The Founders

Avery Mann

Avery Mann (co-founder) has dedicated his career to the safety of children. At SOS ThreeSixty, Inc. Avery specializes in working with school leaders to implement necessary strategies to create the safest environment possible for children in their care. Avery brings his extensive knowledge of child safety and abuse prevention techniques to his work, building capacity within schools and partnering with school administration on revising and implementing more rigorous safety policies. Avery works with independent schools across the U.S. and Canada, regularly coaching senior leaders on how to implement important changes in their school that protect students.

Previously, working with federal, local and international law enforcement, he assisted in bringing hundreds of dangerous criminals to justice – many of whom were on the FBI’s ‘Ten Most Wanted’ list – during his 16 years with the original crime-fighting FOX TV program America’s Most Wanted. Avery also spent five years at the National Center for Missing & Exploited Children as VP, Communications, publicizing the work of the organization and leading the team responsible for safety education.

Before founding SOS ThreeSixty, Inc., Avery was part of the senior team at the Bellevue (WA) School District.

He’s also the host of Making The Case: Crimes Against Kids – a podcast that interviews crime survivors, advocates and law enforcement – and provides listeners with important tips on how to keep children safer.

As a life-long advocate for child safety and justice, Avery received the U.S. Attorney General’s Meritorious Service Award and graduated with a Master of Science degree with honors, in Justice, Law and Society from The American University and a Bachelor of Arts in Politics and Criminology from Simon Fraser University.

“A child grows and thrives best in a secure environment. Since safety begins from the inside, we offer ‘Boundary Training’ for all staff – and sensible ‘Interviewing Training’ – so that schools and camps establish and maintain the most ethical and safest space for children.”

Nicole Mann

Nicole works with independent schools across the U.S. and Canada and co-created the first and only online, asynchronous Boundary Training and Abuse Prevention program specifically for independent schools, in partnership with child safety experts and independent school leaders. A survivor of educator misconduct as a child, she deeply understands the complexities and impact that the experience and subsequent investigation and prosecution have on a young student, their family, the school and the broader community.

Nicole began her career working with LGBTQ+ inner-city youth in the 90s during the HIV/AIDs crisis, creating social programs and safe spaces to belong and to have fun. She went on to develop health advocacy programs for Indigenous youth in Mexico.

Detective Robert Shilling – a 37 year veteran of the Seattle Police Dept. – was recruited to be the Head of Crimes Against Children at INTERPOL Headquarters in Lyon, France, starting in 2013. He served there for three years and was responsible for the International Child Sexual Exploitation database (ICSE) which contains child abuse images from all over the world. These images are submitted by INTERPOL member countries.

Det. Shilling’s team and network of investigators were responsible for identifying and rescuing the previously unknown victims shown in the images. By the end of his three-year secondment, Det. Shilling’s team and network of investigators had identified and physically rescued 5,420 victims of sexual abuse from “images” in the ICSE database. This was more victims rescued in three years than had been rescued in the previous 13 years combined.

Prior to this posting – and during his full time duties with the Seattle Police – Det. Shilling was appointed by the INTERPOL Secretary General to the INTERPOL Specialists Group on Crimes Against Children. During his thirteen-year tenure, Det. Shilling Chaired the Major Crimes Against Children, and the Sex Offender Management theme groups. In 2009, Det. Shilling was elected as the Chair of the Specialists Group by the INTERPOL member countries.

Det. Shilling also served for seven years as a voting member of the Washington State End of Sentence Review Committee. He served as an Advisory Board Member of the Twin Rivers Sex Offender Treatment Program and the Washington State Special Commitment Center. He served for five years as a Board Member of the Association for the Treatment of Sexual Abusers (ATSA) and he is an ATSA Fellow.

Det. Shilling was the recipient of the 2014 International Council of Jurists Award presented in London by the President of the International Court, and the former Prime Minister of Jordan. The award was for his lifetime achievements in protecting the rights of children. Det. Shilling was the first law enforcement officer to ever receive this award.

In 2015, Det. Shilling was honored at Facebook Headquarters in Dublin, Ireland with the “Wired Cop” Award for his lifetime achievements in protecting children online. In October 2017, Det. Shilling received the “Distinguished Contribution Award” from the Association for the Treatment of Sexual Abusers for his “notable contributions to the field of sexual abuse.”

Det. Shilling has spoken at conferences all over the world on sexual abuse and sex offender management, including Tehran, Iran; Moscow, Russia; Bucharest, Romania; Doha, Qatar; Manila, Philippines; Bangkok, Thailand; Tashkent, Uzbekistan; Jilhava, Czech Republic and Abu Dhabi, UAE.

Earlier in his career, retired Det. Shilling spent 10 years as a Seattle patrol officer. He also served for three years as President of the Seattle Police Officers Guild and five years as President of the Washington State Council of Police and Sheriffs. Det. Shilling was known as a problem solver and someone who could work with both sides of an issue ultimately “getting to yes.” He received many commendations and professional recognitions for his work from citizens, as well as city, state and national leaders.

Det. Shilling spent twenty-six years in the Detective Bureau where he was assigned to the Sexual Assault and Child Abuse Unit. He investigated hundreds of cases of sexual abuse against children and adults. Det. Shilling had a reputation for being a fair, compassionate, thorough and successful investigator who left no stone unturned. He spent 18 of the 26 years as the Lead Detective in the Sex and Kidnapping Offender Detail which is responsible for sex offender address verification, risk assessment, community notification and public education meetings.

Det. Shilling taught community transition classes for sex offenders who were at the end of their sentence and housed in the sex offender treatment program at Twin Rivers Correctional Center in Monroe, Washington. He spent many hours at the treatment program working with offenders and staff to understand how sex offenders groom victims, and how they are able to maintain a veil of secrecy in furtherance of their abusive behaviors.

In 1993, Det. Shilling developed a curriculum for doing community notification – public education meetings. This curriculum was seen by many as a nationwide model, and it assisted many law enforcement agencies across the United States in conducting these meetings without violence or vigilantism. The meetings were truthful, informative, and very popular with citizens. The U.S. Department of Justice and the Center for Sex Offender Management subsequently contracted with Det. Shilling to train law enforcement officers on this curriculum in over 20 states. He has also provided training in Australia, France, Spain, the UK and Switzerland.

Detective Shilling has authored or co-authored twelve pieces of legislation that have been passed into law, most of them having to do with sex offender management. He has testified before legislatures in several states, and twice before the U.S. Congress, on matters relating to sexual assault and managing sex offenders in the community. Himself a survivor of horrible childhood sexual abuse, Det. Shilling has been a passionate and inspirational advocate in the fight to combat sexual abuse.
