Transforming a Promotional Benefit into a Core Product Experience
The SimplePractice Calendar is used by therapists, clinicians, and wellness professionals to schedule, manage, and track client appointments, all in one place within their EHR platform, accessible on both web and mobile.
Originally, all events in the calendar appeared in a uniform grey color, regardless of type or purpose. While functional, this design made it hard for users to quickly distinguish between sessions, personal events, cancellations, or reminders, especially when managing packed schedules.

"I had the pleasure of working closely with Diya where she took full end-to-end ownership of a new billing solution. From the start, she showed a strong ability to navigate ambiguity, ask thoughtful questions, and quickly build a deep understanding of the problem space. She communicates her thinking clearly and takes initiative to collaborate with cross-functional teams, which made her a really effective partner. She’s also incredibly organized in her work, bringing structure and clarity to complex problems. Diya brings a contagious sense of positivity and curiosity that makes her an absolute joy to work with. I would highly recommend working with her. Any team would be lucky to have her."

Josh Waldman
Senior Product Designer (Insurance Team) @ SimplePractice
"Diya consistently goes above and beyond to communicate with stakeholders, quickly identifying gaps in understanding and pushing for design excellence through quick iteration and rapid feedback cycles while showing a high level of ownership and initiative. Insurance is a complex problem space, and Diya uses all of the tools at her disposal to learn about the space and push for common sense solutions. Diya’s willingness to experiment is great to watch, and I’ve been consistently impressed by the quality of her design work. Watching her growth has been great to watch; she’s a great thinker who would be a huge asset to any design team."
