About Us
Donna Brewer Kassewitz

Donna works with her husband Jack in the Research Project, advancing the field of human-cetacean communication in order to give dolphins and whales a greater voice in world affairs. In 2006, she created the Clean Ocean Dolphin Poster campaign, which encourages the public to help clean up our oceans and waterways.

As part of her research into cooperative games with dolphins, and in order to create a Peace Ceremony for the Oceans, each summer Donna and her daughter, Noel, use a waterproof Earth Flag with the printed phrase "May Peace Prevail On Earth", and custom-made waterproof ribbons (from their own innovative Dolphin Ribbon Game) for an underwater parade with the dolphins at Dolphin Discovery's facilities in Isla Mujeres and Cozumel, Mexico. The response from the dolphins has been remarkable! Each year, Donna and Noel are engulfed in dolphin echolocation as the animals excitedly "buzz" the Earth flag. The human swimmers parade the Earth flag throughout the large dolphin lagoons while saying Peace Prayers through their snorkels and dive regulators. In each event, the dolphins participate by exuberantly following along, often surrounding them on all sides. From the enthusiastic and willing participation of the dolphins (no food rewards or trained behaviors used), it certainly appears that they are interested in the image of the Earth from space, as well as the intent for Peace On Earth. Donna and Noel eagerly look forward to further Peace events and cooperative games with the dolphins.

Born in Miami, Donna developed a close relationship to Spirit during childhood. She has extensive experience bringing people and dolphins together. Donna has facilitated numerous spiritual retreats in the Yucatan, leading groups there to swim with dolphins and explore Mayan archeological sites. In 1995 and 1996, she organized and co-hosted two International Symposiums on Dolphin-Assisted Therapy in Cancun, Mexico.

Donna and her husband, Jack, have facilitated many community events in South Florida, through their non-profit organization, Global Heart, Inc. Donna and Jack are Official Representatives of the World Peace Prayer Society (, and have planted eight Peace Poles in Florida, Georgia, and Mexico since 2001.

In each project that she manages, Donna brings her organization skills, writing talents, artistic abilities, and visionary passion as her tools of trade.  Donna is an inspiring teacher and speaker, with personal stories of struggle and transformation, and a deep belief in the power of prayer and positive thinking. She avidly promotes the importance of Human-Cetacean interaction as a means to safe-guard the ecology of our Planet.

Jack Kassewitz

Jack Kassewitz is President of Global Heart, Inc., a non-profit organization that he co-founded with his wife, Donna, in 2001. His greatest focus at this time is Global Heart's - Dolphin Communication Research Project - seeking to significantly expand communication between humans and dolphins.  Jack's passion for this research has propelled him to search out and obtain cutting-edge technology for recording cetaceans in the broadest spectrum and highest definition possible.

A lifelong percussionist, Jack's musical skills led him to the first breakthrough in his research - the discovery of complex musical form within dolphin vocalizations. Although the songs within these dolphin vocalizations are too complex for the human ear in their original form, Jack used graduate level musical students from the University of Miami, to perform the dolphin songs on human instruments such as guitar and piano. This allows humans to appreciate the beauty and sophistication of the dolphin composed music.

Recently, Jack's work on the Castaway & Calf Project broke new ground in the field of dolphin communication research. Jack is currently analyzing his recordings of Wilson, Castaway's baby, whom Jack was able to record echolocating even as the baby dolphin was emerging from the womb.

Jack Kassewitz was born in rural Georgia in 1947 and moved to Miami as a young boy. He has worked for much of his life in the care giving field. He was Principal of a school for emotionally disturbed children, directed a state licensed drug rehabilitation center, was the Director of the Humane Society facility in Espanola, New Mexico, and was also a Director for the United Way of Dade County.

Additionally, Jack founded the National Wildlife Rescue Team that rehabilitated and released many hawks, eagles, owls, bears and other wild animals. Jack was also an Investigative Reporter and Independent Producer of several television news specials, including segments on NBC News Dateline and ABC Primetime Live.
