Sister Synergy is a fresh, youth-led venture on the North Shore Edge, launched by two sisters born and raised in the community. These savvy teen entrepreneurs offer babysitting with certified training, pet sitting, intro piano lessons, sewing classes, and home care—like plant watering and mail checks—bringing a burst of energy and reliability to local families. Armed with Standard First Aid, CPR, and Home Alone certifications, they’re available by appointment only.
