Alarm Pros Plus provides peace of mind and asset protection for residences and small businesses.

After 20 years of working for the global company ADT Security Systems, Michael Petrillo of Arnold decided he wanted to “break away from corporate life and provide a more personal level of personal service to my own customers.”

Four years ago he opened Alarm Pros Plus by becoming a SafeStreetsUSA – ADT Authorized Dealer and began building his business by working from home.

As the business grew and he hired five local employees, Mike wanted a better location for running his busy dealership. So he became a Member at Corridor 55, the City of Arnold’s innovative coworking space for small entrepreneurial firms.

“I needed a place where I could handle administrative tasks with the type of professional conveniences to help better manage my business. Corridor 55 is very cost effective and convenient for entrepreneurs. Becoming a member was a no brainer,” says Mike.

“Our customers are people who may live alone, or they are elderly, or one spouse may travel often, leaving the other spouse alone or with children.

“They are worried about break-ins, property damage, and invasion of the premises or crime. They want protection. The same goes for small businesses that we serve.”

Empathetic Approach

“We take an empathetic approach to understanding and resolving our clients’ needs, and we provide world class products, services, and installation – not only in the Arnold and St. Louis areas, but in major cities across the United States.”

“Our alarm systems are the best made, with the best support. You won’t find them for sale in a big box store.”

As a Member at Corridor 55, Mike has 24/7 access to shared workspace, free use of secure internet wifi services, unlimited kitchenette privileges, printing, mail services, and discounted access to the modern conference room and classroom, plus free parking.

He is currently on a waiting list for a Corridor 55 dedicated office, which will increase the business amenities he can use there.

Alarm Pros Plus offers more than a dozen different products, services, and systems for residences that support:

  • Remote arm/disarm
  • Loud, high-pitched sirens
  • 24/7 burglary monitoring
  • Custom alerts
  • Custom notifications
  • Remote video security
  • Live video feed
  • See kids get home safe
  • Remote home control and automation
  • Lock and unlock doors
  • Adjust thermostat and control lights
  • Motion detectors that are immune to pet movements
  • And more

“Many of our customers are people involved in the moving process and want the home or office they will occupy to be alarm system protected starting the minute they move in,” Mike says.

“Our business has grown since we moved into Corridor 55, and we expect continued good growth now that we are establishing an affiliate program with real estate agents.

“Yes, our business is alarming – and we like it that way,” Mike says with a smile.
