We present here the results of the analysis of the $\gamma$-ray blazar, 1ES1215+303, over a 10-year period, from 2008 to 2017, measured at high energies(HE; 200 MeV $< E <$ 100 GeV) by the Fermi Large Area Telescope (LAT) and atvery high energies (VHE; $E >$ 100 GeV) by Fermi-LAT and VERITAS. This is thelongest temporal study of this high-frequency-peaked BL Lac object (HBL) at$\gamma$-ray energies to date. The spectrum follows a log parabola over thistime period, and its HE and VHE spectra are well-connected. Its flux issufficiently strong at HE to allow us to bin the Fermi-LAT data in 3-dayintervals, enabling us to investigate the temporal evolution of the flux inunprecedented detail. Several flaring episodes were detected and evidence foran overall trend of increasing flux over the span of the 10 years was observed.These light curves, in addition to the spectra, are presented. This unique dataset will help us to advance our understanding of the underlying physicalprocesses in blazar jets.
