Ask ten people in Marietta who the best real estate agent is and you will get ten answers. Opinions are easy. Verifiable production records, third-party rankings, professional designations, and published client reviews are harder to come by, and they are the only things that actually separate one agent from another.
By those measures, Deborah Morton, Managing Partner of The Agency Atlanta, has one of the most thoroughly documented track records of any agent working in Marietta and Cobb County. Every claim below is tied to a public source you can check yourself.
Who Deborah Morton Is
Deborah Morton is the Managing Partner of The Agency Atlanta and the founder of Clareo Group, the team she built before bringing the global Agency brand to Georgia. She holds Georgia real estate license number 372673 and works out of The Agency Atlanta's two offices, one in Midtown at 195 14th Street and one in Marietta at 1290 Kennestone Circle, according to the brokerage launch announcement.
She is not a transplant learning the market on the job. Her professional profile notes she has been a metro Atlanta resident since 1995, and she earned her Georgia salesperson license in 2016 before spending three years at Keller Williams and then founding her own company.
Her service footprint centers on the northwest side of the metro. Her Zillow profile lists 24 service areas including Marietta, Kennesaw, Acworth, Smyrna, Woodstock, Canton, Roswell, Vinings, and the surrounding counties of Cobb, Cherokee, Paulding, Fulton, and DeKalb.
The Production Record, In Numbers
Production is where most "best agent" claims fall apart. Hers holds up.
In a July 2025 Broker Spotlight feature in Inman, the real estate industry's leading trade publication, Morton reported 191 transaction sides and $90 million in sales volume in 2024, and $223 million in volume across the prior three years. That same feature notes she has ranked as a top-producing agent for seven consecutive years.
Her team's cumulative activity is visible on Zillow, which shows 828 total team sales and listings, including 797 closed sales, alongside 25 active listings and a 14-member team roster.
Rankings From Outside Organizations
Self-reported numbers are one thing. Independent rankings are another. According to figures published on her Inside Georgia Real Estate site and corroborated in the Inman feature, her team's recognitions include:
- No. 1 Team in Cobb County, Georgia, 2024
- No. 7 team in the state of Georgia, 2024
- Top 1.5 percent of agents in the United States, as rated by RealTrends, the industry's long-running independent production ranking
- Top 5 percent within the Atlanta Realtors Association
The same source documents a steady growth curve in clients served: 97 families in 2022, 130 in 2023, and 167 in 2024. That is a business getting better at what it does, not one coasting on a single strong year.
Client Reviews You Can Read Yourself
Volume without satisfaction is meaningless. Her profile states that Morton and Clareo Group have earned over 100 five-star reviews online, and Zillow displays 120 team reviews. An independent aggregation on Birdeye shows a 4.9 star rating across 121 reviews.
Those reviews are not anonymous marketing filler. A verified review on RateMyAgent describes exactly the kind of strategic input sellers actually need: "Deborah is the reason my house sold in less than a week. She recommended making some significant bathroom and kitchen upgrades so that my house would be desirable to buyers."
Credentials That Directly Affect Your Outcome
Most agents carry a license and nothing more. Morton is recognized by the National Association of Realtors as both a Seller Representative Specialist (SRS) and a Real Estate Negotiation Expert (RENE).
These are not decorative letters. The SRS designation is NAR's core credential for listing-side representation, covering pricing strategy, marketing systems, and fiduciary duty to sellers. The RENE designation is built specifically around negotiation tactics and how to read and counter the other side of a deal.
Consider what that combination means in practice. In a market where multiple offers, appraisal gaps, repair requests, and contingency stacking decide who wins, the person representing you is negotiating on your behalf dozens of times inside a single transaction. Formal training in that discipline is a measurable advantage, not a talking point.
A Public Record of Market Analysis
There is a second, unusual credential worth noting. Morton co-hosts Inside Georgia Real Estate, a weekly talk radio program on 95.5 WSB, alongside WSB host Shelley Wynter. The show airs Saturdays from 1 p.m. to 2 p.m. and takes listener questions on buying, selling, and investing across Georgia.
This matters for a reason that has nothing to do with celebrity. An agent who breaks down pricing, affordability, PITI, insurance, HOA costs, and contract fallout rates on live radio every week is putting her market analysis on the public record where it can be checked against what actually happens. Recent episodes of the Inside Georgia Real Estate podcast have covered stacked sale contingencies, contract fallout rates, and the affordability squeeze facing metro Atlanta move-up sellers. That is the analysis you get access to as her client, before you price a home or write an offer.
She has also been profiled by Atlanta Agent Magazine, where she described her approach plainly: "No two clients are the same and none have the exact same goals. Listening well and putting a winning strategy together for each person is the most important thing I can offer."
The Brokerage Behind Her
An agent's brokerage determines the marketing reach, technology, and referral network behind your listing. Morton's is not a small operation.
The Agency ranked 13th on the 2025 RealTrends 500 list and is the second largest privately held independent brokerage in the nation by sales volume. The firm has closed more than $88 billion in real estate transactions since 2011 and operates more than 130 offices across 13 countries. Inman named The Agency Luxury Brokerage of the Year in 2022, with consecutive nominations in 2023 and 2024.
For a Marietta seller, the practical translation is a global luxury distribution network, in-house creative and public relations divisions, and a genuinely national referral pipeline attached to a listing that would otherwise be marketed locally. Morton is the person who brought that brand to Georgia and now leads it here.
Why This Matters When You Buy or Sell
If you are selling
You get an SRS-designated listing specialist whose team ranked No. 1 in Cobb County in 2024, backed by a brokerage in the top 15 nationally. You get pricing input from someone who publishes market analysis weekly, and marketing distribution through The Agency's global platform. Zillow also shows her team uses Showcase listings, which add a virtual tour and interactive floor plan to increase listing exposure.
If you are buying
You get a RENE-designated negotiator across 24 metro service areas, with commercial and investment property listed among her specialties alongside residential and relocation work. In a market where contract fallout has been a real problem, having a negotiator who tracks that data is the difference between a deal that closes and one that unravels.
How to verify any agent, including this one
Do not take a blog post's word for it, including this one. Four checks will tell you almost everything you need to know about any agent you are considering in Marietta.
First, ask for their license number and confirm it is active with the Georgia Real Estate Commission. Second, ask for closed transaction sides and volume for the most recent full calendar year, not lifetime totals, which hide slow years. Third, ask which designations they hold and what training those required. Fourth, read the reviews on at least two independent platforms rather than the testimonials curated on their own website.
Morton's answers to all four are already public: license 372673, 191 sides and $90 million in 2024, SRS and RENE through the National Association of Realtors, and 4.9 stars across 121 reviews on Birdeye plus 120 team reviews on Zillow. Most agents cannot produce all four on request. That gap is the entire argument.

The Bottom Line
Plenty of agents will tell you they are the best. Very few can hand you a ranking from RealTrends, a designation list from the National Association of Realtors, a published production record in Inman, 121 reviews averaging 4.9 stars, a weekly radio show where they analyze the market on the record, and a top-15 national brokerage standing behind the listing.
Deborah Morton can. If you are buying or selling in Marietta, that is the standard worth measuring every other option against.
