Mr Bartley joins from LSL Property Services, where he spent six years as a regional director in the north.
Prior to this, he spent 10 years with Sesame Bankhall Group.
Mr Bartley said: “I was attracted to Tenet Group due to its exciting growth plans for the future.
“The financial strength of Tenet provides a secure platform for the business to expand and it’s clear that the group has capitalised on this, going from strength to strength over the last two years.
“This gives me a really good base to help Tenet to increase its market share.”
Tenet’s adviser propositions director, Simon Broadley, added: “With David’s excellent track record he will be a real asset to our business.
“He has a history of recruiting firms of advisers that develop and grow, which in turn attracts new firms who want to benefit from the breadth of support and assistance that Tenet Group can offer.”
Last month Tenet Group revealed it had signed a five year contract with Intelliflo for the provision of Intelligent Office to its network of over 1,300 investment and mortgage advisers.
