Meet the Founder
A thoughtful, elevated childcare experience led by deep care and credible expertise.
Onsite Sitters was founded to give families and event hosts a discreet, polished childcare solution that feels calm, seamless, and genuinely trustworthy from the first conversation through event day, whether the gathering is joyful, formal, or deeply tender.

London Thatch
Founder of Onsite Sitters
London brings a rare blend of warmth, professionalism, and child-centered expertise to every event. With training rooted in psychology, behavioral health, and early childhood development, she created Onsite Sitters to feel intentional from start to finish: calm for parents, polished for hosts, and deeply supportive for children.
Her experience at Children's Hospital Colorado as a Behavioral Health Specialist shaped the safety-first, attentive standard behind the brand. The result is childcare that feels elevated and seamless while still grounded in real trust, emotional attunement, and thoughtful preparation.
