Core Confidence Life is an education and talent promotion service that assists holistic, independent minded individuals in developing a positive self-image and effective communication/speaking skills. We work with authors, artists, public figures and the average person to strengthen natural abilities and develop and promote their core message.

We believe that everybody has a purpose and a wealth of wisdom to teach, and we are here to help you do just that. Our School Of Personal Development contains courses around public speaking, mindfulness/self-confidence and related topics, while our promotion department contains the CCL Podcast as well as other podcasts and programs to post your product or service to a cross section of people.

Founded in New York City in 2014 by Dennis R Sumlin, a certified Life Coach and teacher, Core Confidence Life is a place of higher consciousness, lower stress, and sharper skills. Our mission for our clients as well as the community at large is to break down old stigmas, recognize personal power, and own the present and the future.

We got your back

It saddens me to see people who lack confidence, who do not see their talents, and think they are ugly, when in fact, they are beautiful. It is my mission to show people that mirror, walk with them, then tell the world about them!

We understand that a person is made up of mind, body, and spirit, and we promote that message and the method.

People we have worked with

We work with individual clients as well as conduct in person and online classes. We also work with other schools and education centers to bring our expertise to their students.

Some of our individual clients have been public office candidates, fortune 100 employees, working class immigrants, and public school teachers.

Educational institutions such as The Door (New York), International Christian University, and The City College of New York have been some of our clients as well.

Our promotion department has interviewed and assisted singers, actors, entrepreneurs and other public figures.
