Bernadette Kopanski

Throughout her children’s’ active lives, she has always volunteered as a way of keeping in touch with whatever activities/programs they were involved with. She also volunteered in order to support & help make these activities/programs successful. After raising two beautiful & very smart young ladies, she found that she had some free time on her hands. Since she has always wanted to give back to my local community & with some luck from her eldest daughter who obtained her EMT certification from Bulverde Spring Branch Fire / EMS station, she was put in touch with an amazing opportunity to volunteer at Acacia Medical Mission. She is so thankful to be volunteering there every Wednesday afternoon and loving the fact that she is able to help make a difference in someone else’s life.
