Pendlebury had been leader of HOSPA's membership and events office, where she had worked alongside Weldon to promote the association and deliver events such as HOSPACE and its IT directors gatherings.
Prior to joining HOSPA she was vice-president and general manager of Agilysys, before which she was director of the Penrose Partnership where she was part of the rebranding team that changed the British Association of Hospitality Accountants to HOSPA.
HOSPA chairman Chris Upton said: "Jane Pendlebury was the unanimous choice of the HOSPA Board - she is a natural successor to Carl Weldon.
"Not only has she excelled as head of HOSPA's Membership and Events services, she has also proved to be an excellent ambassador for the Association, supporting Carl at key meetings both in the UK and overseas. She is well-known in the hospitality industry and brings with her a wealth of management experience and knowledge."
Pendlebury added: "I am thrilled and honoured to have been given this exciting opportunity. I want to continue where Carl left off, and ensure that we focus on HOSPA's core objectives - namely, in the areas of professional development and membership, whilst not forgetting other key services - such as our prestigious HOSPACE conference and exhibition, regional and London meetings, and our monthly 'Overview' magazine."
She confirmed that HOSPA had secured a £10,000 Savoy Educational Trust grant, which it plans to match, to further develop its revenue management courses.
