with and became The Maine Real Estate Network The Maine Real Estate Network was founded in 2007 by Loni Graiver and grew rapidly over the next three years attracting many top producing agents it became a significant force in the Southern Maine real estate market by 2010 The merger between The Maine Real Estate Network and Agency 1 Real Estate has created what is now the largest non-franchised real estate agency in the State of Maine

Coming from a background of 40 years in the Southern Maine real estate industry we are proud to say that The Maine Real Estate Network is the Largest Real Estate Company in the State and still remains a family owned and independently run company with over 450+ agents and support staff and 22 offices conveniently located in Cumberland York Oxford Androscoggin & Knox Counties We strive to make each of our offices a “Home Town” agency with the top service and experience you would expect from a national or worldwide company

Team Harmon has the tools you need
All of our clients are unique That's why we give every client their very own private Web page where they can track properties they're interested in see scheduled showings and appointments and view special materials we have prepared just for them And that's why all our clients have access to the most complete and up-to-date source of online property listings on the Internet

Understand the process
Buying real estate is a complex matter and can be especially confusing for the first-time homebuyer Do yourself a favor and learn as much about the process as you can before you begin There are plenty of resources on the Internet and most real estate offices will have pamphlets to explain things in plain language You may also be able to research the real estate process by attending community-sponsored classes or you can take a look at books like Home Buying For Dummies by Eric Tyson and Ray Brown (IDG Books Worldwide Inc )

Use a REALTOR(R)
As a buyer it usually costs nothing to hire a real estate professional to help you find and purchase a home--your Realtor will likely get a portion of the commission the seller pays to his Realtor When choosing an agent get referrals from friends relatives and co-workers and then interview as many agents as possible Pick an agent that works in the neighborhoods you're interested in Listen to your agent but make your own

If you need to reach active real estate agents in Cumberland County, Maine, this list was built for you. Mortgage lenders looking to grow referral partnerships, title companies expanding their agent network, PropTech platforms launching in New England, and continuing education providers targeting license renewal cycles are among the most frequent buyers. Insurance professionals, recruiters building agent pipelines, and B2B marketers with agent-specific offers round out the typical customer profile.

When you buy a Cumberland County real estate agent email list, you are investing in direct access to verified, licensed professionals — not a scraped directory of outdated contacts. This list gives you {{AGENT_COUNT}} actively licensed agents with confirmed email addresses, plus {{CELL_COUNT}} agents who also have verified cell phone numbers on file. Whether you are launching a cold email sequence through a platform like Zap Contact (zapcontact.com) or building a multi-channel outreach campaign, these are the contacts that actually move the needle.

Why Buy a Cumberland County Real Estate Agent Email List From Dr Bill

Data quality is not an afterthought here — it is the product. Every contact is sourced directly from the Maine state real estate licensing board, meaning you are only reaching agents who are currently licensed and legally practicing. New emails are added weekly, the list is cleaned monthly, and the entire database is fully refreshed twice per year. That discipline produces a 96% deliverability guarantee that cheap list vendors simply cannot match.

Generic list brokers sell you whatever they have sitting in a flat file. Dr Bill has been doing this since 2005 and has sold over 31,000 lists across the country. That track record exists because the methodology is rigorous and the data holds up when clients actually use it. When your campaign goes out, you are not burning sender reputation on dead addresses.

How to Use This Cumberland County Agent List

Cold email is the most common use case, and this list is formatted for immediate upload into platforms like Zap Contact and other modern cold-email tools. From there you can build automated sequences, track opens and replies, and follow up with direct mail or phone outreach using the included cell numbers. LinkedIn matching is another powerful tactic — upload the emails as a custom audience and run targeted ads alongside your email sequence.

Segmenting by broker versus sales agent lets you tailor your message by decision-making authority. A broker needs to hear a different pitch than an independent agent building their own book of business. Having that distinction inside the data makes your campaigns sharper and your conversion rates higher.

Why Cumberland County, Maine Agent Data Matters

Cumberland County covers Portland, South Portland, Scarborough, Westbrook, Falmouth, Cape Elizabeth, and Gorham — a concentrated pocket of real estate activity that rewards precise targeting. With {{AGENT_COUNT}} licensed agents operating across this geography, there is real volume here, and no other vendor offers segmentation down to the zip code level within the county.

Statewide blasts waste spend on agents in markets that are irrelevant to your offer. Targeting Cumberland County specifically means your message lands with agents who are actually active in the communities and price points your product or service serves, making every send more relevant and every response more valuable.
