The Cassina Group


I am a real estate expert with The Cassina Group, LLC. I focus primarily on sales on the Charleston peninsula, Mount Pleasant, West Ashley, Sullivan's Island, Daniel Island, and Isle of Palms. I have been successfully selling residential real estate full time for 24 years. I have had the honor of helping hundreds of buyers and sellers over the years. Making and maintaining relationships through my business motivates me. I have been licensed in the beautiful states of North Carolina, Colorado, and South Carolina. I hold CRS and SFR designations. I hold a BA degree from the University of Georgia, Grady School of Journalism, in Public Relations/Marketing. I feel privileged to work for The Cassina Group, where we all love what we do and who we work with. We are fortunate to provide cutting edge technology, which ultimately makes searching simple for our buyers and provides maximum exposure for our sellers!

During my 25 year real estate career, I have bought and sold 12 personal homes. I have renovated most of them, so I like to think I have an eye for opportunity and improvement. I enjoy helping my clients with vision, enabling them to find and create their dream home.

A native Charlottean, I moved to Mount Pleasant in 2004. My entrepreneur husband,Trey, our 2 beautiful children, and our 2 dogs adore living next to Shem Creek. In my spare time you can find me in the yoga studio, on a paddle board, on a boat, on the beach, dining with friends, or at home with my family.

I love where I live. I love everything this city has to offer...a rich culture, an amazing history, beautiful architecture, endless beauty, perfect beaches, outdoor activities galore, mind boggling arts, an amazing culinary scene, and just great people. Helping people make the Charleston area their home makes me happy.

Whether you are searching for a second home on Charleston's fabled peninsula, need to sell a property on one of our beautiful beaches, or looking to relocate your family to one of the Lowcountry

"Garrett has represented me in both buy&sell capacity in 3 complex transactions & her knowledge & professionalism are the reasons for the successful outcome of each. She is creative & tenacious & her communication style succinct. Her understanding of where the focus should remain throughout the buying and selling process. Made all the difference in my ability to maintain perspective when challenges arose. Garrett's decades long success in real estate is a testament to her superb people and negotiation skills. I have recommended Garrett highly and often over the years and would not consider a real estate transaction without her. She is a true house whisperer."

"Working with Garrett to buy a home in Charleston was truly a great experience. As a Realtor, I probably am not one of easiest clients to work with, but she was great. She is thorough, responsive, and has great knowledge about all the areas we considered. Garrett Rust is an awesome agent to work with!"

Carol Miller

"Garrett is a seasoned professional and was indispensable in our process of finding a new home...She listened well to our needs, did thorough research and worked with us to put together a good list of homes for us to see when we arrived. She never wasted our time. She is highly responsive, straight forward and knowledgeable."

Anne Janas

"When I say Garrett goes above and beyond, I really mean it. My family and I were on vacation overseas and Garrett Rust was expecting her second child at any moment. A vacation home we were searching for went on the market and she went out of her way to take pictures and videos of the home we could not physically see due to the fact we were 5,000 miles away. We fell in love with the property and location, instantly. As soon as we came home we had our closing 2 weeks later. If the house of your dreams is out there, Garrett Rust will find it for you, hands down."

Margaret and Giouse Coppola

"Garrett has handled multiple transactions for me and whether I am buying or selling, she has handled each one with ease. Garrett is wonderful to keep you updated during the process from the date you put in an offer to the date of closing. She is always working for your best interest."

Cathy Ulber

"Garrett is a top-notch professional. I couldn't have imagined anyone else going to the lengths she did to ensure our family found the perfect home to purchase in a matter of days. Garrett Rust goes above & beyond a typical realtor."

MaryPat Calvert

"Garrett is the best! She was able I show me houses that were not even on the market and she never pushed any property just wanted to find the right one for our family....Not only did she get us through the closing process during a 1,000 year flood, she has helped with everything from finding a contractor, to a dentist, to babysitter. I honestly cannot recommend a nicer, more knowledgeable, more easy going real estate agent."

Gina Yeager

"Searching and finding a second home in the Charleston area was the most simple transaction we have ever encountered and we contribute it to Garrett Barber Rust. Her knowledge of the area, her ability to know what we were looking for that would fit what we needed as we live in LA, along with her embedded strength of market trends is the culprit as to why she is remarkable as a Real Estate Agent and Expert. We trust her so much, we bought a home sight unseen over the phone as she knew it was exactly what we needed...."

Cathi Crutchfield-Jacobs

"Garrett's market knowledge resulted in us living in our dream house. Her experience, drive and advice made the process smooth. We give her 3 thumbs up.!!!"

Eric Selle

"Garrett was a tremendous help in selling our home. She is knowledgeable, professional, courteous, and very persistent. Garrett had my home in a bidding war within 24 hours after listing, and under contract within 48 hours after listing, $32,000 above listing price!!! Hire her now, no question, trust me she will get the job done for you and do it well. I can't say enough good things about Garrett. She is a pleasure to work with."

Jesse Strauss

"Garrett is the most professional, personable, efficient, knowledgeable and diligent agent I have worked with in years. She truly represented my interests, and made the transaction smooth, effortless, and timely. In many instances, she went above and beyond to make my role as a remote seller thorough, and most importantly, easier."
