We consider the detectability of the gravitational wave (GW) signal from an orbiting stellar-mass black hole (BH) with a mass of order 40 $M_{\odot}$ around Sgr A* at the center of the Milky Way galaxy. We simulate the sinking BHs to the center through dynamical friction and GW emission. We predict that LISA will detect of order 10 BHs at any given time with a signal-to-noise ratio $S/N > 10$.
