The professors and guest speakers that MSTI features are the best in the industry. My private practice roster is filled with 80% of folks seeking sex therapy services. This education allowed me to distinguish myself amongst my peers and to continue to stay relevant in my practice and clinical care.

The material MSTI presents is highly relevant and presented by authors who have written widely in the field or have done academic research. I'm obtaining AASECT certification as well as being on the PhD track, and am excited with the possibility of reaching this milestone all from the comfort of my home! This couldn't be more convenient for working parents who need to support a family but also want to pursue graduate work. Were it not for MSTI, I probably wouldn't be able to achieve my goals of AASECT certification and attaining a PhD!

The Modern Sex Therapy Institute (MSTI) allowed me to add a new element to my psychotherapy practice. With the exceptional knowledge gained, I have transformed my practice into one that focuses on sexual-based disorder. In addition, MSTI 's structure allowed me to work while earning my Ph.D.

During my exploration of PhD degrees that involved in-depth training on sexology, I discovered Modern Sex Therapy Institutes surpassed all other programs. As a current PhD student, I now realize I made the correct decision. The program is very transparent on their expectations and is designed to cater to those who are working and/or have families. Most of the educators are internationally recognized as some of the best in their field. After each class I’ve gained knowledge that I’ve been able to incorporate immediately in my practice.

Having been fully immersed in MSTI’s PhD in Clinical Sexology for several months, I am even more excited than at inception about committing to this stellar program and the next step in my professional journey. The learning is cutting-edge, the instructors are engaging and well-versed in their area of expertise, and Rachel, Holly, and the entire staff at MSTI are extremely accessible and will gladly provide any assistance needed. And last but not least, I’ve met some amazing colleagues through the program!

It was such a relief to find MSTI while navigating my journey to becoming a Certified Sex Therapist. MSTI offers groundbreaking classes with phenomenal teachers. The customer service is top notch, and everyone is genuinely really nice. It's really cool to be in a space with like-minded people who want you to succeed.

I know of no other educational program that covers the vast array of aspects of sexology. Not only are you exposed to the many facets of sexology, but you will broaden the depth of your understanding of human sexuality, current and past. In addition, you will be exposed to professionals who are leaders in this specialized field, both psychologists and medical professionals. I believe there's no other PhD program that brings all of these elements together.

MSTI has put me in contact with professionals who not only focus on what I do, but offers a program where my full authentic self is valued in supervision.

Liberty Deffenbaugh

As an established clinician, I found myself floundering when it came to topics of sex, identity, gender, and orientation. Relying on my clinical skills and education left me wanting more. A colleague of mine referred me to Modern Sex Therapy Institutes in order to continue my growth trajectory. Having a family at home, work/life balance matters more than ever. The one-weekend-a-month scheduling allowed me to preserve my relationships with my family and also continue practicing full-time. 

Joshua Littleton

I knew I wanted to get my AASECT certification, but I felt utterly lost in the sea of requirements as I juggled working and caring for my family. I gave it a try and continually felt overwhelmed about whether I was taking the right classes and accruing the right hours. When I stumbled upon Modern Sex Therapy Institutes, I felt excited to put myself in their hands—the classes work with my schedule and take the guesswork out of the process. The classes appear on my account and in one weekend, I learn so much and complete my requirements!

If you are looking for an amazing Doctoral Program in Sexology, look no further than Modern Sex Therapy Institutes (MSTI). The education is top notch with a who’s who of elite educators like Emily Dr. Nagoski, Dr. Lori Brotto, Dr. Laurie Mintz, Dr. Stanley E. Althof, Dr. Nicole Prause, and Dr. James Wadley to name a few. Pricing is affordable especially compared to many other doctoral programs, and the coursework includes easy online access only one weekend a month. The administrative staff is easy to access and in tune, and I also appreciate the abundance of individual and group supervision. This program receives an A+ on every level, no kidding!
