-CEO
FOWLER OIL & GAS
“Remora Management is a relatively small oil and gas operator, and after doubling our asset size through an acquisition, our single accountant was quickly overwhelmed. Thankfully, a referral led us to Upstream, and they’ve been an absolute game-changer. Austin and Sheena stepped in and immediately got us caught up on everything from acquisition accounting to bank financial reporting, tax preparation, and lease operating statements. They were ready and willing to take on as much of the accounting load as we needed. Upstream has consistently been quick to say “yes” and fair in their billing. Now that things have settled down, they continue to provide reliable ongoing support—and we’re very glad to have them in our corner, especially if we double in size again.”
