Denise Peoples

Chief Educational Officer (CEO)

Denise Peoples was born and raised in Los Angeles, California.  She attended California State University, Fullerton where she earned a Bachelor of Arts degree in Communications with an emphasis in Marketing. She was awarded a scholarship to UCLA’s Anderson School of Business where she obtained her certification in “Management Development of Entrepreneurs’.

Prior to opening STEMulate Learning, I owned an Executive Search firm for many years placing Nuclear Engineers and Technology professionals in STEM careers all over the country. I could not understand why it was such a struggle to find talent in the United States. In many cases, I hired professionals from China and India because we could not find subject matter expertise in in our own country. This discovery led me to take a deeper dive into the “Why” which revealed a knowledge and achievement gap in STEM subjects such as Math and Science which needed to be addressed. At that moment, my passion and purpose was revealed. I closed my brick and mortar and opened STEMulate Learning and have never looked back!

Seeking to understand, my travels took me all over the United States speaking to esteemed educators who shared their perspectives, acknowledging that teachers have content knowledge, but struggle to make a connection with children in Math and Science.  They do not know how to make Math and Science fun, engaging and rigorous. My business partner and mentor said, “Teachers teach how they were taught, good and bad”. “In turn, they teach their students the same”. As instructional coaches, we conducted discovery-based orientations with each teacher we worked with that proved his conclusion. As we walked classroom to classroom it became apparent that the missing ingredients is cultural relevance, social emotional learning, and growth mindsets in 95% of the districts we served.


Intentionally leveraging my background as a Master Recruiter, I began to hire Math and Science instructional coaches that look like many of the children present in 90% of the districts we serve. Our instructional scholars joined forces with STEMulate Learning on a quest to make learning culturally relevant, social emotional, rigorous and most of all FUN!

In doing just that, we continue to bridge the learning gaps and students scores began to soar!


Ultimately, our goal is to help 1 million children find their love of Math and Science by supporting both teachers and students. WE WON’T STOP UNTIL OUR KIDS REACH THE TOP!

My passion for physics and math has allowed me to complete a B.S. in Physics at UC Santa Cruz and a M.S. in Physics at UC San Diego. My educational background therefore was highly math intensive and has given me wide knowledge and experience with advanced math subjects including Statistics, Calculus, Algebra, Complex Analysis, and many others.


During my four years at UC San Diego, I served as a teaching assistant, running the physics lab and giving lectures. That experience developed my ability to communicate complicated subject matter to students who felt uncomfortable with physics and math.


I also worked at the Cambridge Learning Center, JEI Learning Center and Sylvan Learning Center, helping K-12 students with all subjects. In these positions I helped students understand and conceptualize SAT/ACT/ISEE math, AP Statistics, AP Calculus, AP Physics, and all other standard math curricula including the Integrated Math 1, 2, and 3.

Raquel Martinez


Raquel Martinez is an experienced educator of 9 years. She is a proud native of South-Central Los Angeles and spent many of her years working with kids there.


Raquel’s motivation and drive to work with youth started in Santa Cruz California. While there she pursued her BA in Mathematics with a minor in Physics. It is there that she realized the disparities and the educational disadvantages minorities faced as well as 1st generation college students. After returning to Los Angeles, Raquel joined the nonprofit City Year in the community of Watts. In this role she was challenged to help decrease dropout rates by targeting 3 key areas: class attendance, behavior, and grades. Ms. Martinez understood that the learning disparities mirrored deeper-rooted issues that affected the community. She worked tirelessly with her teacher and partner to create individual tutoring plans for “At-risk” students. In just 8 months Ms. Martinez raised retention rates in her class by 45% and increased her class's passing rate from 40% to 75% passing.  


Her work didn’t stop there! While working with the Boys & Girls Clubs of Carson, she established John Muir’s first All-Girls STEM Program called I-Chica’s.  In addition, she volunteered with Get Magic which was a women led initiative from Google to provide opportunities to young girls in STEM. Ms. Martinez’s work with both initiatives gave her a once in a lifetime opportunity to bridge both worlds and create an environment which focused on the (4) C’s of Education: Creativity, Collaboration, Critical thinking, and Communication. Ms. Martinez efforts with her Middle School team (I-Chica’s) entered and competed at the 1st Annual “Girls Build” Competition and won 1st Place!  As winners, each participant was provided a scholarship to their college of choice.


Ms. Martinez's work didn’t only target the classroom, it manifested into Sports. Raquel’s passion was always greater than self and she continuously advocates for those in marginalized communities targeting youth who love sports and then leverage those relationships to increase their GPA’S as many of them were struggling academically but excelled in sports. This led her to open her own training camp, Watts Academy with a goal to provide the youth of Watts training opportunities while also delving deeper into academics and personal branding.


Ms. Martinez is a life-long learner who is dedicated to children and will always find creative ways to engage them towards success in academics. Ultimately, engaging youth in what they love to do, then help them find their love of learning.
