Operations Management


Practice Owner

Petri enjoys being the boss and runs a tight ship. He always makes sure that his minions are in line and ready to give him lots of treats. If he isn’t willingly given treats, he has no issue with stealing what he needs. Petri has a total of six extra toes and is proud to be a fancy polydactyl cat.



Legolas is Petri’s right-hand man and does not mind reprimanding any employees that they deem to be out of line. He agrees with Petri’s philosophy on theft of food, and he is always hungry. Legolas only has three legs, so he and Petri balance each other out well.
