How can someone get certified to be a grounds keeper? A lot of people (i.e., city, coaches, owners, etc...) won't let anyone but them touch their fields. I understand this. But when they don't do the job, how can someone convince them that they can take good care of it? Is there some place to go and get a certificate to show that a person has the proficiency to grounds keep?

Thank you in advance.

Try talking to the league administators hopefully they can point you in the rright direction

I believe that the certification you are looking would be a degree in turf grass science. This degree has become more and more popular in the last 10 years. This career is often associated with grounds keeping of a golf course, but there are a few who take their education to the fields of professional and semi-professional teams. Also, I've found some interesting books through my local library about this. And as for getting him to see you're capable of keeping the diamond looking nice, maybe keep your own yard in A+ shape. Good Luck!
