What would be a better expression for the following?
Kudos to Peter FOR his volunteering FOR Sunday school FOR both Jan and Feb.
There certainly are many OTHER ways to express my gratitude to Peter's help. But I feel a "lengthy" expression can easily diminish the "sense of gratitude" I wish to convey so I am hoping for a concise expression that gets right to the point but won't be hampered by the repetition of 3 'for' in a row.
Details: I was suggested to add more details so that people can provide on-point corrections: Peter, when approached, chose to help out church's Sunday school (but not the outreach programs due to scheduling conflicts) and volunteered for two months' time instead of the regular one month. His spirit exemplified an exceptional role model at church and I would like to encourage others to emulate Peter by expressing my gratitude to his altruism.
