Company Trip 2024, IAS Advisoryiasadmin

IAS Advisory enjoys beach getaway trip to charming Cha-Am

IAS Advisory recently returned from its annual company outing! The team enjoyed three days, from 17-19th May, in Thailand’s Phetchaburi province, near the famous beach getaway of Cha-Am.

We stayed at the lovely Vela Villa resort, located between the beaches of Chaosamran and Puak Tian, which is an area still largely untouched by tourists.

As part of the firm’s ongoing expansion we have recently welcomed several new joiners, and the resort provided the perfect balance of exclusivity and privacy needed for connecting new teams and building relationships and was an ideal place for us to relax and unwind.

The trip afforded us the opportunity to fully recharge our batteries ahead of another really busy year, as well as undertake various joint exercises and team-building activities in an ideal beach retreat setting.

Party activities included football, karaoke, pool/snooker, swimming and of course lots of eating, including several delicious BBQ dinners! These in addition to staff feedback and development sessions, which focussed on inspiring collaboration and engagement and creating a healthy and positive work environment at the firm.

The IAS Advisory team is already looking forward to its next adventure!
