| December 15, 2011- We are very pleased to announce that our family adoption this season was an incredible success! Due to the astounding generosity of our families, friends, and customers, we were able to adopt not one, but TWO families! Your donations allowed us to exceed each family member's wishlist, which was no small task for this family of three and family of seven! In addition to their gifts, each family received a large food basket as well as grocery gift cards. It was such a joy and a pleasure to be able to give these families a Christmas I'm sure they won't soon forget. Thank you so much to everyone who donated their gifts, money, and time to these families! -Katie |
| December 1, 2011- HTP Automotive is happy to share that we will be participating in the St. Anthony Food Pantry Family Adoption Christmas Program this year. The St. Anthony Food Pantry in St. Louis provides food and clothing daily throughout the year to members of their local community in need. By adopting a local family through the Christmas Program, we are able to provide them with Christmas gifts, clothing, and additional food so they may enjoy the holidays in ways that might not otherwise be possible.

| October 15, 2011- The 2011 WALK NOW for Autism Speaks event downtown in Forest Park was a huge success this weekend! Both the 5K run and the 1-mile walk were a blast! Thanks to everyone who came out, donated, and help raise awareness for a great cause! This weekend the St. Louis region raised nearly $1,000,000.00 for Autism Speaks, the nation's largest autism science and advocacy organization, dedicated to funding research into the causes, prevention, treatments and a cure for autism; increasing awareness of autism spectrum disorders; and advocating for the needs of individuals with autism and their families. HTP Automotive is proud to have been apart of this event! Pictured below is part of Team HTP on Walk Day! We were thrilled to have so many join us and missed our long-distance team members and the others who weren't able to be with us on Saturday.
