A Fun-Filled Day At The Annual Terra-Petra Summer Picnic

Thank you to everyone who came out to the annual Terra-Petra Summer Picnic this year.  It’s always nice to connect outside the office with friends, family, co-workers and colleagues who help make Terra-Petra successful. It was a wonderful event, and a great day to be outdoors enjoying the summer weather.

The event was held this year at Rancho Los Cerritos in Long Beach, and we couldn’t have asked for a better setting.  The day was made extra special with delicious food from Marhalls’ Bodacious BBQ and live music and entertainment supplied by Common Allies along with a fun, and competitive, few rounds of bingo.

Thank you again to everyone who was able to join us this year, and thank you for being a part of Terra-Petra’s continued growth and success.

We look forward to seeing you all at the next Terra-Petra event!
