Martha Jaffe

Job Titles:
  • Director
Martha Jaffe is proud and happy to be a new member of this inspiring group of people. As an Adopt-A-Road volunteer, her interests lie largely in keeping litter off of our roads, trails, and waterways. She does this by "plalking", which is picking up litter while walking, preferably with a friend or two. Another strong interest is stopping litter before it begins by encouraging everyone to secure household trash in tied bags, and shuttered securely in bins. Martha would like to raise awareness of these simple habits, believing that most people do not litter purposefully. (Windy trash collection days are often the culprit!) Another passion (yes, passion) is kitchen composting, for the benefit of keeping kitchen waste out of our water sanitation systems, as well as having nutrient-rich "black gold" for our gardens. She would like to raise awareness for this simple,and easily adoptable habit as well. Martha is an avid gardener interested in maintaining a pond, native plants, pollinator-friendly gardens, and the avoidance of insecticides. Truthfully, she is also just happy to grow anything that the deer do not eat. Martha and her husband Jed have walked, plalked, and cherished The Muddy Branch Woods behind their home for 27 years. Jed is an avid beekeeper and they are the proud parents of two fine sons. When she isn't plalking she is a Substitute Teacher for Montgomery County Public Schools. [Board member since 5/1/2021]
