Sandi Weber

Executive Assistant

Sandi joined our firm in February of 2016 as our Executive Assistant. She has an Associate Degree in Business. She brings 30+ years of experience as an Administrative/Executive Assistant to our team. She is relocating to the East Coast to be in our satellite office there, but she will still be servicing your account with any administrative needs.

Sandi lives with her husband Todd, and their two rescue dogs, Fudge and Gumball. When they aren’t being kept busy with their fur-kids, they are enjoying life as empty nesters. They have two grown sons, who are adulting very well! Tristan, who is 23, lives in Tempe while attending ASU, as well as working, while also training for his Black Belt in Brazilian Jiu-Jitsu. Their other son, Ashton, soon to be 21, is going to be a Junior at NAU in Flagstaff this fall. He will be getting his first apartment off campus, working part-time, and enjoying his college life. Both boys are on the Dean’s List at their respective colleges. Sandi stays busy sending care packages to both frequently! 

Sandi originally hails from Ohio and is still a loyal Cleveland Browns and Ohio State Buckeyes fan. Ironically, she married a Michigan fan, so football season in their house is always interesting. Together, they have a passion for health and wellness, which includes a lifestyle of eating healthy, yoga, meditating, weigh-lifting, walking and reading personal development to stay mentally and physically fit. In her spare time, she enjoys shopping, traveling, entertaining, watching television/movies, dining out, live sporting events or just staying home with her family, her happy place.
