Dear Staff,
We have missed you all! We always go to CAS when we are in the Bay Area visiting family. During these past many months, it has been on my boys’ list of top places to visit when places reopen. We can’t wait to visit you the first week of August!
Love, the Siddiqi family

Dear Dr. Scott the Paleontologist
My daughter is a long-time fan of "Dinosaur Train". As we all craved the familiar during the pandemic, my daughter turned to the show for comfort. Thank you for providing a taste of "normal" to our home. Can't wait to bring my family back to the Academy!

Dear Tim Wong
Thank you for introducing us to your amazing Academy. We totally loved spending the day there back in April. Even more importantly, thank you for letting our son "Eeyan" have an opportunity to immerse himself in the wonderful world of nature - at the Academy and at home!
Love, Ken and Mary Anne

I found your lectures on the evolution of human skin color illuminating and fascinating. Keep up the good work!

Dear all the animals in the academy
You guys always made my day! In different ways, each and every one of you were just incredibly adorable and always made me smile! Ever since my first visit at the academy, I knew that donating was a wonderful choice! The African Hall is just spectacular and Claude is extraordinary! Not to mention the magical aquarium section and rainforest exhibit! Everything there is just so interesting and amazing! You guys always made it a cool and wonderful place to visit for me and my family! Thank you super much for helping me learn so much in a fun way! Hope you all stay healthy and happy!
Love, XiAMi

Dear Rooftop Garden,
I love the brilliant colors and varieties of indigenous SF wildflowers, which support sharply declining populations of native bees, butterflies and birds.

Dear Claude
Thank you for being my favorite alligator! I got a little stuffed toy that looks like you at my last visit. You have more friends than just the turtles in the swamp! Thank you for making me smile. I love you!

We are worried about you. You always seem alone and misunderstood. I’m not sure why you stay outside or hover in front of the nest near you. I think you and your girlfriend need a nest. If you want the one nest one then maybe you both have to just move in.

Stanlee, the penguin
After a long year, a failed wedding, covid and problems, I start to giving up. Thank you for exist with all the rest of the penguin family. I see you and the rest of the animals at your instagram - every morning - .

Dear Butterflies.
Thank you for letting me play in your rainforest world. Thank you for landing on my nose and making me giggle. I love the way you fly real high into the dome, and then really low near the pond. I can't wait to see you soon!
Love, Sebastian H.

Dear Academy,
I've been coming to the Academy with my family since before I could walk! I love the penny squisher machines, checking out the "Dory" fish in the tanks, visiting the honeycomb ray, and playing in the gardens. While you were closed, I missed seeing Claude and the penguins. I'm so glad to be back at my favorite museum! Here I am with my Aunty, Grandpa and Grandma.
Love, Kai Hiller (Age 5)
