Celebrating 20 Years of Plural Publishing!  

In 2004, Dr. Sadanand and Angie Singh launched their third publishing company dedicated to the fields of speech-language pathology, audiology, otolaryngology, voice and singing, and special education. The new company was the last in a number of successful ventures by Dr. Singh, who before beginning Plural Publishing founded the publishing imprints College-Hill Press (1980-1986) and Singular Publishing Group (1990-1999). While both companies were eventually sold, the Singhs' dedication to the field remained unwavering.  Recognizing an unmet need, they initiated a new company guided by the vision of partnering with notable authors to pioneer cutting-edge and high-quality resources designed to propel the disciplines forward in a transformative manner. The Singh’s debuted their new venture at the ASHA convention in Philadelphia that November.

"Oh, I get it! You were Singular and now you're Plural," was the common reaction from those familiar with the Singular imprint.

Plural’s goal has always been to elevate the science, comprehension, evaluation, and treatment of communication disorders to unprecedented heights, unlike any other publisher had pursued. Over these past 20 years, we have evolved from publishing a handful of titles to boasting a collection of more than 800 to date! Our texts are peer-reviewed by instructors and renowned experts to ensure their quality and suitability for the intended courses. 

Throughout Plural's journey, our primary objectives remain as we continue to advance the educational and intellectual standards of students, practitioners, and researchers, fostering a mutually beneficial environment for our customers, authors, and the company itself.  We invite you to join us in celebrating our milestone anniversary and stay posted as we have many special things planned throughout the year.
