Leon Cerna, SPHR | President
Leon Cerna is a highly-skilled human resources professional with 20 years of experience in strategic management, employee relations, talent acquisitions, and training and development.
Leon’s interest in human resources was sparked by his childhood involvement with his family’s growing business where he learned the key elements of hiring, training, and effective conflict resolution from his parents.
These experiences taught Leon that the keys to creating a workplace that fosters employee engagement are effective management techniques and the ability to communicate a clear vision of future success. Leon instinctively understood these lessons and knew a career in human resources would offer the ideal platform for his developing interest.
Leon has held leadership roles in Fortune 15 and 300 companies and served in the public sector as a Chief HR Executive. He has provided strategic oversight of human resources departments and established foundations of respect, diplomacy, high ethical standards, and collaboration that have promoted the overall success of the organizations.
His exceptional skills have been sought after by a variety of councils, commissions, and committees including most recently the Personnel Merit Commission for the City and County of Broomfield. Leon’s philanthropic interests include mentoring and coaching recent college graduates who are entering the workforce.
Leon received his Bachelor of Science degree in Labor Relations Management from the University of the Pacific in northern California. He has a Senior Professional in Human Resources (SPHR) designation and maintains an Advanced Certificate in Employee Relations Law from the Institute of Applied Management & Law.
Originally from Southern California, Leon now lives in Colorado and outside of work, enjoys spending time with his family, his dog, listening to jazz music, and playing golf where he carries a five handicap.
