Rooted in Monrovia
We know Monrovia block by block
Monrovia sits in the San Gabriel Valley foothills, with the 210 Freeway cutting across town and Route 66 running through as Huntington Drive and Foothill Boulevard. Our officers work it daily, from the Old Town shops along Myrtle Avenue to the Trader Joe's and Parasoft offices in the business corridor and the light-industrial rows near the 210. As a security company in Monrovia, we time each route to the real risks at that address, so a downtown retail pad gets nothing like the plan we run for a warehouse loading dock.

Local Coverage
Monrovia Landmarks & Districts We Patrol Around
Familiar local knowledge is what separates a Los Angeles County security company from a national one. Our supervisors and patrol officers know these locations by name.
Trader Joe's Corporate Headquarters
The national specialty grocery chain Trader Joe's runs its corporate headquarters from South Shamrock Avenue in Monrovia's business corridor south of downtown. Our officers provide lot coverage and gate checks around the campus so staff and vehicles stay accounted for after hours.
Parasoft Corporation Headquarters
Parasoft, an automated software-testing company founded in 1987, keeps its global headquarters on Huntington Drive in downtown Monrovia. We run overnight checks on the building entrances and parking levels so the offices stay secure when the corridor empties out.
Old Town Monrovia (Myrtle Avenue Historic District)
Old Town Monrovia is the roughly ten-block historic commercial core along Myrtle Avenue, lined with shops and restaurants and home to a weekly Friday-night street fair. Our foot patrols work the storefronts and side streets there, with added crowd-control presence for the Friday market.
Monrovia Station (Metro A Line)
Monrovia Station is an at-grade Metro A Line light-rail stop that opened in 2016 and anchors the Station Square district on the south side of the city. We patrol the platform approaches and the surrounding transit-oriented parking so riders and tenants have a steady presence day and night.
Aztec Hotel
The Aztec Hotel is a 1925 Mayan Revival landmark on Foothill Boulevard, listed on the National Register of Historic Places and closed since 2012. We keep a posted officer and run perimeter rounds on vacant landmark properties like this to deter trespassing and vandalism.
Monrovia City Hall
Monrovia City Hall houses the municipal government offices and council chambers a block east of Myrtle Avenue in the downtown civic area. We handle after-hours rounds and access control at civic buildings, covering entrances and lots once the offices close for the day.
Common Questions
Frequently Asked Questions
Quick answers to the questions Monrovia property owners ask us most.
How much does a security guard cost in Monrovia?
The cost depends on the type of service, how many coverage hours you need, and the size of the property. Armed and unarmed guards, mobile patrol, and standing posts each price differently, and there are no setup fees to get started. Call us at (805) 515-3834 for a free consultation and a custom quote built around your Monrovia site.
Do you patrol HOA and residential streets in Monrovia?
Yes. We run marked-vehicle patrols and foot checks through Monrovia's foothill neighborhoods, from Gold Hills and Mountain View to the streets above Old Town. Officers vary their timing on each pass, log gate and common-area checks, and document anything unusual so your HOA board has a clear record. We can set nightly rounds or a fixed posted officer, depending on what your community needs.
Can you cover the Technology Corridor and light-industrial sites along Huntington Drive?
Yes. The business and light-industrial corridor near the 210 and Huntington Drive, including corporate campuses like Trader Joe's and Parasoft, is a core part of our Monrovia coverage. We provide warehouse and commercial security, gate and access control, overnight lot checks, and alarm response, and we tailor each patrol route to the loading docks, yards, and entrances at your specific property.
Do you offer both armed and unarmed guards in Monrovia?
Yes. Americal Patrol is a licensed California security company, PPO-9557, providing both armed and unarmed uniformed officers across Monrovia and the wider San Gabriel Valley. Unarmed guards fit most retail, residential, and office settings, while armed officers suit higher-risk sites or after-hours industrial coverage. We will walk your property and recommend the right mix, then staff it with officers trained for that assignment.
