Summer Auerbach
Owner
Rainbow Blossom Natural Food Markets

Summer Auerbach is the second-generation owner of Rainbow Blossom Natural Food Markets, a family-owned natural foods retailer founded in Louisville, Kentucky, by her parents, Rob and Pumpkin Auerbach, in 1977. Summer literally grew up in the natural foods industry. In 2004, when her father became seriously ill, she returned to Louisville to lead the family business. Under her leadership, Rainbow Blossom has grown into a six-store operation and earned recognition both throughout the Louisville community and across the natural products industry.

Summer was honored with the 2023 Family Business Award and named the 2016 NAWBO Louisville Large Business Owner of the Year. She is a graduate of the Bingham Fellows program and has been recognized as one of Louisville Business First’s “Forty Under 40.” Under her leadership, Rainbow Blossom has repeatedly been named to Business First’s Fast 50, recognizing the region’s fastest-growing privately held companies.

Rainbow Blossom has also earned numerous national industry honors, including being named a 2026 finalist for the Organic Trade Association’s Organic Retailer of the Year, WholeFoods Magazine’s 2019 Retailer of the Year, INFRA’s 2019 Sales Growth Award and 2018 Innovation Award, Natural Foods Merchandiser’s 2014 Retailer of the Year for Sustainability, and Vitamin Retailer Magazine’s 2012 Retailer of the Year.

Beyond Rainbow Blossom, Summer is deeply engaged in both her industry and her community. She currently serves as Secretary of the Board of Directors for the Independent Natural Food Retailers Association (INFRA), a national trade organization representing independent natural food retailers across the country. She also serves on the Board of Directors of the Community Foundation of Louisville.

Summer previously served as a trustee and Board Chair of the Olmsted Parks Conservancy, where she had the distinction of becoming the organization’s first third-generation trustee, following in the footsteps of her grandmother and her father.

Summer is married to attorney and former Louisville Metro Councilman Brandon Coan, and they have an 8-year-old son, Simon. At her core, Summer is passionate about independent business, community, and carrying a family legacy forward while continuing to evolve it for the next generation.

Her Jewish journey was shaped by summer camp, youth group, and early leadership experiences. She attended Camp Livingston and GUCI, where she formed lasting friendships and traveled to Israel with her GUCI group through NFTY Summer in Israel in 1998. Back in Louisville, she became active in TILTY, eventually serving as chapter president and earning a seat on the Temple Board of Directors. She also began giving back at a young age, helping her grandmother fundraise for the Klein Center at the Temple.

After returning from Israel, she decided to become a bat mitzvah as her senior project at St. Francis High School. With Rabbi Rapport as her advisor, she learned her Torah portion and planned a service filled with camp and youth group friends. On her 18th birthday, she became a Bat Mitzvah surrounded by the Jewish community and friendships that had helped shape her journey.

Today, Josh is married and lives in Washington, D.C., where his daughter recently celebrated her Bat Mitzvah at Temple Sinai.

Vice President of Sales & Services
Davis Jewelers

As Vice President and co-owner of Davis Jewelers — Louisville’s Largest Fine Jeweler — she works alongside her father and CEO, Hank Davis, helping lead the family-owned business into its next generation. Over the past 22 years, Ashley has worked in nearly every area of the company, giving her a deep understanding of operations, sales, custom design, client experience, and leadership.

Today, she oversees the store’s buying team, jewelry and watch service centers, and day-to-day sales operations, all while remaining closely connected to clients on the showroom floor.

Ashley has been married to her husband, Jay, for 19 years, and together they are raising their two children, Asher, 16, and Juliette, 12. Her connection to Judaism has been a meaningful and enduring part of her life, shaping both her family and her commitment to community. She is especially excited for the opportunity to share how that connection has remained present throughout her life, the importance of raising her children with a strong Jewish identity, and what it means to continue strengthening and supporting the Jewish community for the next generation.

Jewish summer camp also played a formative role in Ashley’s own identity through her years as both a camper and counselor at Camp Livingston in Bennington, Indiana. Seeing her children now share that experience has brought it full circle, providing an important sense of Jewish connection, belonging, and community — especially while currently living in a city with a smaller Jewish population.

Jared Rouben
President & Brewmaster
Moody Tongue Brewing Company

Jared Rouben launched the culinary brewing company Moody Tongue in Chicago in 2014, applying a chef’s mindset to highlight flavors and aromatics in balanced beers. A graduate of Washington University in St. Louis and the Culinary Institute of America, Rouben worked in acclaimed kitchens across the country, including the MICHELIN-starred Martini House in Napa Valley and Thomas Keller’s three-MICHELIN-starred Per Se in New York City.

After completing the Siebel Diploma Course in Chicago, Rouben served as Brewmaster at Goose Island Beer Company’s brewpubs, where he developed the Farmers’ Market Series and Chef Collaboration Series with chefs including Rick Bayless, Stephanie Izard, and Paul Kahan. These experiences helped shape the culinary brewing philosophy that became the foundation of Moody Tongue. Rouben later led the creative development of Moody Tongue’s beer portfolio and served as an Examiner for the Master Cicerone program and as faculty at the Siebel Institute.

In 2016, Rouben and CEO Jeremy Cohn opened The Tasting Room at Moody Tongue in the brewery’s original Pilsen location. The space earned the Jean Banchet Award for Best Bar in 2019. Later that year, they relocated operations to Chicago’s South Loop to expand production and open The Bar and The Dining Room, both recognized in the MICHELIN Guide from 2021 through 2024.

Moody Tongue continued to grow with the opening of Moody Tongue Sushi in New York City in 2023, Pizza Studio Tamaki in 2025, and a second Moody Tongue Sushi location in West Palm Beach later that year.

Rouben’s Jewish story began growing up in Louisville, where experiences like cotillion and celebrating bar and bat mitzvahs alongside friends gave him an early connection to the Jewish community. That connection deepened through Federation programs, including a trip to Israel, and through his involvement in BBYO during high school.

Looking back, Rouben recognizes how deeply the Louisville Jewish community shaped who he is today. It gave him a sense of belonging, instilled a lasting sense of Jewish pride, and provided experiences and relationships that helped shape the path he would ultimately take. For Jared, so much of who he is today started here, in Jewish Louisville.
