Hana and Christi are sister-in-laws who have had a dream of opening a preschool together since they met over 10 years ago. Hana and Christi have attended research-based Nature Explore trainings that support comprehensive learning with nature. They are working towards making Treehouse Tots Preschool a Nature Explore Certified Classroom. They have both completed over 15 hours of health and safety training that includes: Pediatric First Aid, Pediatric Cardiopulmonary Resuscitation (CPR) and Preventive Health Practices. They have been thrilled to bring on two teachers who both help to make Treehouse Tots a brighter place.

Christi Lewkow

Her childhood days were spent exploring nature, whether it be running around barefoot catching ‘mudbugs’, building tree forts, putting on neighborhood plays or helping her mom in the garden.

Nadia Passanisi

Nadia Passanisi was born and raised on the central coast of California where her love for the ocean and mountains began. She grew up surfing in Morro Bay and hiking the hills in San Luis Obispo. Wanting to experience a bigger city and more of the SoCal weather, she recently relocated to the LA area. When not teaching, you can usually find her enjoying the beach, rock climbing in the Santa Monica mountains, or camping all around California. On the rare day when the weather outside is gloomy, she loves to bake inside. In the summer of 2019, she spent six weeks traveling all around the world where she was able to experience many different cultures and people. While she loved that experience, she is excited to be back in the classroom teaching.
