Core Values

Technical Integrity

We follow SEC and PRMS guidelines and stay current with industry best practices to achieve the most accurate projections (and classifications) of value possible. We will not book reserves we are not comfortable defending.


We support our conclusions with documentation and dialogue at every step.  We will not issue our final deliverable without your approval and confidence.


We will deliver a consistent product, crafted from repeatable workflows…on time, and on budget.
