New SiteLine President – Cathy Luebke

cathy liebkeCathy Luebke joined SiteLine Exterior Design as it President when we reorganized our company in May of 2014.  She brings 24+ years of management experience, marketing and company growth and development.  Cathy started her career in the United States Air Force where she gained knowledge and hands on experience of management, employee relations and finances. Cathy’s military experience gives her a great advantage of knowing what it takes to get a job done.

After 13 years in the Air Force she joined the private sector and began managing medical practices in the Indianapolis area.  While Cathy’s background is primarily in the medical arena we felt her management skills were a needed piece to help grow SiteLine Exterior Design, Inc.

Cathy is also a leader in her church where she volunteers frequently. She is also known to take time off of her busy work schedule to travel as a missionary to Africa, Columbia and Haiti where she works with AIDS orphans, school children, and women’s ministries. Several times a year, Cathy volunteers her time coaching at Zarvos Leadership and Coaching, a program that helps people reach their potential in their careers and personal lives.

Cathy is the proud mother of two adult children, Ed and Jonathan and one beautiful grandson, Jaxon.

We are passionate about quality design and implementation tailored to each client. Through a process called master planning, we provide our clients with detailed drawings helping them plan
and budget their landscape implementation more effectively.
We are committed to creating a better return on investment for our clients through sustainable design-build practices. We accomplish this through the use of lower maintenance hardscape materials and lower maintenance plants that do not require intensive irrigation over time.

We have a commitment to serve our community with a sense of humility. We volunteer our time and services in various ways to help our neighbors in the community. Please visit our garden at the Chateau Design Centre in Carmel (301 East Carmel Drive) and the St. Maryʼs Catholic Church Grotto Garden in downtown Indianapolis. We share our knowledge in how we interact with our clients and our community. Sharing our knowledge with our clients and community is one of our commitments to helping others understand how the landscape can be beneficial for them.






“We want to thank you for your exemplary efforts at our residence. We had never worked with a landscape architect.

We now sit back and look at what used to be a hopeless space and wonder why we did not do this earlier. Something is in bloom 9 months out of the year. We have spectacular colors that have brought life to what used to be green and brown space.

What we really appreciated is how you helped us understand each plant, its purpose and how it would compliment the other. You shared your vision with ours and the result was an investment made that we will reap rewards from for years to come.”

“As part of the comprehensive re-design of a commercial structure in Carmel, Stefan Luebke of Site Line Design, Inc. was challenged with transforming an existing parking area into a dramatic courtyard garden for the Chateau Design Centre.

His design melded several functional and aesthetic requirements with the old world European architecture of the Centre. Stefan’s design work was instrumental both in obtaining Planning Commission approval, and in the awarding of the Carmel Chamber of Commerce 2009 Look Award for best commercial renovation.”
