Professional Laughter Experts, Coming Together for a Greater Good

The World Laughter Tour professional advisory committee is comprised of distinguished experts from all walks of life. From authors, humorists and psychologists; to counselors, professors, hypnotherapists and scientists, these experts take the matter of laughter very seriously (no pun intended)! Their role is to advise and guide the initiatives of WLT, while validating scientific studies and research as to how laughter affects the physical, mental, social and spiritual well-being of the participants.

This outstanding volunteer group has been an enormous help in shaping our curriculum. They make themselves available to answer questions and offer support in the day-to-day practices of the Certified Laughter Leaders. They play a key role in our outstanding reputation.

Our goals are in alignment with the core mission and principles of the Good-Hearted Living™ program. By coming together to discuss new methods of delivering awareness about the benefits of laughter as it relates to the human mind and body, we are able to achieve more through a unified approach. Meet the current principals of the Professional Advisory Committee below to learn more about their qualifications.

rajiv-and-cartoonRajiv Samant MD, FRCPC, DABR
Rajiv is a radiation oncologist at The Ottawa Hospital and an Associate Professor in the Faculty of Medicine at the University of Ottawa. He has been caring for cancer patients for over 25 years, and has gained much wisdom from his patients and colleagues during that time. As a teacher, educator and researcher interested in improving how we deal and communicate with patients and their families, he believes patients need to be treated on an individual basis with dignity, respect and kindness as well as with a good dose of humor where circumstances allow for levity to enter a too often serious world.

Many people view cancer as all doom and gloom and think that his job must be very serious, sad and depressing all the time. However, there is much more humor and positivity when dealing with cancer patients than you might think. In fact, since cancer will affect almost half of all North Americans, it might be beneficial to deal with it in a positive way! He has decided to show people that working with cancer patients can be filled with laughter and smiles. This is why he published his book titled “Smiles from the Clinic: A humorous look at cancer” and wants to share with everyone the true, funny stories and experiences that he has witnessed in his day-to-day work. His prescription for everyone, including those with cancer and those without it, is a daily dose of smiles and humor – and you don’t need to go to the pharmacy to get this since is all around you!
