Over the next year and a half, the Growing Tree will be adding two new locations in Jackson and Meridian. This is a huge step but, we are so excited to be able to meet the needs for more of Mississippi’s children on the spectrum!  We have set an overall goal of $150,000 to fully fund these projects.  We will be hosting fundraisers throughout the year and partnering with parents and local vendors to open two new clinics with cutting edge resources. Will you partner with The Growing Tree over the next 16 months to help furnish and supply both new locations? We will need tables, chairs, iPads, Computers, Office furniture, indoor playground equipment, curriculum, and so much more to get off on the right foot.

How can I help?  Contact our new Fundraising Director, Summer Slovak, to join the team and help raise the much-needed funds to meet the needs of our rapid growth. She will need volunteers as well as any connections that you may have to local businesses willing to partner with us. Email her at
