Dr. Tammy Gray-Steele
Founder/CEO of National Women In Agriculture Association
Founded in 2008 by Dr. Tammy Gray-Steele

NWIAA was founded in February 2008, by Dr. Tammy Gray-Steele who is the founder and Director. The organization is headquartered in Oklahoma City, OK. NWIAA is an agriculture outreach organization fueled by sisterhood and diversity.  

Our vision is to provide vital opportunities for rural and urban communities to sustain themselves through agriculture. We have made it our mission to increase the number of minority participation in the agriculture sector. We believe if we equip our youth for tomorrow while engaging them today, we can increase the number of minority youth going into agricultural careers. NWIAA’s Grass Root innovative and sustainable at-risk-youth programs will build capacity within and at 1890 Land Grant Universities’ Motivate Education Achieve Program (“MEA”).

We also have partnerships with The USDA Programs and 1890 Land Grant Universities. There are 45 NWIAA Current & Pending Chapters.  This number includes sub Chapters within various states.

Rhonda Spencer
Human Resources

Rhonda Spencer, a native of Brooklyn, New York, is a married mother of two, an educator, and an entrepreneur. Her career in education began in 1999 in the New York City Public School system, where she taught in The Bronx and Manhattan. She received her Master’s Degree in Education and a Certificate of Advanced Graduate Studies in Educational Leadership from Cambridge College in Boston, Massachusetts. Later, she became an adjunct professor and student teacher supervisor at East Stroudsburg University in Pennsylvania.

In 2010, Rhonda's interest in agriculture began with her first summer food garden at her home in Pennsylvania. Within the same year, she and her family moved to Virginia for a land and farming opportunity. Although this opportunity did not materialize as expected, in 2020, after relocating to Oklahoma, Rhonda revisited her quest of growing her own food and her interest in farming and agriculture.

Rhonda continued her agricultural journey by growing food on her back porch. With news reports predicting a food shortage and the challenges of obtaining healthy, nutritious fruits and vegetables during the coronavirus pandemic, she grew food not just for leisure but to address the growing uncertainty of food access.

This endeavor presented many challenges, especially in an urban setting. Her desire to learn more about urban gardening and educate her community led her to start the live virtual workshop series “From Seed 2 Harvest.” Initially focused on gardening, the show quickly expanded to cover various stages of growing and storing food, including food preservation, freeze drying, hoop houses, greenhouses, aquaponics, and animal husbandry. The series featured seasoned farmers and gardeners like Kwame Mboya, a local farmer and founder of the NEOKC Farmers Market Incorporated, as well as international guests from as far away as Zambia, Central Africa. The virtual format allowed the show to reach larger audiences and forge relationships with farmers and food sovereignty advocates worldwide, placing "From Seed 2 Harvest" on the global scene. Just as we cultivate to grow fruit, vegetables, and flowers, this is only the beginning for "From Seed 2 Harvest."

In December 2021, Rhonda co-hosted "The Mentoring Klinic" on WOLB AM Radio 1010 in Baltimore, MD, discussing "Community Preparation for Food Shortage/How to Prepare." As Rhonda continued to engage with various groups and study, she realized that farming is a lost art. She believes it is important for our youth to reconnect with the earth and learn the art of growing food. She believes this is the key to sustaining a good quality of life, taking charge of our lives through cultivating good, wholesome, life-sustaining food.

Even as a teenager, she worked on initiatives that supported BIPOC youth, such as organizing mental health seminars for her peers. Her college years would then become a pivotal time, as her research opportunities and participation in programs such as “NewGen Peacebuilders” (a Rotary Club Fellowship, where she studied graduate-level peace studies and worked on a peace project that aimed at reducing youth recidivism in several local communities in her state) would shape her understanding of what it means to engage in peacebuilding and what it truly takes to work toward sustainable economic development.


Qadira graduated at the top of her class with the highest academic and student honors her alma mater had to offer, including Phi Beta Kappa; Omicron Delta Kappa; Omicron Delta Epsilon, an economic honors society; and the Algernon Sydney Sullivan Award, which recognizes a college senior for her virtue and service to her campus and community. In 2019, Qadira graduated with a B.A. in political science and a double minor in religious studies and peacebuilding and conflict resolution.

With aspirations to become a polyglot, she is conversationally fluent in German (B2/C1) and studies Japanese (JLPT N4). Qadira has also traveled to over 16 countries to date, with the purpose of much of her travels focusing on academics or research highlighting social issues in that area. 


Her passion for travel, peacebuilding, and youth empowerment has led her to align with organizations whose mission serves our most vulnerable communities, and whose actions transcend peoples, cultures, faiths, and borders to the betterment of humanity, such as the National Women in Agriculture Association.
