Sustainability Consulting

Explore And Score Your Environmental, Social, & Governance Performance

Simmitri collaborates with leaders in North California’s sustainability consulting space, having worked with a versatile range of brands to improve how they interact with their customers and our environment. After speaking with global supply chain leaders like Apple, Boeing, Accenture, JP Morgan Chase, Salesforce, Nissan, Sysco, Kimberly Clark and more in DEI (Diversity, Equity, & Inclusion) and sustainability, we know they deeply care, but don’t know how to get there quickly enough.

On average, 60% of a company’s carbon footprint originates in its supply chain of manufacturers and global providers. Most large business entities in both private and public sectors are missing incremental sustainability targets because they can’t Green their supply chain (or themselves) fast enough. As a long-standing roofing and solar energy provider, we’re paving the way. Dramatically transform your impact by accessing Simmitri’s community engagement programs!

 Trustindex verifies that the original source of the review is Google. Simmitri installed our Enphase solar panels and later our battery system. They did a terrific job.   Our system runs well after three years. They were good to work with. Their office helped us with the California document submission. We are pleased!

 Trustindex verifies that the original source of the review is Google. After interviewing 3 solar companies I selected Simmiti for my dolar installation. The planning and submissions to PGE and SCCounty Building were done in a timely manner. The installation crew was superb. The inspector was highly impressed with the installation. Ana, my PM, stayed on all parties to get the final steps of approvals. I highly recommend Simmitri for your solar project. 9/12/2025 I just recently added 6 panels to my system (added e-car) and Pamela at Simmitri handled my project. Communication throughout the project was excellent and the crew, once again were FANTASTIC! Simmitri is a pleasure to work with.

 Trustindex verifies that the original source of the review is Google. We can say that installing and working with Simmitri was a seamless experience. They did exactly as they say they would. The staff is amazing to work with, especially the Project Manager Pamela Rodriguez and the Sales Manager Lonnie Cory. The installation crew was fast, clean and friendly. All in all, a great experience working with them from the beginning... and continuing. We are so happy with our new system!

 Trustindex verifies that the original source of the review is Google. Our project began in 2020 with the construction of our new home. When we were ready for our Solar installation, Jonathan walked us through every step of the way. The installation crew were fast, competent, and thorough. We couldn't have asked for a better experience!!
