Mark Seib leads the firm’s Midtown and Tucker offices. With a passion for innovation and
excellence, he guides the firm in adopting cutting-edge technology and streamlined
processes to deliver modern, welcoming experiences for clients.

A respected leader in the legal and real estate communities, Mark is a past President of
the Georgia Real Estate Closing Attorneys Association (GRECAA), and has served on the
Stewart Title Agency Board of Advisors and the CenterState Bank Midtown Board of
Advisors.

Mark earned a B.S. in Accounting with a minor in Literature from Birmingham-Southern
College in 1991. After college, he spent a year teaching English at the Technical University
of Kosice in Czechoslovakia, then returned to the U.S. to earn his J.D. in 1995. During law
school, he distinguished himself through moot court competitions and clerkships, even
contributing to a case argued before the 11th Circuit Court of Appeals.

With nearly three decades of experience in real estate law, Mark has developed sharp
instincts for managing closings and keeping deals on track. His strength lies in
anticipating and resolving issues before they escalate, an approach that defines both his
team and Ganek’s broader culture. Under his leadership, the firm fosters an atmosphere
of warmth and hospitality, paired with a deep commitment to service, efficiency,
responsiveness, and consistency.

Mark is especially proud of his goal to position Ganek as one of Atlanta’s top workplaces.
He finds real estate law particularly rewarding because of the trust clients place in him
and his team, and the opportunity to make each closing feel special and meaningful.

While leading Ganek is one of Mark’s passions, he also enjoys gardening, cooking,
traveling, college football and exploring national parks with his husband, Ted. They live in
LaVista Park with their beloved dogs, Niko and Simon.
