Seeking Voice Instructor (White Plains)

Singer Songwriter, guitarist looking for lessons to improve my control of lower and upper registers as well as general endurance as my voice often loses power after a few songs.
Natural register is somewhere between a low tenor and baritone and has jazz/blues/soul undertones but listen to most kinds of music with alot of vintage Bonus if you can travel to me (White Plains), and also if you can help with original song doctoring Thank you!
