Dennis R Sumlin, Coach, Speaker, and Trainer

Passionate promoter of positive change

Hello. My name is Dennis R Sumlin, and I am a promoter of positive change. As a Coach, Trainer and Speaker, I specialize in confidence building and healthy self-esteem. My services help my clients get past fear and develop their public and interpersonal communication skills, develop a healthier relationship with self and others, and staying the course towards their goals.

I have worked with, and been a consultant to young entrepreneurs and professionals, as well as given talks, mentoring and trainings at many educational institutions such as The City College Of New York, and The Door (NYC), , Civil Rights organizations such as The National Federation of the Blind (NFB), and inner city communities.

Along with 15 years of teaching and performing, I have a Distinguished Toastmaster (DTM) certification from Toastmasters International (Speaking and Leadership) as well as a Life Coach certification from Erickson College International.

As somebody who grew up without a strong male role model, and somebody with a disability, I understand the importance of a solid sense of self-confidence. I want to provide other men with what I did not have. I am able to use my inner struggles and lessens, along with my knowledge of men’s personal development to help you see solutions.

Speaking came natural to me, and I want others to use this all important skill to attract the right people, crush anxiety, and get what you want. I love working with self-starting, ambitious people. With me, you get a straight forward, fun, experienced coach that brings out the person inside you so you can see it and live it. If you want to live as the highest version of you, take the plunge!
