Our Story
From a Small Office in Charni Road to Mumbai's Most Trusted CA Firm
The story of Casela Advisors begins with a bold decision. Our founder, CA Nainit Digesh Savla, walked away from a senior position at a Big 4 firm — not because he had to, but because he believed there was a better way to serve clients.
"10 years ago, I quit a high-paying job at a Big 4 firm to start something. I didn't have a perfect plan. No backup roadmap. No certainty that things would work out. I just knew one thing: if I stayed too comfortable for too long, I'd probably never leave." Starting alone from a small office in Charni Road, Mumbai, CA Nainit built the firm one client relationship at a time — on the principles of clarity, honesty, and genuine care.
"Comfort always scared me more than failure did. So I took the risk. And that risk became Casela Advisors — a firm built not just on technical expertise, but on the belief that every client deserves a CA who truly cares."— CA Nainit Digesh Savla, Founder & Managing Partner
Today, Casela Advisors is a 70+ member full-service CA firm with a 15-year track record of helping businesses navigate India's complex tax and compliance landscape. We serve 2,000+ clients across 16+ industries — delivering practical solutions that translate directly into business growth.

Core Values
The Principles Behind Every File We Handle
Six values that every member of our 70+ team lives by — on every engagement, with every client.
Integrity First
We will never advise tax evasion, misrepresentation, or anything that creates legal risk. Every recommendation is legally sound, ethically grounded, and fully documented — always.
Accuracy & Precision
Strong internal checks, proper documentation, and timely follow-ups help ensure accurate filings and on-time compliance for every single client we serve. Zero errors, zero penalties.
Clear Communication
We communicate in simple language, avoid technical jargon, and ensure every client understands what we're doing and why — so they can make informed financial decisions confidently.
Proactive Advisory
We don't wait for you to ask. We send advance reminders, flag law changes, bring tax planning opportunities to you before deadlines hit — because reactive is never good enough.
Client-First Always
A client-focused approach is not a tagline — it's how every engagement at Casela Advisors is designed. Your compliance, growth, and financial well-being are our only metrics of success.
Updated Knowledge
Tax law changes constantly. Our entire team undergoes mandatory CPE training, attends ICAI seminars, and stays current on GST circulars, budget amendments, and ITAT judgements.
Leadership
Meet CA Nainit Digesh Savla
Founder, Managing Partner, and the driving force behind Casela Advisors' 25-year journey from a one-room office to Mumbai's most trusted CA firm.
CA Nainit Digesh Savla
From Big 4 to Building Mumbai's Best CA Firm
CA Nainit Digesh Savla is a Fellow Chartered Accountant registered with the Institute of Chartered Accountants of India (ICAI). With 25+ years of practice across taxation, audit, GST, and financial advisory, he is one of Mumbai's most respected chartered accountants.
Before founding Casela Advisors, CA Nainit held senior roles at a leading Big 4 firm — gaining deep expertise in corporate taxation, transfer pricing, and multi-jurisdictional compliance. He left this position not out of necessity, but out of a conviction that clients deserved more personalised, proactive, and honest advisory than the large-firm model could provide.
Starting alone from Charni Road, Mumbai, he built the firm one client relationship at a time — on the bedrock of technical precision, ethical practice, and genuine care. Today, Casela Advisors serves 2,000+ clients, employs a 70+ member team, and is rated 5.0★ on Google — a direct reflection of the culture CA Nainit instilled from day one.
