They might already have it, but this (https://www.amazon.com/Whitecoat-Clipboard-Lilac-Nursing-Edition/dp/B00GWSODHA) clipboard is loved by most healthcare providers. It comes in different colors too.
Getting him an nice engraved stethoscope is in that price range as well. I specifically mention it being engraved, because it makes it personalized, but he also won't have to worry about it getting mixed up with his coworkers'.
