Barbara Yaroski, Vice-President


Alison Craig, Director

Barbara is a retired Project Estimator who worked in the Upland & Wetland Restoration Industry. A love of trees was a personal passion that grew out of Barbara’s work as a Production and Sales Manager at a Garden Center. Her computer skills became an asset at the OUFC as Barbara initially designed and created the OUFC website which she still in part maintains today. Sharing her love for and concern for trees with the broader community and working with the OUFC and it’s partners has been a rewarding way to remain engaged in retirement.
