Sandi Weber

Executive Assistant

Sandi joined our firm in February 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. If you call or come into our office, she is most likely the first person to greet you.

Sandi lives in Cave Creek with her husband, Todd, and their three rescue dogs Peanut, Fudge and Gumball. When they aren’t being kept busy and entertained by their fur-children, they are enjoying life as new empty nesters! They have two grown sons, who are adulting very well!  Tristan, who is 21, lives in Tempe, is going to college, while working in the restaurant industry, as well as training for his Black Belt in Brazilian Jiu-Jitsu. Their other son, Ashton, who is 19 and a Freshman at NAU in Flagstaff, is focusing on his first year away from home and his studies. He is involved in several clubs and is enjoying his new college social life and freedom. He finished his first semester with straight A’s!  Sandi stays busy sending plenty of care packages to both boys and the post office knows her by her first name now!

Sandi originally hails from Ohio and is still a loyal Cleveland Browns and Ohio State Buckeyes fan, despite living in Arizona for 19 years. Ironically, she married a Michigan fan, who’s also a football coach, 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, weightlifting, walking, reading personal development, and staying mentally and physically fit. When she’s not busy being a football wife attending every game, or building her online social media brand, she enjoys traveling, watching television, sporting events, shopping, dining out or just staying home with her family, her happy place.
