Our Mission


Tandem's mission is to create intergenerational connections in which high schoolers can benefit from seniors' mentorship while allowing seniors to stay connected with the younger generation.


According to recent research conducted by the Stanford Center of Longevity, interaction with seniors can nurture further “development of social skills and sense of purpose.” High schoolers are uniquely incentivized to commit to these connections given their graduation service requirements, and an app such as Tandem allows them to complete these obligations in an efficient and impactful way. While service requirements will likely be the catalyst for their participation, we believe that the intangible benefits of these connections will encourage sustainability and longevity within their relationships. In this way, Tandem is helping to create a generation of young, compassionate, and inspiring changemakers.


The elderly can gain a greater sense of “fulfillment and purpose in their own lives” through these connections. By regularly listening to their partner's successes and struggles, offering insight, and sharing their wealth of experiences and learnings, seniors can enrich their partner and see that impact on a youth's life. In addition, Tandem offers a unique way for seniors to pass on valuable memories that could otherwise be lost to time, further establishing continuity between generations.
