Professional Interests:

My favorite part of being a veterinarian is working closely with pet owners to create thoughtful, individualized care plans for their animals. I’m especially passionate about surgery, internal medicine, and emergency medicine. I’m committed to being a lifelong learner and love staying current as new research and clinical advances continue to shape the way we practice veterinary medicine.

Personal Interests:

I’m happiest outside, preferably moving. Running, hiking, skiing, and adventuring with my husband and our three dogs are what fill my cup. I love having something to train for—whether that’s a marathon in a new place or tackling the Power of 4 (summer or winter). When I’m not chasing a challenge, you’ll find me in the garden, happily getting my hands dirty and harvesting whatever I can grow. I’m always curious, always learning, and always up for the next adventure.

Personal Interests:

It is a great pleasure to be part of the Aspen Animal Hospital team. I am deeply grateful for the opportunity to dedicate my love to animals and practice my profession, and I hope to reciprocate the love I receive from our patients & clients.

Outside of work, I enjoy a variety of outdoor activities — from skiing and mountain hikes to picnics in the park with good friends, bread & cheese, and dogs running free. Charcoal barbecues and cooking Brazilian meals surrounded by good company also bring me a lot of joy. Anything I can do with my dogs makes me happy, and someday I hope to have a horse again to make it all perfect. On weekends, you will find me exploring the beautiful nature of Colorado with my dog, Adele Griffon.

My long-term goal is to study animal behavior and write a book from the back porch of my farm, watching the environment and the interactions between species. Thank you, Aspen, for welcoming me with open arms!
