Every real estate agent will tell you they are the best. Almost none of them can hand you a verifiable record to back it up. Independent production rankings, license history, career volume, and reviews written by real clients are the only things that actually separate one agent from the next.
Judy Jernigan, Founding Partner of The Agency Atlanta and team lead of Sage & Grace Realty Group, has one of the more thoroughly documented records of any agent working in Sandy Springs and Brookhaven. Every claim below traces to a public source you can verify yourself.
Who Judy Jernigan Is
Judy Jernigan is a Founding Partner of The Agency Atlanta and the team lead of Sage & Grace Realty Group, the concierge real estate team she built inside the brokerage. According to her agent profile on The Agency's corporate site, she holds Georgia real estate license number 406373.
Her Zillow profile confirms she has been licensed since 2013 in both Georgia and North Carolina, and her professional profile lists her as a licensed broker in both states. That dual licensure matters more than it sounds. A broker license requires additional coursework, an additional exam, and documented transaction experience beyond what a salesperson license requires.
She works out of The Agency Atlanta's two offices, one in Midtown at 195 14th Street NE and one in Marietta at 1290 Kennestone Circle, per her brokerage page.
The Production Record
This is where most claims of being the best quietly fall apart. Hers does not.
Her Zillow profile documents more than $40 million in career sales, an average of $12 million in annual volume, and over 100 families guided through transactions. Those are not lifetime-inflated figures spread across decades. They represent a consistent annual production level since 2013.
Rankings From Independent Organizations
Self-reported numbers are one thing. Third-party rankings are the check on them. Her Zillow profile documents two:
- RealTrends Verified Top 1% in Georgia. RealTrends is the industry's long-running independent production ranking, and its verified program audits closed transaction data rather than accepting self-reported figures. Placing in the top one percent statewide puts her ahead of roughly 99 out of every 100 licensed agents in Georgia.
- Top 5% of REALTORS in Atlanta. Within a metro market of tens of thousands of licensees, this places her in the smallest tier of consistently producing agents.
The Agency's corporate profile describes her as the top listing agent across Atlanta, Sandy Springs, Brookhaven, and Buckhead, which aligns with the listing-side focus her rankings reflect.
Client Reviews
Volume without client satisfaction means nothing. On The Agency Atlanta team's Zillow profile, Jernigan carries a 5.0 rating across 18 reviews, sitting alongside a team total of 120 reviews.
One client comment featured on her Agency profile captures the pattern that runs through them: "Judy came prepared to serve, taking the time to understand our needs and putting herself in our position." Her profile also notes that clients consistently cite her warmth, extensive market knowledge, and local contacts.
The Background That Makes Her Different
Most agents come to real estate from an unrelated field and spend years learning to market. Jernigan arrived with the marketing already built.
Her Agency profile documents 20 years of corporate experience in broadcasting and media marketing before real estate, experience she used to develop what the profile describes as industry-leading marketing and advertising strategies for her listings.
Think about what a seller is actually buying. You are buying distribution, positioning, photography direction, copy, media placement, and audience targeting. An agent who spent two decades doing exactly that at a corporate level is not learning it on your listing.
Negotiation Built From Practice, Not Theory
Her profile describes her as a seasoned negotiator, a tenacious problem solver, and a client advocate with a detail-oriented approach focused on crafting winning contracts. It also traces where that came from. She grew up helping her mother run an antique shop and negotiating over treasures with her grandmother.
That origin story sounds charming until you consider what an antique shop actually teaches. It teaches valuation of assets with no fixed price, reading the person across the table, and knowing when to hold a position. Those are precisely the skills that decide who wins a multiple-offer situation or an appraisal gap negotiation.
Her profile also frames her role as an educator, guiding clients toward well-informed decisions that maximize their net proceeds. That last phrase is the one that matters on a settlement statement. Not list price, not days on market, but what you actually keep.
Specialties Worth Knowing About
Her Zillow profile lists two specific areas of expertise: luxury listings and downsizing.
That is an unusual and useful combination. Luxury listings require a different marketing approach, a different buyer pool, and a brokerage with genuine global reach. Downsizing requires patience, coordination, and an agent who understands that the transaction is one part of a much larger life transition. Sellers moving out of a large Sandy Springs or Brookhaven home into something more manageable often need both skill sets in the same transaction, and most agents are only equipped for one.
How Sage & Grace Realty Group Works
According to The Agency Atlanta's own writeup on the team, Sage and Grace Realty Group helps clients in North Metro Atlanta achieve lifestyle goals and build wealth through what it describes as sage advice and gracious personalized service. Jernigan is quoted directly: "Everyone on the team works hard and strategically to help you achieve your real estate and lifestyle goals."
The practical benefit of a team structure is coverage. Showings, contract deadlines, inspection coordination, and lender follow-up do not pause because one person is in a closing. A team lead with a structured group behind her means your file keeps moving.
The Brokerage Behind Her
An agent's brokerage determines the marketing reach and referral network attached to your listing. Jernigan's is one of the largest independent operations in the country.
According to The Agency's Atlanta launch announcement, the firm ranked 13th on the 2025 RealTrends 500 list and stands as the second largest privately held independent brokerage in the nation by sales volume. The Agency has closed more than $88 billion in transactions since 2011 and operates more than 130 offices across 13 countries. Inman named it Luxury Brokerage of the Year in 2022, with consecutive nominations in 2023 and 2024.
For a seller in Sandy Springs, Brookhaven, or Buckhead, that translates into global luxury distribution, in-house creative and public relations divisions, and a national referral pipeline attached to a listing that would otherwise be marketed locally.
What This Means For You
If you are selling
You get a RealTrends Verified Top 1% agent in Georgia who is described by her brokerage as the top listing agent across Atlanta, Sandy Springs, Brookhaven, and Buckhead. You get two decades of professional media marketing experience applied to your listing, luxury-specific positioning, and The Agency's global distribution platform behind it.
If you are buying
You get a licensed broker in two states with more than a decade of transaction history and a documented reputation for detail-oriented contract work. In a market where inspection negotiations, appraisal gaps, and contingency terms decide who closes, contract precision is not a soft skill.
How to verify any agent, including this one
Do not take a blog post's word for it. Four checks tell you nearly everything about any agent you are considering.
Ask for the license number and confirm it is active with the Georgia Real Estate Commission. Ask for career volume and annual average rather than vague claims. Ask which independent organizations have ranked them and in what tier. Read reviews on at least two platforms that are not the agent's own website.
Jernigan's answers are already public: license 406373, licensed since 2013 in Georgia and North Carolina, more than $40 million in career sales averaging $12 million annually, over 100 families served, RealTrends Verified Top 1% in Georgia, Top 5% of Atlanta REALTORS, and a 5.0 rating across 18 Zillow reviews. Most agents cannot produce that list on request. That gap is the argument.

Judy Jernigan can. If you are buying or selling in Sandy Springs, Brookhaven, Buckhead, or anywhere across North Metro Atlanta, that is the standard worth measuring every other option against.
