Meet Our Officer Instructors

Learn to Drive from Police Officers

Our TopCops Classroom and Driving Instructors are from many different law enforcement agencies in the Boulder County and Denver metro areas. The diversity of backgrounds in our first responders make young drivers comfortable behind the wheel. We prepare students at a cognitive and emotional level to accept and understand the responsibility associated with driving by developing their SIPDE (Scan, Identify, Predict, Decide, Execute) skill set. This exceptional training can only be offered by trained and decorated police officers and first responders found exclusively at TopCops Driving School!
