She headed to Paris on Monday with quite an entourage for a 15-year-old: her mother, Olga; her fitness trainer, Andy Hanley; her new coach, Henner Nehles; a hitting partner, Maxsim Fomine; and her agent, Gary Swain, the IMG veteran who has long worked with John McEnroe.

“The good thing about it is she really earned the wild card, and it wasn’t a gift,” said Nick Saviano, the veteran American coach who has been Anisimova’s main tennis mentor outside her family. “I’m excited for her, excited for her mom and dad, who have sacrificed a lot.”

Konstantin Anisimov, a burly, dark-haired, ebullient man, is Anisimova’s primary coach. He said he and Olga, who are from Moscow, moved to the United States in 1998 hoping to provide more opportunities for their first child, Maria, who was 10 at the time.

“My wife had relatives who had lived a long time in the United States,” he said. “They sent us an invitation to come visit this country. We visited it, and we liked it more and more, and we start thinking and taking it seriously.”

He said they also considered moving to Spain.

“We really like Spain, but then we recognized when we visited America that everybody who comes here is going to feel like home,” he said. “In Europe, you always feel like a foreigner because it’s a completely different culture. America is a united country where people come from all over the world, and after a couple of years, they feel this is home, you know?”

In Moscow, Konstantin said, Olga was an “accountant in the banking system” and that he was involved in “finance and banking.” Maria inherited some of her parents’ aptitudes. She graduated from the undergraduate business program at the Wharton School at the University of Pennsylvania, where she excelled on the tennis team. She is currently a director at Bank of America Merrill Lynch.

Maria, who was Amanda’s initial tennis inspiration, started playing at age 10 in Moscow and eventually set her sights on college tennis after the family moved to Florida to help her train. Amanda started playing at age 2 with her mother.
