Hobbies/Interests/Family: As a former gymnast, I love doing anything active including running, Peloton (@notjustken), OrangeTheory Fitness, waterskiing and downhill skiing. My husband is active-duty military, so we have lived in various places but are very excited to call San Diego home. Being new to the area, we enjoy exploring neighborhoods and trying new restaurants.
