About Mrs. Jones


My family started our homeschool journey in 2005 and we have never looked back.  We found THEO when someone told my elder son about it.  We were very new to homeschooling and it almost sounded magical!  My son participated in the band that year and then I started teaching at THEO the next year for just a few hours each week.  Now, I have thoroughly enjoyed teaching Algebra 1, Algebra 2, Geometry and/or SAT Math Prep at THEO for more than 13 years.  I LOVE the consistency and absolutism of high school math.

Additionally, I served as the Nursery Director for 19 years at a local church before stepping down last year to focus on other areas of service.


I have been married to my wonderful husband Dan for more than 30 years.  Our oldest son graduated in UTD in 2015 and now lives and works in OKC.  Our daughter graduated from OSU in 2018 and is now in her second year of medical school.  Our youngest son will be graduating from homeschool in 2021 and pursuing a degree in…something, although we don’t know what that is yet.  My personal interests include gardening, cooking, sewing and playing the piano.

Nathan Jensen returns to THEO as a recent graduate from the University of Texas at Dallas, graduating Summa Cum Laude with a B.A. in Literary Studies with Honors and a Teaching Certification for 7-12 ELA (English). In the spring semester of 2019, Nathan worked as a substitute teacher for Allen ISD and taught as a long-term substitute for two months at Erickson Middle School in Allen. Also, Nathan has taught throughout his life at a variety of Church programs such as VBS, Awana, St. Paul’s Sunday School, and Grace Kids.

Having grown up in the homeschool community, Nathan appreciates the opportunity to offer the same outstanding education that he received to the next generation. As a child, Nathan struggled to learn to read, so he understands the challenges of becoming a proficient reader and writer and aims to nurture the reader that exists in every student.

Involved in theater since a young age, Nathan has performed in over 50 different productions, including both semi-professional and professional jobs. During the last 6 years, he expanded his focus to include film, creating and producing a web series on YouTube called Project Jumpchute. Working on every aspect of this project, from writing to constructing sets to editing, Nathan learned what it takes to produce filmed content and what mistakes for beginners to avoid. He is thrilled to have the opportunity to share what he has learned about the process of creating films with future filmmakers.

Hi, my name is Helen Green (a local Christian artist) originally from Boerne, Texas.  I’ve been married almost 20 years to my faithful husband, Kelly Green.  We have a 14-year old daughter named Grace, plus a loud Sheepdog named Darla.

I love to paint and encourage others along the way. Let’s conquer the fear of messing up and start drawing and painting. My style is light and airy from impressionistic to contemporary, yet I have a variety of styles in between.

My background has been in retail advertising as Sr. Art Director/Grahic Designer for sixteen years, yet, my real art enthusiasm began by watching my mother paint on canvas, going to galleries and flipping through her art magazines. Now my own daughter loves to design & create, and we hope your loved ones will be inspired too.

The past ten years, Philippians 4:8 has been my prayer and hope for future artist, “Whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy – meditate on these things”.

I have sold my art through local stores, curators, Instagram, and a major national retailer.  As an artist, there is joy guiding numerous art camps from small artisan batches to church size events, afterschool programs, homeschool (mostly in my little home).  Once per year, I donate paintings to Scottish Rite Hospital for their Summer of Colors silent auction.

Looking forward to our time together and grateful.

I have been married to my husband Josh for 13 years. We have a 12 year old daughter, Kennedy, and a 4 year old son, Brandt. We also have two four-legged family members; Logan is our blue heeler/husky mix and Lyla is our chiweenie.

Through homeschooling my own children and being involved with co-ops, I’ve experienced an up-close view of how truly different we all learn. Experience is a great teacher, and God has equipped me with how to alter my teaching style when needed. I trust that He will continue to equip me and grow me as a THEO teacher.

I have learned to trust God’s plan and truly appreciate His sense of humor, mostly through all those times I said ‘I will never (fill in the blank here)’, and then those same things come to life.

It is such a blessing to have this opportunity to share my love of math with THEO students and help them gain confidence in a subject that isn’t always well-loved.

¡Hola! I am a native Spanish speaker, born and raised in Cuba. I am married and have three lovely girls. With the help of God, I have been able to home school all three. My two oldest graduated from THEO and are now in college. Through home education, I had the opportunity to pass on my native language to my daughters. Homeschooling them helped me discover a passion for teaching.

Outside of our home, my first experience teaching was under the direction and guidance of THEO’s presigious Spanish teacher, Shari Schwarz. She fanned the flame of my desire to impact the lives of home schooled students with the gift of a second language. I have enjoyed stepping in as a substitute teacher for many THEO classes, and I am excited to begin teaching my own classes this year. Alongside fellow THEO Spanish teacher, Julie Smith, I am in the process of becoming certified as a TPRS (Teaching Proficiency through Reading and Storytelling) Teacher, and cannot wait to work with your students. It is going to be a fantastic year!

Married to my faithful husband, Tim, since 1987. We met as public school teachers at Richardson Jr. High, but somehow always felt led to home school our own 6 children. We started the journey taking it one year at a time. I had no idea that I would home school for 26 years! That seems crazy, but it is something that we do not regret in any way! There is not enough space (even on the web) to write all the lessons I have learned raising and educating my children—every one of them unique with their own gifts and challenges which stretched me and showed me my own areas of growth in the Lord that needed to be addressed.

By the grace of God, five of our children are grown, married and serving in their own communities and churches. The baby is beginning college and we are looking forward to seeing where the Lord leads him in the coming years.

I have always had a teacher’s heart. There has not been a time in my life when I wasn’t teaching. God continues to bring opportunities to show His Love and His Hand in creation to others. I especially love teaching science to all ages. It seems the perfect place to let His light shine through me.

I am a retired homeschool mom who home educated my own children through high school.  I feel very grateful that I get to continue teaching homeschooled students here at THEO.

I have been teaching American Sign Language (ASL) at THEO since 2011 and I love it.  Before THEO, I co-taught ASL for four years with a Deaf friend at a local co-op.  The two of us also taught summer ASL classes at our church for five years.  These classes were so much fun and we sometimes had over 100 people in attendance!  I also served as the interpreter for the Deaf at my previous church for eight years.  I interpreted the worship service, Deaf Sunday school, and a weekly Deaf Bible study.  I continue to volunteer periodically for a Biblical counseling ministry and interpret for Deaf individuals who are being counseled and need an interpreter.

I am currently pursuing my BEI certification (Board for Evaluation of Interpreters) but have no plans to quit teaching.  I am still involved in the Deaf Community and I love introducing my students to this wonderful community, culture and language.  I get a tremendous thrill when students come to class excited to share with me about an interaction they had with a Deaf person at their church, on their job, etc.  I also love getting messages from previous students who meet Deaf people, often at their colleges, and they tell me they are so grateful for having learned to sign.

Many people are unaware of the fact that 98 percent of the Deaf are unsaved.  This is largely due to the fact that very few Christians are able to share the gospel with the Deaf in their language.  My prayer is that more and more believers will learn sign language, share the Good News with the Deaf, and those numbers can change for the better.

My name is Matthew Considine, and I will be co-teaching Worldviews here at THEO. As a former Worldviews student and THEO alumni (class of 2018), I understand just how useful Worldviews can be for higher education. I’ve found that it helps immensely in my ongoing college studies, and I’m excited to be able to give that gift of knowledge to my own students. I am currently an active member of Calvary Lutheran Church in Dallas, where I teach Sunday school and serve as Vice Chair of Youth Discipleship. I attend the University of Texas at Dallas, and I plan to pursue postgraduate education.
