About My Approach

I help people become better. In philosophy, this falls into the domain of ethics, which asks “How should we live?” and “What is good?” But philosophy originally was a practical discipline, not merely abstract reasoning. In Greek “philo-” means love and “sophia” means wisdom. Wisdom comes from experience, especially that of trying to deeply understand one’s life and the world and how to best live in it.

Sometimes we experience knowing the right thing to do and not being able to do it.
At other times we know we are doing the wrong things but don’t know how to stop.
And there are also times where we don’t know what to do at all!

These problems have been around a long time. Aristotle called it “akrasia.” But Aristotle didn’t have the know-how of personal change we have today.

With the right strategies, and persistent effort over time, we can find ways to automatically do the right things, and avoid doing the wrong things. People working in the practical discipline of Neurolinguistic Programming (NLP) have created a rich source of techniques for helping people to make these kinds of positive changes. (And as with all psychological tools, some people have used these powers for evil.)

I’m interested not only in what is the right thing to do, but also how do we get ourselves to do it, and with as little pain and suffering as necessary. What I love about NLP is that the tools I use to help people change do not require painful catharsis. Change occurs not through revisiting and expressing painful emotions but by increasing one’s ability to act effectively and imaginatively in challenging situations. In fact, many NLP techniques can be done entirely without sharing any details of the problem at all. And sometimes (but not always), NLP methods can lead to changes that are faster than anyone thought possible.

So what I do is educate people on how they work, how they are using their brains in ways that cause their problems, and how to do something else instead that is more useful. Once a person learns that, they have the keys to the changes they want.

When we know how to do good effectively, we can make the world a better place, starting with ourselves.

About Me

Duff McDuffee headshot


I’ve been coaching clients all around the world to make significant positive changes since 2003. My style is solutions-focused and consultative, getting specific about the outcome you want and using the tools of Neurolinguistic Programming (NLP) to find the fastest, most elegant way to make it happen. I currently work for two founders of NLP, Steve and Connirae Andreas, and use many of their techniques with clients and with myself including the very powerful “spiritual” NLP process Core Transformation.

I have taught Introduction to Ericksonian Hypnotherapy and Introduction to NLP with the Denver School of Hypnotherapy, have assisted as a coach on numerous Core Transformation trainings with Tamara Andreas, have trained in Andrew T. Austin’s excellent Metaphors of Movement model, and attended other advanced NLP trainings in addition to many years dedicated to studying and applying NLP in my personal life.

I also train people in NLP with the iNLP Center.


I received my undergraduate degree from Lawrence University, a small liberal arts college and conservatory of music often called “the Ivy League of the Midwest.” I graduated with a degree in Philosophy, studying primarily ethics, psychology, cognitive science, and environmental science, while also participating in several ensembles and even dabbling in some improv theater.

Dissatisfied with academic philosophy and studying the mind from the outside, I discovered NLP in 2002. Having engaged in personal development and change since an early age due to personal limitations, I found NLP to be the first set of tools that really helped make a big difference in my thoughts, feelings, and behaviors, as well as my communication skills. The technique of Core Transformation specifically made a huge difference for me over the course of several hundred practice sessions.

I have also practiced Vipassana meditation in the style of S.N. Goenka’s 10-day courses, spent several years doing “friday night dance therapy,” and enjoy exercising a variety of ways from yoga to clubbells and StrongLifts 5×5.
