rachel gelberg
CEO, CREATIVE DIRECTOR, BRAND STRATEGIST, FOUNDER
Rachel was born and raised in New Jersey just outside of NYC. Recalling her experience as a scared 14 year old scrolling through Psychology Today seeking a practitioner, Rachel has vivid memories of feeling lost and overwhelmed. She remembers how hard it was to choose the person with whom she’d share her most vulnerable relationship with, basing her decision on what felt like an ocean of headshots and bios. Branding, and its visceral ability to connect practitioners with resonant clients, felt like the missing piece of the puzzle.
Years later, Rachel founded coBranding in 2019 with a decade of combined experience in design, branding, education, and corporate management. She combined her versatile skill set and passion for helping facilitate meaningful connections to develop a holistic approach to branding and design crafted to empower mental health practitioners.
Since then, she’s worked with nearly 200 brands, helping each one reach those who need them the most. She's excited to continue on with her mission to help practitioners help people through creativity, connection, and kindness.

Outside of coBranding, you can probably find Rachel spending time with family and friends, cooking eggplant parm while singing in the kitchen, playing instruments, or playing Mario Kart with her husband, Rob.
