Avisto was formed with the acquisition of Dallas based Eddye Dreyer Financial Services and subsequently with the purchase of Tulsa based The Resource Group. For almost 30 years, these entities: provided professional back office outsourcing to oil and gas entities and individuals; earned excellent reputations in the marketplace for employing talent individual capable of providing a broad suite of services; and were committed to creating value for clients by efficiently processing data at a lower cost than a full-time in-house alternative.
