In law enforcement, individuals are often promoted to supervisory positions before receiving training to serve in those positions effectively. This has ended in catastrophic failure or the proverbial sink-or-swim situation for many first-line supervisors. These first-line leadership failures can have a high price tag for law enforcement agencies. Readers of The MASCOT LEADER will find foundational success principles in their agency's mission, values, policies, and procedures, such as their Field Training Manuals. Using the MASCOT mnemonic, the reader will embark on visible and memorable perspectives of these usable principles. The MASCOT Leadership model is a valuable resource for officers seeking to become first-line supervisors or those already in the role but needing to heighten their leadership acumen. Moreover, there is a theme throughout the book stressing the officers' need to recognize that they are direct representatives, like a MASCOT, of their organization when in uniform. William G. Thompson Jr., also known as Jerry, is a retired law enforcement veteran who worked for the Ohio State Highway Patrol for 31 years. He began as a cadet dispatcher and advanced to become the Northeast Ohio LCS Unit Commander. Jerry's qualifications include Ohio Peace Officers Training Instructor, a Bachelor of Science in Human Resource Management, a Master of Science in Organizational Leadership, and a Northwestern University Staff and Command School graduate. Jerry is an instructor with FBI-LEEDA, providing instruction in Supervisor and Command Leadership concepts. He was raised by devout Christian parents who instilled values that have been key to his success in life and within every organization he has served. Jerry strongly believes every law enforcement officer needs to recognize that they are a direct reflection of their organization - a MASCOT.
