This book is dedicated to my wife, Shilpa, and our three children, Raj, Viren, and baby Neeva, who have all supported me on this adventure to add value to the lives of those who suffer from disability.

Additionally, I have a tremendous amount of gratitude for all of the mentors, colleagues, and learners who I have worked with throughout my career, and especially my parents for their early encouragement and exposure to science.

Finally, I would like to thank the hundreds of contributors to this book and the thousands of fellow health care professionals and students who selflessly dedicate their time toward the betterment and empowerment of the disabled population worldwide; may they never, never, never give up!
