Kattar was born to his beloved parents, Jamie Kattar and Sandra Kattar, in Methuen, Massachusetts, USA.
Elder Kattar leads a irrigation company; the fighter followed in his father’s footsteps, bought Combat Zone MMA and focused on promotion. Likewise, Jamie’s brother Kevin owns the Merrimack Golf Club.
His parents always supported him and never let his dream die, even though his father was unsure of his decision at first. So, he asked the fighter to take it off, and only then could he compete professionally.
They scraped into their front yard, and when the owner arrived after a few minutes, Calvin already had his father in a choke hole; since then he has won most of his fights in the ring and lost very few.
Calvin Kattar shares a strong bond with his siblings
Calvin isn’t the only child born to Jamie and Sandra; he has three brothers and one sister, namely Kylee Reynolds, Jamison Kattar, Keegan Kattar and Tanner Kattar.
Keegan is a professional horticulturist on a cannabis farm, according to his Instagram bio, @keegankatar. Likewise, Jamison is a firefighter and MMA promoter; he works with the fighter as his right hand and serves as Administrator of Combat Zone MMA.
Additionally, Tanner is the youngest and he has maintained a private social media account under @tanner_katar. Additionally, Kylee is a baby mama; she gave birth to son Reynolds in May 2022.
The siblings are very close and share an unbreakable bond; they always encourage each other to grow for the better and help each other become better people. The Kattar clan shared many memories on their social media sites, @calvinkattar, @kyleejean29and @jmsngeorge.
