Lockhart Training in Carlsbad provides CPR, AED, First Aid, Pet First Aid, and Child and Babysitting Safety certification from its Glasgow Drive base in the 92010 zip code near Poinsettia Park. The company holds authorized Training Center status with the American Safety & Health Institute, the Emergency Care & Safety Institute, American Trauma Event Management, and the American Heart Association—credentials that support the same public-education mission as the Library Learning Center on Dove Lane. Mobile instruction brings group classes directly to businesses, community recreation centers, and private residences across Carlsbad and North County. Monthly community classes rotate through local venues, and the babysitter-safety curriculum aligns with the emergency-preparedness standards maintained by youth-serving institutions like Army and Navy Academy on Carlsbad Boulevard. AED-certification modules include live defibrillator pad-placement drills on adult and pediatric manikins, two-rescuer CPR sequencing with bag-valve-mask ventilation, and simulated choking-response scenarios for infants through adults.
