Music Producer, Owner of Vault Recording Studio

Bob recorded, mixed and mastered all of the tracks on Katie’s first EP. In 1988, Bob started his first recording studio, “Alternative Studios” in his mother’s garage. He worked his way through college engineering and producing local Pittsburgh bands. After graduating from Robert Morris University with a business degree, he pursued a 28 year career with PricewaterhouseCoopers LLP, ultimately retiring as Managing Partner – but always followed his passion and continued to play, write and record music.

Inspired by their love of music, Bob, his wife Dana and their two sons Ryan and Brett embarked on a journey to create something more than just a recording studio. They envisioned a new and vibrant space were musicians of all kinds could connect, co-create, record and promote their music.

They purchased the old bank building on Neville Island and hired Los Angeles based Yanchar Design and Consulting Group, a premier design firm specializing in the design of high-end recording and post-production facilities.

In 2016 construction was complete and The Vault was born. With the addition of Jimmy Hoyson, the acquisition of the Neve 8058 and Bob’s retirement from PricewaterhouseCoopers, the Vault began operating commercially in 2018.  In addition to running the studio and related record label, Bob still actively produces and records projects for clients across all genre.

Bass Vocalist

Ryan Saeler sings the bass part on “Our Blessed Redeemer” in Katie’s first EP. Ryan’s enjoyment of and appreciation for music began at a young age in Butler, PA through singing in church as well as various school choirs. Things got deeply serious in the summer between 7th and 8th grades when his voice shifted into a register that would have him reading bass clef from then on. Ryan continued singing through high school including in various musical theater shows such as Joseph and the Amazing Technicolor Dreamcoat where he was nearly arrested for stealing the show as Pharaoh. Ryan traveled to New Wilmington, PA to continue his musical journey in Amish country at Westminster College where he minored in music while singing in choirs and vocal ensembles as well as causing a mass swooning event while reprising his role as Pharaoh. As Ryan continued to fall in love with singing at Westminster, he also fell in love while singing with his future wife Nora. Upon graduation, the pair moved to Austin, Texas for a couple of years while Nora continued her education at UT and Ryan continued singing at a church in the area. Ryan returned to Pittsburgh with his wife in 2004 where they began singing regularly at Third Presbyterian Church and still do to this day.
