Take It From Our Happy Clients

Bill Fasoli

Director, ServiceNow, CISA/CISSP

Like his father before him, James is committed to learning proper waste disposal methods and following them to a tee. He has a passion for keeping our environment safe, and it shows through his dedication and commitment to his clients. I can’t recommend Mayfield environmental engineering highly enough.

Joanna Calderon

Realtor/Prop Manager, Huntington Beach

We do multifamily real estate and property management in Huntington Park and hired Mayfield Environmental because of ongoing homeless encampments, trespassing, and Hazmat they kept bringing that was quite the headache. We will be using them for environmental site assessments on our next acquisitions. Highly recommended.

Christopher Stahl

Longshoreman/Operator, Port of Long Beach

We had Mayfield Environmental Engineering do an evaluation before installing generators at our terminal in the Port of Long Beach. Because of all the industry that occurs here, we had to make sure the project was DTSC compliant. Their engineer did a great job! I would strongly recommend this company.
