John McGuire is an American citizen, a TV personality who is best known for his appearance in the reality TV shows Big Brother. He was born in 1988 and in 2015; his current age is 27 years old. John was born in Scranton, Pennsylvania, United States of America and currently resides in Jefferson Township, Pennsylvania. He was brought up in extreme poverty and was raised as the eldest of three children to a librarian couple. As a child, he attended a local public school and unable to pay for his high school, his parents educated him on loan. A serious and talent student, he often would study under merit and upon graduating high school, went on to the University of Pennsylvania where he studied dental science and became a dentist. An American by nationality, he belongs to white ethnicity and is a Christian by religion.  

John is a tall man, not the tallest but still has a pretty good height. He measures about 189 cm tall that is around 6 feet and a couple of inches, which is a very good height. His last recorded body weight was around 84 kg, which makes him a slim and lanky fellow. He admits that he has never been to the gym but likes to jog every day and also practices yoga. A funny and intelligent person, he says he likes to judge people on the basis of their intelligence and spontaneous. Reading books and listening to music are on his top list for hobbies, and for a dentist he seems to be pretty loud and unusual. When asked about what his motto in life was, he said “No God or kings, only man. Yeah, I stole that one, but it's so true.” He doesn’t have any shirtless pictures on the media, and surely hasn’t got a tattoo on his body.

At the age of 27, John surely isn’t married nor is planning onto do it anytime soon. He hasn’t been divorced before, nor any ex-wife or children of any sort. He has been very open about his relationship status and said that he had once had a girlfriend, but that was in his college. After the breakup, he started working and since then haven’t had the time to find a girl for him. “Now that I am on TV, maybe my opportunities will grow. Maybe” he said in an interview after the Big Brother season. He says that he enjoys his time alone, playing video games, getting drunk at times and playing guitar. When asked about his type of girl, he said that he would judge them by starting to act completely annoying and geeky, so they wouldn’t end up dumping him and no hearts are broken. He is not sexually gay, although rumors have been going around about it because of his low dating life.

John has never appeared in any TV shows, and that Big Brother’s season 17 was his first experience on television. He has been a big fan of the show and has been following it from some time now, and appreciates Nicole and Derrick who were on the previous season. Not much is known about his life, as his biography isn’t available in any sites like neither Wiki nor any other. After being famous on TV, he has had a massive fan following on Twitter and Instagram, which according to him is a good thing. With not many facts disclosed about him, his net worth has also not been discussed on the media.
