ST. LOUIS - April 22, 2026 - PRLog -- Calder Capital, a nationwide Mergers and Acquisitions Advisory firm, is proud to announce the successful acquisition of Door Service, Inc. of St. Louis, Missouri, by The Rapallo Group of St. Louis, Missouri.

The Rapallo Group, led by President and Owner Pat Noles, is a St. Louis-based private investment vehicle focused on acquiring and operating lower middle market businesses.

The Rapallo Group engaged Calder Capital's Buy-Side team and ultimately acquired Door Service, Inc.

Founded by Art and Laquita King, Door Service, Inc. has built a strong reputation across the St. Louis region for installing and maintaining high-quality commercial doors, entrances, and for providing hardware solutions. After Art King's illness, second generation owners Tim King and Tod King stepped in and grew the business with the help of their brother Mark.

Jakob Simonds of Calder Capital served as the Lead Mergers & Acquisitions Advisor to The Rapallo Group. Serving as Lead Director was Hannah Nabhan of Calder Capital, and the Lead Associate was Dominik Bepristis.

Calder's Buy-Side team generated 18 off-market seller introductions, leading to 11 client pursuits, two offers on unique businesses, and resulting in the successful acquisition of Door Service. Calder Capital was engaged in mid-June, the Letter of Intent was executed in September, and the deal successfully closed in February.

Regarding his experience with Calder Capital and Jakob, Noles stated, "I enjoyed working with the whole Calder team, and I often refer them to people who are considering Buy-Side representation."

Tim King spoke to his experience and stated, "selling a business is an interesting experience, and they were helpful."

Sam Scharich, Calder's Buy-Side Managing Director, mentioned, "Door Service is an outstanding company with decades of reputation in the St. Louis market, and we're excited to see it continue to grow under Pat's stewardship."
