Nearly two decades ago, Beckie Jacobs set up shop in Webster Groves, determined to build one of the area’s premier ice cream brands, Serendipity Homemade Ice Cream (4400 Manchester Avenue, 314-833-3800). Now, she’s bringing her brand to a new home in the Grove, determined to build on her success and make her stretch of Manchester Avenue a little bit sweeter. “Webster Groves was really good to me for 19 years, but the city has also been very welcoming,” Jacobs says.
