  We study the X-ray spectra of a sample of 19 obscured, optically-selected
Seyfert galaxies (Sy 1.8, 1.9 and 2) in the local universe ($d \leq 175$~Mpc),
drawn from the CfA Seyfert sample. Our analysis is driven by the high
sensitivity of NuSTAR in the hard X-rays, coupled with soft X-ray spectra using
XMM-Newton, Chandra, Suzaku, and Swift/XRT. We also analyze the optical spectra
of these sources in order to obtain accurate mass estimates and Eddington
fractions. We employ four different models to analyze the X-ray spectra of
these sources, which all result in consistent results. We find that 79-90 % of
the sources are heavily obscured with line-of-sight column density $N_{\rm H} >
10^{23}~\rm cm^{-2}$. We also find a Compton-thick ($N_{\rm H} > 10^{24}~\rm
cm^{-2}$) fraction of $37-53$ %. These results are consistent with previous
estimates based on multi-wavelength analyses. We find that the fraction of
reprocessed to intrinsic emission is positively correlated with $N_{\rm H}$ and
negatively correlated with the intrinsic, unabsorbed, X-ray luminosity (in
agreement with the Iwasawa-Taniguchi effect). Our results support the
hypothesis that radiation pressure regulates the distribution of the
circumnuclear material.
