How can I say "Not only he doesn't" with "pas seulement"?

Question

• Tony n’est pas seulement un excellent professeur, c’est aussi un scientifique de grand talent.

When I see the "pas seulement ~~~ aussi", it is almost always about the affirmative statement: "Tony is A, and B". But how can I turn this phrase into a negative statement, such as,

• Tony not only doesn't like playing with children in his neibourhood, but he also doesn't take a good care of his own children as well.

I can't imagine using "pas seulement pas" for "not only not".

Answer 1

You can turn it that way:

Non seulement Tony n'aime pas jouer avec les enfants de son quartier, mais il ne s'occupe pas bien de ses propres enfants non plus.

Answer 2

I rather would suggest :

Non seulement Tony n'aime pas jouer avec les enfants du voisinage, mais il ne prend pas non plus soin de ses enfants.

Answer 3

I will go with:

Non seulement il n'aime pas..., mais il ne prend pas non plus soin de....

Answer 4

I agree with the "non seulement" suggested by several answers.

However, note that "Tony n'est pas seulement" is already negative ("ne [...] pas"). It's literally "is not only"
