Mahesh initially learnt from senior vidwan Sri G. Balasubramaniam at Chembur, Mumbai, who is a student of the well-known vidwan Tiruchi Swaminatha Iyer. Sri G. Balasubramaniam is also an adept at Thiruppugazh, and Mahesh was fortunate to learn many Thiruppugazh songs from him. Since 2007, Mahesh has been under the expert guidance of vidwan Sri G. Ravikiran, who is a senior student of vidwan Sri TM Krishna. Mahesh continues to learn from him at present. He is also associated with Guruguhaamrta, a trust founded by Sri G. Ravikiran to increase awareness about Muddusvami Dikshitar's brilliant compositions. Mahesh has performed at all leading sabhas in Bengaluru and Mumbai, and has been actively performing online for several sabhas this year.
