Wonfor, 34, joined the firm in February 2009 as an administrator and worked her way up to management.
Having progressed to trainee cataloguer and valuer in its pictures department, five years ago she became auction manager and associate director.
Three years ago the West Norwood auction house launched a strategy to focus on 10 specialist art and antiques sales and move away from general auctions.
Wonfor said: “2018 was the first year for our new sales schedule. My focus is to refine this strategy and cement these specialist sales and establish our reputation in these areas.”
She added: “I joined the company when there were just 12 people and we are now 30. Roseberys gave me the opportunity to learn from the ground up. You get to know how the business works and what doesn’t work. I am very grateful to Ian who has given me a free hand to try new things. He is forward thinking and has been willing to let me run with ideas and test new things out.”
“Loyal and dedicated”
Roseberys was founded in 1987 by Cadzow, 60, who will continue in his role. He told ATG: “Vicki has been very loyal, dedicated and has shown commitment. She loves the business and enjoys the opportunity to expand the business.”
He added: “I personally think succession is very important. If you want to retain keen and enthusiastic people you have to give them opportunity. We are fortunate we have lots of opportunity for people here.
“Last year the opportunity came with the Christie’s South Kensington closure and people became available. We are very happy with these appointments and plan further, measured expansion.”
