Corey (Grant) Henderson – CEO & Owner of T.A.C.T. of Middle Tennessee

Corey (Grant) Henderson is the CEO and owner of T.A.C.T. of Middle Tennessee, a Nashville-based emergency biohazard remediation and decontamination company serving communities across Middle Tennessee. Henderson acquired ownership of the T.A.C.T. franchise in November 2023 after a career spanning military leadership, healthcare technology, medical-device sales, enterprise business development, and environmental services.

His transition from military service and corporate America into entrepreneurship reflects a leadership philosophy built around discipline, accountability, empathy, and what he describes as servant leadership. At T.A.C.T., those principles are particularly important because the company frequently enters customers' lives during some of their most difficult and traumatic circumstances.

T.A.C.T. of Middle Tennessee provides 24/7 emergency services covering biohazard remediation, crime-scene cleanup, suicide and unattended-death cleanup, blood and bodily-fluid cleanup, hoarding cleanup, mold remediation, odor removal, drug-lab cleanup, tear-gas remediation, crawl-space services, and other specialized environmental cleanup work.

Who Is Corey (Grant) Henderson?

Corey Henderson, who commonly goes by Grant Henderson, is a Nashville-area entrepreneur and business leader whose career combines military service, healthcare, technology, sales, and environmental services.

According to T.A.C.T.'s official biography, Henderson has called Middle Tennessee home for approximately two decades and is an alumnus of Middle Tennessee State University. Before entering entrepreneurship, he served as a commissioned officer in the Tennessee Army National Guard and completed a tour in Iraq. He subsequently assisted with the training of U.S. Army Reserve and National Guard units preparing for overseas deployments.

That military experience became an important foundation for his approach to leadership. Rather than viewing leadership purely through the lens of business growth, Henderson emphasizes responsibility toward employees, customers, partners, and communities.

Today, he applies that philosophy to T.A.C.T. of Middle Tennessee, where customers often require assistance after traumatic events, deaths, accidents, contamination, or serious property conditions.

Corey Henderson's Military Background

Henderson's professional journey began with military service.

Public professional information indicates that he served as an officer with the U.S. Army and Tennessee Army National Guard, holding leadership positions that included Officer Strength Manager, Convoy Platoon Leader/Executive Officer, Observer Controller/Trainer Team Leader, and Company Commander. His military career included service in Iraq and responsibility for training and leading personnel.

His experience in military organizations provided exposure to several capabilities that later became relevant to entrepreneurship:

• Leadership under pressure

• Operational planning

• Team management

• Accountability

• Training and development

• Risk management

• Mission-oriented decision-making

• Working within regulated environments

• Maintaining composure during difficult circumstances

These experiences are particularly relevant to the biohazard-remediation business, where customers can require immediate assistance and employees must follow established safety procedures while interacting with people experiencing highly stressful situations.

Henderson has described himself as a servant leader, a philosophy that has become part of how he positions T.A.C.T. in the Middle Tennessee market.

Education

Henderson attended Middle Tennessee State University, where his LinkedIn profile lists attendance from 2005 to 2007. He also attended Marion Military Institute, according to professional-profile information.

His background combines academic education with extensive practical leadership training obtained through military service and subsequent corporate positions.

He has also pursued specialized professional certifications related to environmental remediation, including:

• Certified Mold Assessor (CMA)

• Certified Mold Remediator (CMR)

• Lead-Safe Remodeler/Renovator

His LinkedIn profile indicates that the NORMI CMA and CMR certifications were issued in December 2024.

From Military Service to Corporate America

After leaving military service, Henderson moved into corporate America, building a career in healthcare, medical technology, and enterprise sales.

T.A.C.T.'s official biography says he worked in Cardiac Electrophysiology and Sleep Medicine, with professional responsibilities spanning Tennessee, the greater Southeast, and the Pacific Northwest.

His publicly available career history also includes positions with major healthcare and technology organizations.

He worked at Johnson & Johnson MedTech, including roles as a Clinical Account Specialist and Senior Territory Manager. Earlier, he worked as a Regional Sales Manager at ZOLL Itamar, a company focused on sleep-related medical technology. He later served as an Account Executive focused on large enterprise customers at Gartner.

This phase of his career gave Henderson experience in highly technical industries where relationship management, consultative selling, customer education, and business development are critical.

Rather than moving directly from the military into a small business, Henderson spent years developing commercial experience before eventually deciding to pursue entrepreneurship.

The Move Into Entrepreneurship

After years in corporate America, Henderson began looking for an entrepreneurial opportunity that aligned with his experience and personal values.

The decision ultimately led him to the biohazard remediation industry.

He became an owner of T.A.C.T. of Middle Tennessee in November 2023, establishing a local operation serving Nashville and surrounding Middle Tennessee communities.

T.A.C.T. of Middle Tennessee was established in 2023 and operates as a self-owned business. LinkedIn lists the company in the emergency and relief services sector, with headquarters in Nashville and a stated focus on emergency biohazard remediation, crime-scene cleaning, hoarding cleanup, odor removal, and mold remediation.

For Henderson, the business represented more than a conventional career change. It gave him an opportunity to combine operational discipline with a service-oriented mission.

What Is T.A.C.T. of Middle Tennessee?

T.A.C.T. of Middle Tennessee is part of the broader T.A.C.T. – The Last Responders network.

The company provides emergency biohazard remediation and decontamination services throughout Middle Tennessee and surrounding areas. Its service portfolio includes:

• Biohazard cleanup

• Blood and bodily-fluid remediation

• Crime-scene cleanup

• Suicide cleanup

• Unattended-death cleanup

• Homicide cleanup

• Mold remediation

• Hoarding cleanup

• Rodent-waste cleanup

• Odor removal

• Drug-lab cleanup

• Tear-gas remediation

• Crawl-space encapsulation

• Emergency vehicle decontamination

The company emphasizes 24/7 availability because many of the situations it responds to cannot wait for normal business hours.

T.A.C.T. also serves commercial customers and organizations including property managers, insurance providers, general contractors, medical institutions, correctional facilities, police departments, fire departments, and emergency medical organizations.

A Business Built Around "Tact"

The company's name is closely connected to Henderson's leadership philosophy.

T.A.C.T. explains its mission around the traditional meaning of tact: using skill and sensitivity when dealing with difficult situations.

The company states that its purpose is to help people during some of the most difficult situations of their lives so they can move forward.

This positioning differentiates T.A.C.T. from a conventional cleaning company.

Customers are not simply buying a cleaning service. They may be dealing with a death in the family, a traumatic incident, a serious contamination event, or an unsafe property condition. In these circumstances, communication, discretion, empathy, and professionalism can be as important as the technical remediation itself.

Henderson has explicitly connected this philosophy to his own leadership approach, saying that he wants T.A.C.T. of Middle Tennessee to operate through servant leadership, providing the appropriate level of service, compassion, and empathy for each situation.

Building Trust in a Sensitive Industry

One of Henderson's key challenges as an entrepreneur is building trust in an industry that customers may encounter only during emergencies.

T.A.C.T. positions itself around professional procedures, trained personnel, specialized equipment, and discreet emergency response. The company says it is certified, bonded, and insured and follows industry guidelines and recommendations.

The business has also developed relationships with property managers, home inspectors, pest-control companies, insurance stakeholders, and other professionals who can encounter situations requiring specialized remediation.

Recent company activity shows Henderson focusing on referral relationships throughout the Nashville and Middle Tennessee market. T.A.C.T. has emphasized partnerships where the referring business can maintain its primary customer relationship while T.A.C.T. handles specialized contamination or remediation work outside the partner's normal scope.

This approach allows the company to develop a network-driven growth model rather than relying exclusively on emergency consumer demand.

Expansion Into Environmental Services

Henderson's entrepreneurial activities have also expanded into the broader environmental-services market.

Professional information identifies him as President and CEO of Vanguard Environmental Services, where he has positioned the company around building science, environmental assessment, mold remediation, crawl-space services, testing, and education.

Vanguard's official website identifies Henderson as its Founder and Chief Executive Officer and describes his leadership as combining military service, healthcare, technology, environmental services, and business operations.

The expansion is strategically connected to his experience at T.A.C.T. Both businesses operate within the broader environmental-health and property-remediation ecosystem, although their positioning and service scopes differ.

Leadership Philosophy

Henderson's leadership philosophy can be summarized around four principles:

1. Servant Leadership

His military and professional experiences have shaped a leadership model centered on serving others.

At T.A.C.T., this means understanding that customers may be experiencing grief, fear, uncertainty, or embarrassment and responding appropriately.

2. Discipline

Military experience has given Henderson a strong emphasis on processes, preparation, accountability, and execution.

Those characteristics are particularly valuable in remediation work, where safety procedures and consistency matter.

3. Empathy

The nature of T.A.C.T.'s work requires employees to balance technical expertise with emotional intelligence.

Henderson's stated goal is to provide customers with the appropriate level of compassion and empathy for each situation rather than treating every job as a standardized transaction.

4. Professionalism

Henderson's corporate healthcare background also contributes to a strong emphasis on technical competence and customer communication.

The result is a leadership model that combines military discipline, corporate experience, and entrepreneurial flexibility.

T.A.C.T.'s Market Position

T.A.C.T. operates in a specialized market where speed, availability, technical competence, and trust are major competitive factors.

The company's Middle Tennessee operation serves Nashville and communities including Franklin, Brentwood, Murfreesboro, Smyrna, Mt. Juliet, and surrounding areas.

Its local presence is supported by a broader T.A.C.T. brand focused on emergency biohazard remediation.

For Henderson, the opportunity is to establish T.A.C.T. as a trusted regional provider while developing relationships with the professionals who regularly encounter situations requiring remediation.

That includes property managers, insurance companies, contractors, law-enforcement organizations, healthcare organizations, and other stakeholders.

Challenges Facing Henderson

Operating a biohazard-remediation business presents challenges that are very different from those faced by conventional service businesses.

The company must maintain technical and safety standards while responding quickly to emergencies. It also needs to recruit and train employees capable of dealing professionally with emotionally difficult situations.

Another challenge is educating the market.

Many people do not understand when specialized biohazard remediation is necessary or which responsibilities belong to restoration companies, property owners, insurers, pest-control companies, environmental professionals, or other specialists.

Henderson's emphasis on education and referral relationships is therefore an important part of his growth strategy.

The Future of T.A.C.T. of Middle Tennessee

Henderson's long-term opportunity is to continue building T.A.C.T. into a trusted regional emergency-remediation brand while expanding its professional referral ecosystem.

The company's recent activity suggests an emphasis on developing relationships with property managers, home inspectors, pest-control companies, and other complementary service providers across Middle Tennessee.

At the same time, Henderson's environmental-services activities create opportunities to build a broader portfolio around mold, indoor environmental conditions, remediation, moisture, and property-related environmental problems.

His combination of military leadership, healthcare experience, corporate sales, entrepreneurship, and environmental-services expertise gives him a distinctive background for building companies in this sector.

Why Corey Henderson Matters

Corey (Grant) Henderson represents a different kind of modern CEO story.

Rather than coming from a traditional technology startup or venture-backed company, his entrepreneurial journey began after years of military and corporate experience.

His transition into biohazard remediation is particularly notable because the business requires both technical execution and human sensitivity.

T.A.C.T. operates in circumstances where customers often need more than a contractor. They need someone who can arrive quickly, understand the situation, explain the process, and handle the work with professionalism and discretion.

Henderson's stated emphasis on servant leadership is therefore closely aligned with the fundamental requirements of his industry.

His story also illustrates how leadership skills developed in one sector—military operations, healthcare, enterprise sales, and regulated environments—can be transferred into entrepreneurship.
