"I am extremely excited to continue working with some of the most passionate, hard-working, and talented coaches and athletes on the East coast!"

Brandon is in his 2nd season of coaching with Metro. He is the head coach of the women's varsity volleyball team at Georgetown Day School, where the Mighty Grasshoppers won their first state championship in school history in 2022 after achieving a #1 state ranking, a #8 ranking in the Mid-Atlantic Region of the US by USA Today and the AVCA, and having reached the final four of the DC State Tournament in each year since 2016. Following the 2022 season, Brandon was selected as the 2022 Washington Post All-Met Coach of the Year and the 2022 DCSAA Coach of the Year, with the Post writing: "In six years as head coach, Wiest has taken the Grasshoppers from the lower division of the Independent School League to the ISL AA Final two years in a row. Wiest capped off this season by guiding Georgetown Day to its first DCSAA title, putting GDS (22-3) on the map as a volleyball powerhouse."

Following the 2021 season, Brandon was also named High School Coach of the Year for the Mid-Atlantic Region by the AVCA. Brandon has coached club volleyball in the CHRVA region for seven years, qualifying teams for USAV Nationals and sending former players to play at the Division I, II, and III level and with the USA Youth A1 National Training Team.

In August 2019, Brandon shadowed UNC head coach Joe Sagula and his staff as the Tar Heels kicked off their 2019 season, being fully immersed in the planning and execution of practices and film review sessions throughout the preseason. He was fortunate to repeat this experience with the University of Maryland coaching staff and team during their 2022 preseason. Brandon has coached for several years at the UNC Chapel Hill, University of Tennessee, and American University volleyball camps. He has annually attended Gold Medal Squared and Art of Coaching Volleyball clinics, as well as the AVCA Convention and NCAA Final Four every year since 2017.
