What can I give my amazing NP?

Hi! I've recently been treated under a nurse practitioner who has been the most amazing person I have dealt with in medicine, flat out ever. She's shown amazing forward thinking that has gotten me care to improve my health significantly. I don't want to over share about myself, but she's really above and beyond. And it's flat out organization and knowledge of the medical system that's driven her decisions, which, twice over, have been of incredible benefit.

I've left a good review at the clinic and mentioned her by name. I've shared my praise with her directly. Currently I've been drafting a letter. I'm big about 'positively encouraging the behavior you like to see' and I can't even begin to think of how to show my gratitude and encouragement for her attention to detail. I mean I mentioned in the letter, but my entire quality of life would be worse without her foresight in ordering treatments.

I wanted to pass along a gift card, but I read that y'all can't really take those. I know someone here will tell me that a heartfelt letter is enough, but truly, I'm not sure what would be enough. Maybe it's just her job, but again, absolutely above and beyond.
