Alexandria Bump

Alex is California North Bay born and raised. She attended Santa Rosa Junior College in the Architecture program. Her love of architecture and design stemmed from her great grandfather, grandfather, and father being carpenters. She loves environments that reflect nature and work with the environment instead of against it. Her hope for the future is that we can learn to embrace and incorporate nature into design on a daily basis, reinvent designs, and practices that are harmful to nature. Her goal when working on a project is to create a symbiotic relationship with clients, where communication and collaboration are key to creating an environment that is functional, beautiful, and unique to each client.  

Fun fact: In her free time she likes to be outside having fun, exploring somewhere, or just enjoying the tranquility of nature. She also loves to travel whenever possible. Being able to experience other people’s culture and history is truly a humbling experience, and an amazing blessing!
