Both of our sons(18 months and 3 and a half years) attended the Knowledge Beginning in Tigard, OR. This is the best childcare in SW Portland. We visited a lot of childcare before to decide on this one and we never regretted our choice. The director(Larisa Porsova) was excellent and professional. The teachers were all very nice with both of our sons and surely created some special relationship with them very quickly. The tuition is expensive but you pay for what you get. The other institutions were just so sad and not nearly as organized as Knowledge Beginnings. Several times a week, the childcare brought in some artists or jugglers to entertain the kids with a show. The outside of the childcare is nicely layout and kid friendly. Although I personally would have like to see more shadow spots. My main worry was for my 3 and a half to be challenge and learn a lot. The setting in the childcare was perfect to achieve these goals. I would recommend this center to anyone who is willing to make some worthy sacrifice for the good of their kids.
