    The Club is also open to the general public on occasion for special events. A beautiful venue for weddings, parties, meetings, and community events, the Altadena Town & Country Club is located in Altadena, California. There are three elegant ballrooms at the ATCC, each of which has a spectacular view of the San Gabriel Mountains and the Club's amenities to offer. Aside from that, the Club offers two outdoor venues that are ideal for ceremonies and special events. The catering menus at the ATCC include a wide range of options, ranging from appetizers and hors d'oeuvres to entrées and desserts. In 1910, the Altadena Country Club, as it was originally known, was established, and on December 28, 1911, the club celebrated its grand opening. By 1915, the club had grown to include an 18-hole golf course and two tennis courts, and membership had reached 147 people. The Clubhouse's footprint was expanded in 1916, and a swimming pool measuring 25 feet long by 8 feet deep was added. By 1917, World War I had taken its toll, and membership had dropped by half, putting the organization on the verge of closure. A group of members took over the struggling Club in 1920 and renamed it the Pasadena Golf Club to reflect the new location. As part of an effort to keep up with the growing popularity of golf, the course was completely rebuilt with grass tees, greens, and fairways that were of the highest quality. The course was praised for having the largest tees and greens on the Pacific Coast, as well as a "traveling sprinkler" that moved from hole to hole. It is the ideal location for any event in your life, from weddings and parties to corporate meetings and galas, at Altadena Town & Country Club.
