Nicholas "Nick" Groff (born April 19, 1980) is a co-investigator and executive producer of Ghost Adventures, as well as an editor and cameraman for the show. He is a co-founder of GAC, the Ghost Adventures Crew. Groff was Executive Producer for a show on the Travel Channel called Vegas Stripped, a behind-the-scenes look at the operations of the South Point Hotel, Casino & Spa in Las Vegas, NV.

Born in San Jose, California, Groff grew up in New England. He graduated from Pelham High School and later studied film at the University of Nevada, Las Vegas, where he met Aaron Goodwin. After graduation, his interest in the paranormal led him to become a ghost hunter. His fascination in the field, however, began much earlier in life. At the age of eight he fell out of a tree in the yard of his family's home in Salem, New Hampshire. Groff describes it as "a near-death experience," though he underwent none of the events traditionally associated with a near-death experience, such as seeing deceased relatives or being drawn toward a tunnel of light. Two years later, while at home alone, he saw a ghostly black figure. In a 2012 interview, Groff said he wondered: "Was it my imagination? Or was it something from my accident that made me more open to that world?"^[11]

After Groff met and befriended Bagans during Groff's wedding in Las Vegas, the two joined forces.^[12][13]

One of Groff's most life-changing experiences was apparently being possessed by an entity at the Moon River Brewing Company in Savannah, Georgia.^[14] A similarly startling experience was a face-to-face encounter with a female spirit at the Linda Vista Community Hospital in East Los Angeles, California. This encounter gave Groff insight into what he had been searching for: life after death in this world. Groff uses the term "Energy Doesn't Die," and is still searching every day for that next experience that will bring him closer to the other side.

Groff released a music CD entitled The Other Side. He wrote, produced and sang all the tracks. The lyrics recall Groff's spiritual journey.^[15]

As of 2012, he and his wife Veronique reside in New Hampshire and Massachusetts with their daughter, Annabelle.^[15]

Zachary Alexander (Zak) Bagans (born on April 5, 1977) is the lead investigator and co-founder of the Ghost Adventures Crew organization, one of the largest worldwide network of professional paranormal investigators. Zak was born in Washington, D.C. and currently lives in Las Vegas, NV.

As a former skeptic, Zak says that his passion for investigating the paranormal resulted from a face-to-face encounter with the spirit of a suicidal woman in his apartment building in Trenton, MI, in 2002. He graduated from film school in MI.

Zak is known, and sometimes criticized for his aggressive and confrontational methods used during investigations; however, he maintains that he respects the afterlife and only provokes evil entities in order to elicit responses.

Zak has hosted and produced the “Ghost Adventures” series since the very beginning in 2008. In 2011, he hosted and produced the show “Paranormal Challenge” on the Travel Channel. Zak also narrated the Travel Channel special “Ultimate Travel: Legends of the Parks”, about paranormal activity in national parks.

Zak wrote a book with Kelly Crigger titled “Dark World: Into the Shadows with the Lead Investigator of the Ghost Adventures Crew”. The book debuted at number 18 on the New York Times Best Seller list on September 23, 2011.

2012 remains a busy year for Zak: he continues hosting and producing the “Ghost Adventures” Series (currently on Season 7); he launched his private clothes line called “DungeonWear” on Aug. 18; has been in two music collaborations, one within the new Lords of Acid album “Deep Chills” with a song called “Paranormal Energy” and the other with Praga Khan with the full length album entitled “Necrofusion”, set to be released on October 23; and is the Executive Producer of a new show on the Travel Channel, “Paranormal Paparazzi”, which premiered on September 28, 2012.

Andrea Rosanoff, Ph.D. is Director of Research & Science Information Outreach for the Center.

In 1982, Andrea Rosanoff received her Ph.D. degree in Nutrition from the University of California at Berkeley. 

In 1985, Dr. Andrea Rosanoff was invited to give a short commentary upon an environmental technology proposal that included magnesium.  To prepare, she went to the library to learn what she could about magnesium and was surprised to find research that linked nutritional magnesium both clinically and in population studies to heart disease -- the largest killer in her country, the United States.  These were links she had not learned about during her graduate education which specialized in the nutritional minerals.  Her interest piqued, Dr. Rosanoff kept reading about magnesium every chance she got at her jobs as Senior Chemical Information Specialist at Dialog Information Services and as Information Analyst at Chevron Research & Technology Corporation.  At both jobs she became adept at online searching of the peer reviewed scientific literature, a skill which serves her well today as an Independent Scholar  with expertise in Nutritional Magnesium.

By the late 1990’s, Dr. Rosanoff ‘s “hobby” evolved into co-authorship  with Dr. Mildred Seelig in the writing of “The Magnesium Factor”, a book on magnesium and heart disease, and from there to original research and publication in scientific journals.   In 2005, Dr. Rosanoff formed the Center for Magnesium Education & Research, LLC.  The center conducts research into all aspects of nutritional magnesium and attempts to inform the world of their findings.

Keith Amber began his spiritual path at the age of nine with the realization that he was winning almost every game he played by running over the competition with the use of his willpower. He stopped this behavior and started helping the underdog instead. In an attempt to figure out many of life's mysteries, he disciplined himself to read the Bible for a minimum of one hour per day during his three years in high school. After two years of college, at the age of 22, he left to train and work as a massage therapist and quickly became the manager of one of the largest health spas in Reno, Nevada. During this time, his spiritual gifts as a healer began to emerge. Ardently, he studied self-realization, Black Elk healing, and meditation.

After several years, Keith stopped working as a massage therapist and began a full time practice as a Spiritual Healer-Reader, Offering Sound Answers to Life's Tough Questions. He has worked with thousands of clients, helping them to understand the lessons they are learning on their path. This work exposed Keith to volumes of fascinating information about the inner workings of our lives and lessons and how to transform our daily lives and our souls.
