Master of sports of international grade, in 1991—1997 Shishkin played for national teams of USSR, Former Soviet Republics and Russia.

[5][6] From 2002 Shishkin is an owner and CEO of holding company Tactics Group,[7] leading investment, redevelopment and construction business projects in Moscow.

[20][21] As Shishkin himself recalls, he dreamed of being a professional volleyball player since childhood: as early as at the seventh grade of school he bet with his classmates that once he would become a member of a national squad.

Him being significantly shorter than his peers threatened to ruin all the hopes for sports career, nevertheless Shishkin was determined to overcome this obstacle: he studied multiple medicine volumes and developed a personal ‘growth system’:[22] I tilted my bed at an angle of 45°....Tied the legs down and slept headfirst.

[40][52][6] In season 1999-2000 Shishkin transferred to Italy again,[53] this time joining Quattro Torri Ferrara,[54][55] that turned out to be the last club in his professional sports career.

[58][59] Still being a professional sportsman, Shishkin started his first business endeavour: a restaurant named ‘Shishka’ on Moscow's Petrovka Street, following with one more on the Dolgorukovskaya st.

In an interview for RBK Daily Shishkin recalls closing the restaurant's first thing upon receiving the MBA, because they needed significant investments with relatively low income.

[63][12] Over the subsequent decade the venture grew into a massive retail chain with own production and numerous points-of-sale in different regions within the state.

The first canteen of the future chain was opened in Tactics Group's Vivaldi Plaza,[57] soon followed by the second place in ‘Preo8’ business centre at the Preobrazhenskaya square.

[64][61][65] Even more ambitious project has lately been added to the Tactics Group portfolio: the Bolshevik's (a former confectionery in Moscow) redevelopment in partnership with O1 Properties, previously owned by Boris Mints.

[61] The partners planned to redevelop the site into a multifunctional complex with a modern arts museum, office and residential premises, a park, and public spaces.

[68] According to Shishkin, the key purpose of the project was, first of all, to open formerly closed area to all citizen, and secondly — to create an influential zone of attraction, a place of interest on the city's map.

[71][72][73][74][75][76] The Moscow Urban Forum held in 2017 honored the Bolshevik's redevelopment project with the special prize as the most successful case of renovation by means of private investors.

[82][8] In 2017 Pavel Shishkin was nominated for RBK premium ‘Investor of the Year’ as one of the entrepreneurs with the highest annual revenue growth.

“Detskiy dom” is focused upon long-term projects aiming to help in socialization, education and full-scale development of children,[86][87][88] employment assistance for the graduates.

[14] One of the foundation's key priorities is the development of small family-type groups for no more than ten children, where life and education processes are similar to regular families.

[98][99][100] The rules and criteria of the tournament are fully congruent to the international Olympics,[101] team and personal competitions are held in swimming, tennis, athletics, and more.

[103][104] Famous sportsmen, celebrities, singers and bands take part in the events, and the authentic Olympic Flame is used at the opening ceremony.

[110][43] Retiring from the professional sport, Shishkin immersed into studying the history of religion, started meditating, made multiple pilgrimages, met such orthodox religious leaders as hieromonk Makariy (Makienko) at Saint Panteleimon Monastery, hegumen Joseph (Krjukov) at Optina Monastery, Indian guru Sathya Sai Baba, Tibetan Buddhist leaders Chökyi Nyima Rinpoche and Trulshik Rinpoche.
