Trusted for 25 Years
Love’s has worked with The Phoenix Group for more than 25 years, and for good reason. As Environmental Manager, I measure partners by how easy they make my job. With Phoenix, I hand them a problem, check in periodically, and it’s handled—every time. They’ve taken on projects no one else wanted, solved issues others said weren’t possible, and consistently delivered on time, on budget, and without complications. They’ve saved the day on more jobs than I can count and made me look good in the process. When a confirmed release letter shows up, there’s no question who I call. For Oklahoma work, they’re the go-to team.

Nearly 30 Years of Trust
Love’s has worked with The Phoenix Group for close to 30 years, and the relationship has always been straightforward. When an issue comes up, I can call Phoenix, put them on it, and trust that it’s handled from that point forward. They’ve supported us through full tank replacements and have managed the entire process—from the field work to completing all paperwork with the city or state. Their approach is simple, efficient, and reliable. I don’t have to chase updates or worry about loose ends. They take it from start to finish and get it done.
