  • Mahi is a short-haired golden lab who has been the undisputed ‘employee of the month’ winner ever since the award was created! Admittedly, Mahi is not the most finance-savvy member of the team (new toys and/or opportunities to get head scratches distract him from long-term planning), but he brings great joy to the office and all of our clients who visit.

    In his spare time, Mahi enjoys napping, long walks with plenty of interesting scents, and trying out the best new treats the local market has to offer.

  • Mako is a black lab who has been a beloved member of the team since day one! He approaches each day with boundless enthusiasm, greeting every visitor like a long-lost friend and ensuring the office atmosphere stays upbeat. Spreadsheets and strategy meetings may not be his strong suit, but when it comes to boosting morale, Mako is unmatched.

    Outside of “work hours,” Mako loves going on walks, sniffing out every interesting scent, and playing fetch. He’s also a connoisseur of treats and has a remarkable ability to convince anyone that he deserves “just one more.”
