Dr. House's veterinary career began in 2014 when she worked as kennel staff at her local veterinary hospital. After shadowing a veterinarian family friend, she immediately knew veterinary medicine was her calling. Even through her years of veterinary school, Dr. House remained a technician’s assistant with any off time she had. According to Dr. House, the veterinary profession is the perfect combination of all her interests in one place: teaching; science; problem-solving; giving back to the community; the necessity for continual learning, growth, and medical discovery; and the most adorable patients.
Dr. House grew up in Clinton, New Jersey, and recently relocated to Tranquility with her 13-year-old chihuahua named Sigmund by her side. Outside of using her science-driven mind at work, Dr. House has quite an artistic side! She enjoys painting, attending live music, board games, reading, dance, Broadway, travel and much more.

She now has quite the combination of animals between her house and her parents including 6 dogs, 2 cats, a rabbit, chickens, goats, and miniature horses. Outside of the clinic Dr Dena can be found hiking with her 3 dogs (Angel, Stevie Wonder, and Indiana Bones), camping, kayaking, or riding horses.
