4.9/5 Average Rating

"We shifted our entire pharmaceutical cold-chain operation to AAT Supply Chain Solutions eight months ago. Since then, we've had zero temperature excursions and our on-time delivery rate to our hospital network across Los Angeles County improved from 91% to 99.3%. They understand regulatory compliance at a level we hadn't seen from any other carrier."

Beatrees Weninger
Director of Logistics, Southern CA Pharmaceutical Distributor

"Our Inland Empire manufacturing plant runs on just-in-time parts delivery. AAT's intermodal coordination with Union Pacific has cut our carrying costs by 28% while keeping our assembly line running without a single stoppage."

Shravankumar Ableson
Supply Chain Manager, Auto Parts Manufacturer

"Black Friday used to terrify our logistics team. With AAT's on-demand surge capacity for last-mile e-commerce delivery across the LA metro, we handled a 340% volume spike without a single late delivery complaint. That's unheard of."

Tashawna Lopguty
VP Operations, E-Commerce Retailer, Los Angeles

"We needed a heavy haul partner for our solar farm build-out in San Bernardino County. AAT managed all the CA-permitted routes, delivered our panel arrays on schedule, and their safety record on our job sites was impeccable. We've already booked them for our next project."

Gudalupe Gotter
Project Director, Renewable Energy Contractor, Orange County

"Switching our chemical distribution to AAT's hazmat-certified fleet took a compliance burden off our plate we didn't realize we were carrying. Their documentation process is airtight and their dispatch team is responsive around the clock."

Iohn Angelo
Operations Manager, Chemical Distributor, Riverside

"AAT handles our food & beverage cold chain from our Fontana facility to grocery distribution centers across Southern California. FSMA compliance is built into their process, not bolted on. My auditors haven't flagged a single issue in two years."

Treen Fishers
Quality & Logistics Lead, Food Manufacturer, Fontana CA

"As a mid-sized commercial contractor in Orange County, finding a reliable hauler for heavy equipment used to mean weeks of vetting. AAT had our permit paperwork, driver credentials, and delivery timeline confirmed within 48 hours. It's the partner we didn't know we needed."
