THE Henley Bridge School is to reduce the number of its weekly sessions.
Jon Green, who launched the business in 2011, says it is not making enough money to support his young family.
The former City banker and civil servant, 37, is about to start a new job as a financial planner for Invesco Perpetual in Henley.
However, he says he wants to keep the school going and will continue to run classes at least once a week.
The school has more than 500 members, about 200 of whom are novices, and was running classes on three or more days a week, depending on demand, and offered private group lessons.
Mr Green and his wife Victoria, who live in Nettlebed, have two children, Edward, two, and Victoria, who is one.
He said: “I made the decision with some regret because I have really enjoyed running the school but it is the right thing to do at this time.
“I’m at the stage where my family has to take priority. My new job offers us financial security, which is what’s important. On top of that, bridge is often an evening activity so I would hardly see the children once they got older and started going to school.
“I’ve had a lot of emails from members congratulating me on getting the job. They understand my decision and I am very grateful for their support.
“I will miss the people the most. There have been some wonderful groups and characters and teaching them is both enjoying and rewarding.”
Now Mr Green will hold workshops at the Red Lion Hotel in Hart Street at 7pm every Tuesday. These will include formal tuition and supervised play.
There will also be a “bridge in a day” course on six Saturdays a year at Hennerton Golf Club, near Wargrave.
Mr Green hopes to organise one-off seminars and fixtures, including the school’s annual charity bridge drive at Harpsden village hall.
Some of his pupils plan to hold informal bridge matches every Monday evening at the Red Lion.
