Christina Haack, formerly Christina Hall, rose to fame on the series Flip or Flop alongside ex husband Tarek El Moussa. She loves to share moments from her life with fans and followers as she launches new brands, publishes books and buys and sells real estate.

Christina Hall Has One Sister

Christina’s sister, Carly Haack, is 10 years younger than the HGTV star. A native of Anaheim, California, Carly tends to keep to herself, unlike her big sister, who has 1.8 million followers on Instagram. Still, the world got to know a little bit about Carly after Christina shared a post in August 2023 wishing her “beautiful, fun and free-spirited sister” a happy 30th birthday on the platform.

Who Is Christina Hall’s Sister Carly Haack?

Carly is a research scuba diver and wetland ecologist. The former scuba instructor clearly loves all things outdoors, as in addition to being a professional diver, she’s an avid skier, sky-diver and hiker. 

Like her sister, she’s also a dog mom to a pup, Beau, that’s often featured in her socials wearing an adorable life preserver out on the water. Though, her own path in life couldn’t be further from the high-profile house-flipper’s television career.

What Does Carly Haack Do?

The UC Santa Barbara alum, who also holds a master’s in Marine Biology and Ecology from James Cook University, now works for UCSB as a boat safety officer, providing training and oversight for UC Santa Barbara’s boating and scientific scuba diving operation. She was previously a research associate at SONGS Mitigation Monitoring Program based in the university’s Marine Science Institute, handling dive sessions, artificial reef surveys, boat operation and environmental monitoring.

Over the course of the brainy boater’s education, she’s traveled far and wide on research expeditions, diving in Costa Rica and the Channel Islands.

Before beginning her adventurous scientific career, she also worked as a scuba diver for SeaWorld, responsible for maintaining the water quality in the park’s tanks and helping to train new employees.

She also produces and posts training videos on her YouTube channel that teach others proper boating and diving safety measures.

What Is Christina’s Relationship With Carly Like?

Christina and Carly seem to have a very close sisterly relationship, despite the 10-year gap between them.

In addition to Christina’s sweet birthday post, Carly apparently has a great relationship with her sister’s children.

Christian shares Taylor and Brayden, who were born in 2010 and 2015, respectively, with her first husband Tarek El Moussa, and Hudson, born in 2019, with second husband Ant Anstead.

In fact, Carly even published a book dedicated to her niece and nephews. The book, titled Search for the Magic Pearl, was written and illustrated by the outdoor enthusiast “with lots of love” and depicts Taylor, Bradyden and Hudson on an underwater quest to find a perfect Mother’s Day gift for sister Christina.
