Our mission is to ensure medical emergencies in Johnson County have the best possible outcome. We provide 9-1-1 response to over 535,000 citizens across 476 square miles with dual paramedic crews operating ambulances from 17 fixed ambulance stations and a single paramedic first response from two fixed stations.  Our values Excellence, Trustworthy, Humility, Integrity, Compassion, and Service guide us toward creating a continuum of out of hospital medical care, a prepared community and a community-wide feeling of safety and confidence.

Response to medical emergencies in Johnson County is a coordinated system consisting of response by Med-Act ambulances, often augmented by local fire department personnel.  Some of these firefighters are also paramedics.  All agencies operate under a common set of medical protocols that are approved by the EMS Committee of the Medical Society of Johnson and Wyandotte Counties.  Med-Act works closely with each agency to assure a smooth continuum of care for medical emergencies.

Special Operations

Tactical Medical Team (TMT)

Med-Act's Tactical Medical Team (TMT) provides immediate medical support for the law enforcement tactical teams of Johnson County, Kansas. These teams include those from the cities of Lenexa, Olathe, Overland Park, Prairie Village, Shawnee Police Departments, and the Johnson County Sheriff's Department. The TMT supports the Explosive Ordinance Disposal Teams of Overland Park Police and Olathe Fire Departments. The TMT also enjoys a close training relationship with the Kansas City Metro Tactical Officer's Association, by doing medical standbys during courses and providing instructors for the TEMS class and teaching Officer first aid.

Hazardous Material Medical Support Team (HMMST)

In 1993, Johnson County Med-Act created the Hazardous Materials Medical Support Team (HMMST) to respond to incidents involving chemicals that require specialized medical evaluation and support. The team consists of paramedics who have acquired training specifically to support fire department haz-mat response teams.  The HMMST members are specially trained to provide medical support for hazardous materials incidents, including providing effective medical care for contaminated patients.

Disaster Medical Support (DMS)

The Disaster Medical Support (DMS) is comprised of specially trained and equipped paramedics to provide medical support for technical rescue incidents such as building collapse.  Members of the DMS are able to work at any level within the Medical Branch as needed to support complex incidents.

Emergency Operations Team (EOT)

The Emergency Operations Team (EOT) coordinates the delivery of emergency medical services  under adverse operating conditions. Team members are familiar with the Johnson County County Emergency Operations Plan (CEOP) and its methods of activation, as well as the emergency operations with county, regional, state and national agencies.  During severe weather, mass casualty incidents, and/or special system needs, the EOT activates the department's operations center, known to the organization as the Emergency Medical Services Operations Center (EMSOC). The EMSOC provides a command and control center for all EMS activities and operations. Located at headquarters, EMSOC ensures system stability by adequately staffing of ambulance and rapid response units, strategically placing units, monitoring impending weather conditions and other system stressing causative factors, and facilitates additional resource requests.

Bicycle Medic Team (BMT)

Med-Act’s Bicycle Medic Team (BMT) began in the summer of 2003, and has proven to be an effective way to deliver care when reaching patients becomes difficult at planned events.  Every year there are several large events held in Johnson County where the team has proven very useful. These include the Johnson County Fair, Old Shawnee Days, and Old Settler’s Days.  

Each bicycle is set up to operate independently, although most often the BMT paramedics work in teams of two. In its panniers, each bike carries an AED, Oxygen and airway equipment, IV supplies, and medications to effectively provide initial treatment until a transporting ambulance arrives.

Standby Team

Large crowds at public events can present unique challenges in gaining quick access to those in need. Med-Act's Standby Team provides dedicated paramedics to select large scale public events, trained and equipped for rapid access and care. 


Station and Fleet Information

Med-Act units are located throughout Johnson County to provide advanced level emergency care with optimum response times.  While each EMS unit has a defined response district, the districts are only representative of what is generally the "first due" area for a given station while the system is at rest.  For each emergency call, the closest available response unit is determined by GPS location.

Ambulance Stations

Med-Act has seventeen ambulances that are strategically stationed around Johnson County.  Station locations are chosen after a response time analysis optimizes coverage based on historical patterns of emergency calls.  Med-Act has ambulances in fifteen local fire department stations, and two are housed and maintained in stand alone ambulance stations. Sixteen ambulances are staffed 24-hours a day, augmented by an additional ambulance that is staffed during weekdays, coinciding with peak demand times. Additional reserve ambulances are deployed around the county to help support maintenance and provide surge capacity for disasters.

Each station has heated garage space for response units. Office and living quarters are provided to support the twenty four shifts worked by paramedics.

Paramedic Advanced Response (PAR) Units

Med-Act also operates two PAR units consisting of a single paramedic with advanced life support capability, to provide additional quick response in the western and southern areas of Johnson County.  These are staffed 24 hours per day, and are housed with local fire departments.  Additional reserve PAR units are used to provide dedicated paramedic staffing for special events, such as Old Settler's Days or certain sporting events.  The department currently uses Ford Expeditions as the vehicle for PAR units.


Med-Act Headquarters is housed at 11811 South Sunset Dr., Suite 1100 in Olathe, Kansas at the Sunset Office Building. This location is in the center of Johnson County.  While most of the population currently resides to the north and east portions of the counties, the south and western portions of the county are seeing tremendous growth.  The current site of headquarters opened in April of 2006. Headquarters houses all administrative staff, with the exception of field supervisors. It is also the location of choice for team trainings, council and group meetings, some community education programs, and point of contact between the department and outside agencies.  The Emergency Operations Team operates their Emergency Medical Services Operations Center (EMSOC) activities out of this office during severe weather or emergency conditions.


Med-Act has two different types of ambulances.  Most are Type III ambulances, consisting of a modular patient care compartment mounted on a van chassis.  A few are Type I ambulances, consisting of a modular patient care compartment mounted on a truck chassis.  The patient care compartment is custom designed to allow for the paramedic to safely care for the patient being transported.  Five ambulances are operated jointly with the Overland Park Fire Department.  These have a significantly different external appearance than other Med-Act ambulances - they are red and carry both the Med-Act and OPFD logo.  Ambulances carry a wide variety of equipment: including radio and internet communications, diagnostic equipment, medical supplies. stretchers and other equipment to move patients.


Field Crews

Paramedics are on hand 24 hours a day, seven days a week, including holidays, to serve the public. Johnson County Med-Act paramedics work 24-hour shifts.  They may sleep during the shift, but must be able to quickly respond to the ambulance in the event of an emergency call. Crew members must be prepared to respond to a variety of things that can happen on an emergency incident. Some of the major challenges faced are mass casualty or multiple patient situations, dealing with life and death situations, risks from emergency driving and performing in inclement weather.

Paramedics work a modified Berkeley shift schedule of alternating days of 24 hours on-duty and 24 hours off-duty for a total of three shift days over a five day period.  The paramedics then enjoy four days off in a row to recharge, and recuperate for another rotation of shifts.

Crews are composed of two paramedics. Each two-person team is led by an officer, either a captain or lieutenant. The officer provides medical leadership and guidance for all personnel who are part of the on-scene EMS team. The team may confer with each other about decisions to be made, but the officer has the final accountability and bears primary responsibility for any actions taken by the EMS crew.


Med-Act Battalion Chiefs (BCs) assure the delivery of high quality emergency medical services and maintain a supportive, progressive, participative and quality oriented work environment. There are six Battalion Chiefs, with two assigned to each of the three shifts (A, B or C). Each shift is divided into the North Battalion (BC1103) or South Battalion (BC1105).  Battalion Chiefs are responsible for six to seven field crews. The Battalion Chief oversees the performance of Paramedics and is a critical component to the future development of leadership skills in each Officer and Paramedic. Battalion Chiefs are frequently dispatched to calls of serious clinical nature, multi-patient calls, unstable crime scenes, calls involving entrapment of patients, and to calls that have multiple agencies responding to the scene.

Battalion Chiefs report to a shift commander, who carries the rank of Division Chief.  The shift commander is responsible for coordinating effective EMS and overseeing needed operations.  The shift commander is available for response to particularly complex events when needed. 

Support Services

The Support Services Division for Johnson County Med-Act consists of four employees, led by the Division Chief for Support Services. It is a subdivision of Operations, and provides the vast majority of equipment and supplies necessary for Med-Act personnel to conduct EMS activities 24 hours a day, seven days a week.  This team is housed in a 5,500 square foot facility near the center of Johnson County.

This Division is responsible for vehicle maintenance and repair, restocking, retrieval of reusable equipment from hospitals and sterilization procedures.  The Support Services Division also handles bid specifications for emergency equipment and vehicles, retrofitting and installing emergency equipment in new vehicles.
