Starting in 2023, Marcus began Letters from the Edge, a podcast dedicated to openly discussing and demystifying bipolar disorder, using his own experience with the illness, to make it better understood and have those living with it feel heard and appreciated. Episodes explore the ups and downs of bipolar while navigating fatherhood, relationships, career and everything in between.

Although its first season run was very short, Marcus plans to continue to podcast and return with an exciting second season sometime in 2025.
