The Tuscola County Sheriff’s Department is shuffling its leadership deck with three significant personnel moves that Sheriff Ryan Robinson says reflect the continued development of leadership within the agency. The promotions and assignment changes, all taking effect February 14th, come as the department transitions following the retirement of Lieutenant Ted Hull, creating opportunities for experienced officers to step into expanded roles.
These aren’t random promotions handed out to fill empty slots—these are carefully considered moves recognizing officers who’ve proven themselves through years of service, specialized training, and dedication to the department and Tuscola County residents. When you look at the combined experience these three officers bring to their new positions, you’re talking about decades of institutional knowledge and expertise moving into leadership roles where it can shape department operations and culture.
Detective Sergeant Timothy Zube is transferring to the Detective Division, bringing a skill set that should serve investigations well. Throughout his career, Zube has accumulated specialized roles that read like a resume built specifically for detective work. He’s a certified accident reconstructionist, meaning he can analyze crash scenes and determine exactly what happened based on physical evidence, skid marks, vehicle damage, and physics. That expertise translates directly to investigating serious crashes and potentially to other crime scene analysis work.
Zube’s also a certified drone operator, which is increasingly valuable for law enforcement. Drones provide aerial perspectives on crime scenes, assist in searches for missing persons, document accident scenes from angles impossible with ground-based photography, and support tactical operations. Having that capability within the Detective Division expands investigative options and provides modern tools that would have been science fiction just a couple decades ago.
His experience as a Field Training Officer demonstrates leadership skills and the ability to pass knowledge to newer officers. FTOs shape how departments operate by training the next generation of law enforcement, establishing standards for professionalism, and instilling departmental culture in new hires. Those training and mentoring skills will serve Zube well in the Detective Division where investigators often work collaboratively on complex cases.
Spencer Coleman is being promoted to Sergeant within the Road Patrol Division, recognizing a career trajectory that started in corrections and progressed through increasingly responsible positions. Coleman began with the department in 2013 as a Corrections Officer—working the jail where he learned how to manage difficult people, maintain security, and handle the stress of corrections work that often gets overlooked when people think about law enforcement.
He transitioned to Road Patrol in 2015, making the move from the controlled environment of a jail to the unpredictability of street patrol where every call could be routine or life-threatening. That’s a significant transition requiring different skills, different mindset, and adaptability to rapidly changing situations.
In 2022, Coleman became a K-9 Handler alongside his partner Belo. K-9 units represent specialized law enforcement requiring extensive training not just for the dog but for the handler learning to work with and manage a highly trained animal. K-9s assist with drug detection, tracking suspects or missing persons, building searches, and sometimes apprehension of dangerous individuals. Coleman’s experience managing a K-9 program demonstrates responsibility and specialized expertise beyond standard patrol work.
He’s also served as a Field Training Officer, again showing leadership capability and the trust the department places in him to shape new officers. Now as Sergeant, Coleman moves into formal supervisory roles where he’ll be responsible for overseeing other deputies, managing shift operations, making tactical decisions, and representing the department to the public during critical incidents.
Joshua Herman’s promotion to Lieutenant within the Road Patrol Division fills the gap left by Lieutenant Hull’s retirement. Herman brings the longest tenure of the three officers being recognized—he started with the department way back in 2002 as a Corrections Officer before moving to Road Patrol Deputy in 2003. That’s over twenty years of experience within Tuscola County Sheriff’s Department, giving him deep institutional knowledge about how the department operates, what works, what doesn’t, and how to navigate organizational dynamics.
His promotion to Sergeant in 2016 marked his first step into formal leadership, followed by selection as a Detective in 2022 where he presumably investigated major crimes requiring analytical skills, attention to detail, and ability to build prosecutable cases. Now as Lieutenant, he assumes senior leadership responsibility for Road Patrol operations—essentially managing the deputies who respond to 911 calls, conduct traffic enforcement, investigate crashes, and handle the endless variety of situations patrol officers encounter daily.
Herman’s specialized positions mirror Zube’s in some respects—he’s also a certified drone operator and accident reconstructionist, showing the department values these skills across divisions. As Field Training Supervisor, he’s overseen the entire training program for new officers, establishing standards and ensuring consistent quality in how the department prepares personnel for the challenges of law enforcement work.
These promotions reflect broader patterns in law enforcement career development and organizational management. Similar to how Huron County Commissioners balance personnel decisions with budget constraints, and how Michigan State Police leadership faces scrutiny about organizational culture and decision-making, the Tuscola County Sheriff’s Department demonstrates how agencies develop leaders from within, promoting officers who’ve proven themselves through years of service and increasing responsibility.
Sheriff Robinson emphasized that these changes recognize the experience and dedication of personnel while supporting organizational transitions. That’s sheriff-speak for “we’re promoting people who’ve earned it and who we trust to lead effectively during a period of change.” Leadership transitions create organizational vulnerability if not handled well—losing experienced leaders through retirement can disrupt operations, demoralize personnel, and create knowledge gaps. Promoting qualified internal candidates provides continuity while creating advancement opportunities that motivate ambitious officers.
The February 14th effective date gives these officers a few days to prepare for their new roles, tie up loose ends in current positions, and mentally transition to expanded responsibilities. Promotions aren’t just title changes—they fundamentally alter your daily work, your relationships with colleagues who might now be your subordinates, and the weight of decisions you’re making.
For the Tuscola County Sheriff’s Department broadly, these moves signal investment in developing leadership from within rather than bringing in outside hires for senior positions. Agencies that promote internally demonstrate faith in their personnel development programs and create career pathways that encourage talented officers to stay rather than seeking opportunities elsewhere. Departments that consistently hire leadership externally signal that internal advancement opportunities are limited, potentially leading to retention problems as ambitious officers leave for agencies offering better career prospects.
Organizations like the International Association of Chiefs of Police provide resources on law enforcement leadership development. The National Sheriffs’ Association offers training and support specifically for sheriff’s office operations and management.
For Tuscola County residents, these promotions matter because leadership quality directly affects law enforcement effectiveness. Good supervisors make better officers through training, mentoring, and holding personnel accountable. Good leaders make smarter tactical decisions during critical incidents. Good administrators create department cultures that emphasize professionalism, community service, and constitutional policing.
The congratulations from the Sheriff’s Office to Detective Sergeant Zube, Sergeant Coleman, and Lieutenant Herman represents public recognition of their achievements while setting expectations for their performance in expanded roles. Public announcements of promotions create accountability—these officers now carry titles and responsibilities that the community will judge them on as they lead their respective divisions.
The photograph showing all three promoted officers together symbolizes the collaborative leadership approach the department presumably values. Law enforcement isn’t individual heroics—it’s teams working together, supporting each other, and coordinating efforts to serve communities effectively. These three officers will presumably work closely together despite being in different divisions, sharing resources, coordinating investigations, and ensuring smooth operations across the department.
Looking forward, these promotions create openings in positions these officers are vacating—maybe a detective position opens up with Zube’s transfer, or a K-9 handler position becomes available with Coleman’s promotion to Sergeant. Those opportunities allow other ambitious officers to advance, creating positive career development cycles where promotions create advancement opportunities cascading through the organization.
For the promoted officers themselves, February 14th represents career milestones worth celebrating while understanding that leadership brings new pressures and responsibilities. Being a good patrol officer or detective doesn’t automatically make someone a good supervisor—leadership requires different skills including personnel management, strategic thinking, political awareness, and ability to balance competing demands from subordinates, command staff, and the public.
Tuscola County Sheriff’s Department’s promotion announcements demonstrate how law enforcement agencies manage leadership transitions, recognize dedicated personnel, and develop the next generation of leaders who’ll shape department operations for years to come. Congratulations to Detective Sergeant Zube, Sergeant Coleman, and Lieutenant Herman on their well-earned advancements.
