Some are not born as trend setters, they become trend setters.

We at The Gangwar ER-DR Institute believe in personifying this quote again and again by coming up with some or the other latest ways and techniques to make our students accelerate the pace of their preparation in their desired domain.

Being an educator for last twelve years, I comprehended a need for some novelty to be added time-to-time to meliorate the monotonous preparation pattern. Our venture of presenting Biology (Zoology and Botany) as one subject under one roof endorsed us as the early bird in Medical competitive domain. Our belligerent approach compelled us to muster our zeal to reinvigorate the old and tedious study patterns by introducing different avenues like different mobile applications and video lectures etc. to have our widespread reach to students across the country. Flair for writing allured me to experience, analyze and pen down for many prestigious publication houses which propelled me further to ripen in understanding the need of our students. This journey had not been remarkable, if I would not have got the inexhaustible support of my team. We are a team of highfliers and staunching faculty at The Gangwar ErDr Institute who have proven their mettle in their respective forte. Everyone from my team has been contributing to produce a large number of success stories by proving their expertise in their respective arena.

We are the gateway to your dreams. Join us to conquer the race.

Sincerely yours,
Dr. Hariom Gangwar
