Tammy is a buyer’s specialist of The Dawn Griffin Group at Circa Properties. She brings a wealth of life experiences that inform her approach to real estate. As a military kid stationed abroad for 12 years, she had the privilege of uncovering a love of architecture and art throughout Europe. That sense of curiosity and discovery has permeated all aspects of her adult life. From the ten years she spent in the home renovation business as a hands-on project manager (learning plumbing, electrical, and framing, tiling, and trim work) to building a highly successful HVAC company from the ground up in Nashville, Tammy brings curiosity, passion, and determination to her endeavors.

My experience with home renovations and systems, combined with the business and leadership skills I’ve developed along the way, provide my clients with a unique breadth of knowledge and sense of comfort. I particularly enjoy working with first time home buyers, who really appreciate having someone with experience who can provide realistic pros and cons to renovation projects.

Though born in Spain, Tammy has spent most of her life in Missouri. She relocated to the Historic Shaw neighborhood from Nashville and in 2020 bought a ranch home in South County where she’s wrapping up a major kitchen renovation. She loves to travel and explore and during her off time she enjoys hiking, kayaking, motorcycling, and sewing.

If you are ready to explore the rich architecture and fantastic neighborhoods of St. Louis with a true home aficionado, Tammy will be a valuable resource to you.


Finding a home is never an easy task. I felt so lucky to find my home in St. Louis with Tammy’s help. She was always alert and patient to my demands. With a smile and excellent disposition picked me up day after day until we found the best home for me. In addition to being a very effective real state agent, she is a lovely person that makes the difficult task of find a home seem effortless.

I am a brand new home owner thanks to The Dawn Griffin Real Estate Group. Tammy and her team did an amazing job of walking me through the process. I could tell that they were smart, well versed with the St. Louis market, and legitimately cared about me and my little boy. I couldn’t be any happier with the house that I landed in this unbelievably competitive market. I would absolutely recommend Tammy and her team!
