About Me

With a background in commercial real estate and commercial development, Johnna
McQuillan’s real estate career has been 25 years in the making. Johnna spent several
years working for the first female Registered Professional Land Surveyor in Texas, and
she has extensive business management and property tax consulting experience.
Johnna was born in North Texas and raised by several generations of ranchers. Her
family relocated to Austin in the early 1980s, when her father went to work for the Texas
Railroad Commission. The family remained heavily involved in the Cutting Horse
industry, and still is to this day. 


As a youngster, Johnna’s favorite pastime was competing in pageants. At 16, she was
fortunate enough to be part of the Miss Texas Teen USA Pageant; at 18, she competed
in the Miss Texas USA Pageant. Johnna continues to mentor and coach young women
as they pursue their dreams.


Johnna studied International Business and Fashion Merchandising at the University of
North Texas in Denton. Four years ago, Johnna and her husband, Nathan, relocated
their family to North Texas from the Austin area after a brief move to West Texas.
Johnna and Nathan have three daughters: Katy is a recent graduate of Tarleton State
University pursuing a career in Broadcast Journalism; Jessi is a junior at Gunter High
School, works part-time at Starbucks & is a hospital volunteer; and Savannah is a 6th
grader at Gunter Middle School, participates in choir and various UIL events.

Johnna is no stranger to relocating and knows firsthand how difficult and stressful it can
be.  She enjoys helping clients meet these challenges head-on with the high standards
of service, sales, marketing strategies, cutting-edge technology and support Ebby
Halliday Realtors has provided since 1945.
