"We moved our business from a smaller local firm to Matheson because we wanted greater confidence in our external counsel’s willingness and ability to keep the transaction on our desired timeline. Matheson consistently delivered on their promises thereby compelling other parties to stick to their agreed schedules. Matheson instilled confidence not just in our internal stakeholders but in all parties to the transaction that everything was being managed professionally and expediently."
