The founder of Lappin Properties, Sissy runs one of the most 

successful real estate firms in Houston; her 

company was recognized by the Houston Business 

Journal as "#1 in most expensive homes sold." Sissy 

delivers exceptional, one-to-one personal service and 

she does it all from one desk, with one laptop. 

Though highly respected in her industry, Sissy is 

considered a renegade because she is a one-man-show and not a large firm. 

Now Sissy has taken the proven system she used to build her home sales 

success and has created the innovative ListingDoor process that makes it easy for 

homeowners to price, list, market, and sell their own homes. From her beginnings 

in one of the worst real estate markets in recent history, she has successfully 

consulted and negotiated profitable deals all over the country. 

Sissy has a wonderful warmth and enthusiasm that translates into her writing. 

She lives with her husband and two children in Houston, TX.
