Testimonies & Endorsements

We are extremely thankful to all of those of the years that have taken part of countless programs, courses and outreaches hosted by International Defensive Training Systems (IDTS) over the years.


We truly believe this is only the beginning of a long, hard battle to end human and sex trafficking. However, one community at a time and together we can do this!

“..I am so thankful for Marilyn, all the volunteers, and this organization for helping my children and I with the possibilities that could happen instead of naively thinking if we do good, bad won't happen.. My children and I all took a course with IDTS.. and we learned how, in certain situations, to protect ourselves from becoming victims. I can not express my thankfulness for all the work they are doing. For so many girls, women, and families. I pray God will bless this company for their hearts to protect and defend against the evil that is so prevalent in our world.”

" This was by far the best education and hands-on education class I have ever come across. I was amazed at how the instructor taught each girl how to get away from a stranger in all different kinds of scenarios."
Nicole C.
A Mother
“I liked how the boys learned how to be aware of their surroundings and all the different approaches on how someone could try and take them and how to get away, which they will never forget. I was amazed at how Marilyn and her staff made the boys feel comfortable before, during and even after the class. They gave them confidence I have never seen before. I think this class really opened the boy's eyes and prepared them for the unknown. I would recommend this class to everyone who has kids! The more our kids are aware and prepared the better chance they have of surviving! Again, Thanks for the class.”

"I am so impressed with the moves, so technical yet so simple. I've had training in martial arts but this is so great to see move's that are so easily taught to people."

“Thank you for coming to my school and teaching my girl scouts all about your Anti-Abduction program..The girls were a little scared at first.. but became pros by the end of the class with tons of newfound confidence. This was all because of the knowledge you provided to my girls. The knowledge that sticks with them because of the way the class was conducted. My daughter talks about how awesome it was all the time and how much fun it was! They loved it! So cool, Thanks again!! “

The Phoenix Dream Center

“The training by International Defensive Training was tremendously powerful for our Team.  The training was thorough, informative, and provided great insight for all of my team of staff and outreach workers, and persons who conduct work in our facility on the streets and in somewhat risky situations.  

The preventative, post victimization systems, and the 6 point de-escalation system are all powerful tools for Homeless, Domestic Violence, and Sex Trafficking Rescue Projects. I highly recommend this training for any organization and or company that has a rescue project, outreach workers or persons who are in the field”.

“I am proud to work with International Defensive Training Systems, and I hope you will all join me in the fight against Domestic Minor Sex Trafficking (DMST), Domestic Violence, Sexual Assaults, and Abduction.”

TEN40 Church

“This year IDTS, led by Marilyn Parker, trained Arizona State University Students who attend TEN40 Church on how to be aware of, and defend against, sexual predators. The training prepared both female and male students how to detect potential sexual predatory actions as well as how to defend against a direct attack.

After completing the training, the TEN40 Church students then partnered with the Pat Tillman Veterans Center at Arizona State University to host a class to teach other students what they’ve learned. The results have been amazing! Subsequently, the classes have created a path to healing for students who have been previously affected by sexual predatory actions.

I would highly recommend Marilyn Parker and IDTS as a resource to any church or social organization who is serious about awareness and prevention of one of the most serious issues plaguing our community and world today.

Certified Trainer Testimonies

"IDTS. Going through this journey as a survivor and seeing all your heart, passion, the laughs. I truly was blessed to be able to be a part of this. Marilyn Parker, you are such an amazing woman and I pray God blesses IDTS to the fullest.. I pray for many blessings over IDTS"

"Marilyn Parker the founder and CEO of International Defensive Training Systems (IDTS) has stepped into that chasm with passion and intensity to see young women protect themselves against those who would try and take advantage of them. Marilyn and her team of trainers trained our team to teach the techniques of self-defense to young women on our campus. I have over 20 years of experience in military and police training which includes many hours of pressure point control tactics and hand to hand combat and I am highly satisfied with the techniques used to train these young women. However, the physical training which is superb is just a small portion of what I am pleased with. The way the training is developed lends to such a transformation of self that it is undeniable. There is empowerment and worth that wells up in these ladies as they go through the course. So many of the young women find their own voice for the first time."

"The past several weeks have taught me so much about what I am capable of. I used to wonder what I'd do if I was ever in a terrible situation that I see on TV, at the same time as thinking it could never happen to me. After learning that one of the women I trained with had survived such a terrifying reality, it made me realize that the issue is closer to me than I ever thought, even after all my research.. Thank you, Marilyn, for creating IDTS and for working so hard to make sure that the women and children of this nation are safer. I feel so blessed to be part of your movement and I cannot wait to see where God takes us."
Alana C.

"For the last few weeks, I have been participating in a self-defense class..7 weeks in and with 1 more week to go, I can't be happier to have been a part of this awesome experience. This training will help protect these college students from the growing problem of sex trafficking and rape. I couldn't be more excited to be on this journey and know that what I am doing can really help make a difference."
Jeffery K.
Certified IDTS Trainer
"Over the past 6 weeks, our team had the pleasure of training a group of young women which consisted of ASU girls and a group of rescued women who have survived the horror of sex trafficking. I watched and praised God for how he loves these women and how He is using us through IDTS to heal broken hearts and help them find their worth again. Through IDTS, we don’t just talk about the problem, we do something to fix it. And with God’s help, we will continue on as we are obligated to help those in need. I wholeheartedly recommend you find the time to connect with Marilyn and IDTS to see how you can become certified and be a driving force with them to abolish this new form of slavery which dwarfs all other forms before."
