A: Tulsa just feels like home! I grew up in the area and have made memories all over town, from riding the Zingo at Bell’s every summer, to watching my favorite artists perform at the BOK Center, to starting my career downtown surrounded by the beautiful Art Deco. Also… Warehouse Bar & Grill 💔 R.I.P.

Whether you are an activist, artist, runner, bicyclist, reader, parent, advocate etc. you will find a group of individuals who share your love. The resourcefulness of the people of Tulsa to make such an impact is inspiring and should be a model for other cities.

A: Life’s Better When You’re Growing: The Enduring Education of Donna Willis

Coming up with a title for my autobiography required a bit of self-reflection, but I didn’t want to overlook the forest for the trees, so to speak. Looking back, I can see that my happiest times have involved growing. I have a passion for horticulture and love growing flowers and veggies. I enjoy growing my knowledge through formal education and studying my passions of horticulture and natural healing. And, I am having so much fun with my growing family, which now includes 3 amazing grandchildren and an adorable baby nephew!

A: The Gathering Place! It’s a beautiful park and there are so many amazing features and options for family fun.

A: If I could have one super power I would wish to be MAGIC. And I would conjure all types of powers for good in the world. And the dishes and laundry would always be done.

A: I grew up in a small town. At an early age, I recognized that the interconnections of families, neighbors, and the entire community plays a vital role in supporting young people. One of my favorite things about Tulsa is that you can see that same type of community support here, even though it is a much larger city. There are many disparities that exist for too many young people in Tulsa, and I see Tulsans working every day to make it a better place where all young people can grow up healthy and able to take hold of every opportunity. The work that we get to do supports all young people to fulfill their highest potential, and the enthusiastic collaboration in Tulsa makes it all possible.

A: Can I choose 146? If I can choose 146 folks, I’d bring all the youth I had the opportunity to work with in Carrera class of 2021 together again. I’ve never laughed more with or learned more from anyone (especially you, 7th hour) than this remarkable, reflective, courageous, hilarious group of young people. But if I only get one, I’d have to pick Kurt Vonnegut, because he was clever and charming and profound all in the same sentence.

A: The people. I have the privilege of working alongside some of the most heart-centered, youth-driven, intentional folks in promoting adolescent sexual health and in my personal life. I’m grateful for the change makers, the social workers, the advocates, the organizers, and the mentors I learn from every day. Tulsa is transforming because the people just do NOT quit.

A: If I had to be on a reality TV show I think it would be Guys Grocery Games. I love Guy Fieri and come from a family of chefs. I think it would be great if we could all compete together as a family and see what shenanigans we get into! I definitely would not be the best cook but think it would be a fun challenge to tackle as a family!

A: One of my favorite things about Tulsa is the small town feel, but big city benefits. We have an incredible arts scene, great local businesses and restaurants, amazing concert venues that attract great talent and so much more. There is always the opportunity to find something new. I love the people I’ve met and come to know in Tulsa and the people who are working hard to make it a better place for everyone.

A: I have always wanted my own talk show! The current working title is “Tea Time with Tammy” and here is my lineup for the first episode full of laughs, music, science, and in depth interviews with celebrities!

  1. Introduction where I share the names I go by as a Nonbinary person! I use the names Tammy and T so it’s best to get that lesson out of the way first to avoid confusion 🙂
  2. Comedic skits and stand up sets from Ilana Glazer and Michelle Buteau to warm up the crowd.
  3. Science experiments with STEM queen and style Icon Ms. Frizzle from the Magic School Bus
  4. Belly Dance tutorial from my childhood Pop idol Shakira where she’s impressed by my skills and takes me on tour with her
  5. Fashion segment with a style panel of Billy Porter, Alok Vaid Menon and my Mom.
  6. Megan thee Stallion will close out the show with some music from her new album

I may be biased because it’s my show, but I’d watch it! Hope you would too, those celebrity appearances ain’t cheap! 🙂

A: It’s the great mixture of small town and metropolitan. There’s a little bit of everything you would find in a city yet the nights are quiet and peaceful like a small town. I also love and support the growing diversity we have from all the people who make Tulsa great with their cultures, languages, food and individuality. The diversity makes Tulsa so much more culturally rich and I’m excited to see the progress and important conversations we as Tulsans have together.
