About TTHA
As Head Butler at The Lanesborough, London, Robert was responsible for setting up and training the Butler department where outstanding service led to an average yearly occupancy of over 90%. During his six years at The Lanesborough Robert developed many of the systems, standards and training which has kept this hotel at the forefront of the luxury hotels of the world.
During his time at The Lanesborough Robert was asked by Rosewood Hotels to set up and train the Butlers at The Dharmawangsa Hotel in Jakarta. Very shortly after its opening The Dharmawangsa became renowned in South East Asia for its high level of guest care and attention to detail, this confirmed Robert’s belief in his training methods and encouraged him to form his own company.
