THE ANATOMY OF THE COOL NERD

For people with a differential and a sense of humor.

The kind who appreciates clever over loud. Who notices the little details. Who still finds medicine fascinating. And somehow makes everyone else smile along the way.

HUMAN ILLUSTRATED BY A PHYSICIAN

No Corporate Clichés. Just Evidence-Based Sarcasm.

I'm Dr. C., a practicing pediatrician, and I started Good Prognosis because I couldn't find a medical shirt that felt like it came from inside healthcare instead of a hospital marketing committee.

I've been doing digital illustration for over 20 years so every design starts on my iPad, usually a phrase or a moment from an actual shift, sketched, redrawn, and picked apart until it's right. Then it gets printed on cotton good enough that you'd wear it even if nobody clocked the reference.

No healthcare-hero slogans. No recycled EKG-and-coffee graphics. Just clinically fluent designs, for the cool kind of nerdy.

I love the phrase on this T‑shirt, it really represents us as doctors. I love how nice it looks, it has a pleasant smell, and the size fits me perfectly.

Customer video review of It Sure Is Quiet Around Here Frog T-shirt

Love the color, feel, and quality of the shirt! It's a cute graphic too. I'm hoping it doesn't shrink in the wash. I'm wondering if I should have ordered one size up since it's unisex, instead of men's.

Customer video review of It Sure Is Quiet Around Here Frog T-shirt

Fun shirt to wear to work! My co workers loved it and I got asked so many questions on where I got it from. Love the cute pink color and quality. Fits perfectly without being tight or making me sweaty at work.

Customer video review of It Sure Is Quiet Around Here Frog T-shirt

This is such a cute T-shirt. I love the yellow color and T-shirt is very soft. The frog is very cute and helps to lighten the mood at work with friendly humor. I have received several comments on the shirt so far and will continue wearing it to spread smiles. The shirt runs small so size up if you want an oversized look.

Customer video review of It Sure Is Quiet Around Here Frog T-shirt

Overall, this is a great t-shirt. It fits well, it has great medical humor, and the frog in the scrubs is chef's kiss adorable. I love the fact that it has the worst phrase you can say in a hospital, which is "it's quiet around here." Overall, the collar is really comfortable even though it's high, and as a small, I can wear it as a big-chested woman and still have plenty of room. Overall, I love this shirt and I'm going to continue wearing it.

Customer video review of It Sure Is Quiet Around Here Frog T-shirt

I love the fit and the feel of the shirt. The decal seems very well printed and no lifting of missed stitches anywhere on the shirt. It's lightweight but still durable and not see through. 100% cotton so this is one of my favorites! Breathable so you won't overheat on the super busy days.

Great fitting shirt, warm and nice texture. Fits the body and great design as well. The material feels durable and comfortable yet light. Get yourself one

It Sure Is Quiet Around Here Frog T-shirt

I am loving my new shirt from a Good Prognosis. The fit is fantastic and yhe printing quality on the cat is really impressive with no flaws. Made from 100% cotton this is the kind of shirt I can wear every day. I laugh every time I see my reflection. I just love the cats expression and I know it mirrors my own when I can’t stop my face from reacting to other peoples comments.

Customer video review of Fever is Not Antibiotic Deficiency T-shirt

Very comfortable 100% cotton T-shirt. Straight out of the package it did have an odd smell. After washing the T-shirt it was gone. True to size.

Fever is Not Antibiotic Deficiency T-shirt

The graphic has a thick “painted on” texture which can be uncomfortable and does not breathe easily. If this could be fixed, it would be wonderful

Customer video review of That Wasn't Very Evidence Based of You T-shirt

Very comfortable t shirt! Great for work, running errands, or lounging around the house. I get compliments or questions about where I get these tshirts and it's a great way to meet new people. They make a great gift for healthcare workers and it's true to size as well!

Customer video review of That Wasn't Very Evidence Based of You T-shirt

I really like the color of the shirt. The print is cute too. The material and the fabric is super comfortable. I just dont like that the shirt had kind of a funny smell and i had to wash it before wearing it

This is such a cute shirt, the idea behind it is awesome and it’s so comfortable to wear, and doesn’t look or feel cheaply made!

Customer video review of Fever is Not Antibiotic Deficiency T-shirt

Wonderful shirt! I agree with the statement, it’s soft, and fits just right! It’s also a good shirt just to wear out and about. I love Comfort colors for graphic Tahoe’s because that are soft and wash very well.

I really love the shirt!! It is made with excellent quality and feels great. The fit is perfect and to have a company personally reach out about the product and the history behind it is top tier!!

Customer video review of That Wasn't Very Evidence Based of You T-shirt

This t-shirt is comfortable and roomy. The cats face says what most people think when they hear things like “I have healing rocks that have cured me.” Science has proven that healing rocks do not cure anything. It’s a fun and playful shirt that gets people talking. I’ve heard some wild stories about what has healed people so this shirt is perfect for me.

Customer video review of Fever is Not Antibiotic Deficiency T-shirt

This tee hits the mark on both humor and quality, the "Fever is Not Antibiotic Deficiency" message is an instant inside joke for anyone in primary care or pediatrics. The shirt itself feels substantial and well-made thanks to the heavyweight, 100% ring-spun cotton and garment-dyed wash, giving it a soft, pre-broken-in feel right out of the package. It holds its structured fit well through washes without the neck or seams stretching out.
