Alexa & Katie is a Netflix sitcom about lifelong best friends who face a crisis that turns them into outsiders at the very moment high school is supposed to be about fitting in. Created by Heather Wordham, the series follows Alexa Mendoza, a high schooler living with cancer, and Katie Cooper, her best friend, as they navigate freshman year together.
The show premiered on March 23, 2018 and ran for four seasons across 39 episodes, concluding on June 13, 2020. It stars Paris Berelc as Alexa and Isabel May as Katie, with Tiffani-Amber Thiessen as Lori Mendoza, Emery Kelly as Lucas Mendoza, Finn Carr as Jack Cooper, Eddie Shin as Dave Mendoza, and Jolie Jenkins as Jennifer Cooper. Matthew Carlson served as showrunner.

The Core Pair
The heart of Alexa & Katie is its central friendship. Alexa and Katie are best friends who have always been there for each other. When Alexa’s cancer diagnosis forces them to feel like outsiders, Katie responds by making an important decision: she shaves her head with Alexa.
That act of solidarity is the show’s emotional anchor. It tells you everything you need to know about these two characters in one scene.
Comedy and Cancer
The series balances comedy with a serious subject. Alexa’s cancer diagnosis is not a punchline. It is the reason the girls feel like outsiders at a time when fitting in matters most. The show tries to find humor in the chaos of high school while holding onto the weight of its central conflict.
Supporting Players
The ensemble around Alexa and Katie includes:
- Emery Kelly as Lucas Mendoza
- Finn Carr as Jack Cooper
- Eddie Shin as Dave Mendoza
- Jolie Jenkins as Jennifer Cooper
These characters fill out the world of the show without overwhelming the core relationship between Alexa and Katie.
Why It Works
- The chemistry between Paris Berelc and Isabel May anchors every episode.
- The head-shaving scene lands because it comes from a genuine place.
- The show finds humor in the mundane details of high school life.
- The cancer storyline is handled with care rather than cheap drama.
What Holds It Back
The show is not perfect. Some episodes lean too heavily on broad jokes at the expense of emotional depth. The pacing can drag in middle episodes of longer seasons.
But the strengths outweigh the weaknesses. The show commits fully to its premise and follows through on the promise it makes in its first episode.
A Solid Premise
| Element | Strength |
|---|---|
| Central relationship | Strong chemistry, genuine stakes |
| Head-shaving scene | A defining moment that pays off |
| Humor | Balanced with real emotion |
| Ensemble | Supports the main pair without distracting |
Alexa & Katie is a sitcom that knows what it wants to be. It is a show about friendship, cancer, and the strange pressure of adolescence. The writing holds together, the actors deliver, and the premise pays off over its full run.
It is not a perfect series, but it is a solid one.
