Meet The Team


Cally Walker

Founder & Executive Director

Cally is a strong believer in “putting back” into the world what is taken out. She loves adventure and travel which makes the perfect fit through Dental Mavericks. More importantly she is the mother of two gorgeous twins, Billy and Tallulah.

Cally believes in a strong work ethic coupled with determination and stamina which she brings to her work and projects with Dental Mavericks. A former Girl Guide & Brownies Leader, Cally supports local charities each year.

Her role in Dental Mavericks often takes her to Morocco and Lebanon where she empowers ground teams in each country to drive the work forward and meet the emergency needs of impoverished communities with vital dental treatments and oral hygiene programmes.

Her passion is in research so that we can make every penny count and be able to improve the health and oral hygiene of beneficiaries who come under the Dental Mavericks’ team.


Richard Howarth


Dentist Richard Howarth qualified from Turner Dental Hospital, which is part of the University of Manchester.

Richard loves the precise nature of dentistry and the challenge of trying to achieve perfection while his great communication skills and ability to build rapport have given many anxious patients the personal and emotional support that has allowed them to receive dental care.

Richard said, “We know how to cure tooth and gum disease and it is my aim to help as many people as possible choose dental health for life.”

Richard is active both in his community, nationally and internationally promoting dental health.

She has held a variety of jobs including working in the buying department of Emporio Armani, radio presenter, filming and editing commercials teaching English as a second language and head of education in a zoo.

“As a single mother of two amazing girls, having this chance to expose them to new and wonderful cultures is really important to me. The opportunity to work for Dental Mavericks is so exciting, it combines my love of travel, and being of some help to a lot of children, it’s unique and very fulfilling.
“None of this would be possible without the amazing leadership and training by Cally and the support of all the volunteers, abroad and in situ.”
