“𝑩𝒆𝒊𝒏𝒈 𝒂 𝒅𝒐𝒄𝒕𝒐𝒓, 𝒚𝒐𝒖’𝒍𝒍 𝒖𝒑𝒍𝒐𝒂𝒅 𝒗𝒊𝒅𝒆𝒐𝒔 𝒐𝒏 𝒀𝒐𝒖𝑻𝒖𝒃𝒆?”

These were the kind of comments I used to hear when I first started uploading videos on my YouTube channel.

Being awarded as the “𝐌𝐞𝐝 𝐘𝐨𝐮𝐓𝐮𝐛𝐞𝐫 𝐨𝐟 𝐭𝐡𝐞 𝐘𝐞𝐚𝐫” at the Medical Creative Conclave 2025 (MCC) is a humbling reminder that 𝒆𝒗𝒆𝒓𝒚 𝒅𝒓𝒆𝒂𝒎 𝒊𝒔 𝒘𝒐𝒓𝒕𝒉 𝒄𝒉𝒂𝒔𝒊𝒏𝒈 𝒘𝒉𝒆𝒏 𝒕𝒉𝒆 𝒑𝒖𝒓𝒑𝒐𝒔𝒆 𝒊𝒔 𝒔𝒕𝒓𝒐𝒏𝒈.

What started as just one dream- to spread medical knowledge across the world- has today grown into a global community of 680,000 𝐬𝐮𝐛𝐬𝐜𝐫𝐢𝐛𝐞𝐫𝐬 𝐚𝐧𝐝 𝐨𝐯𝐞𝐫 45 𝐦𝐢𝐥𝐥𝐢𝐨𝐧 𝐯𝐢𝐞𝐰𝐬. This dream was first sparked by my wife, 𝐃𝐫. 𝐒𝐡𝐫𝐮𝐭𝐢 𝐌𝐚𝐥𝐢𝐤, whose idea inspired us to put our hearts into creating content that simplifies complex medical concepts.

From ECGs and chest X-rays to key emergency topics, our aim has always been 𝘵𝘰 𝘴𝘪𝘮𝘱𝘭𝘪𝘧𝘺 𝘮𝘦𝘥𝘪𝘤𝘢𝘭 𝘤𝘰𝘯𝘥𝘪𝘵𝘪𝘰𝘯𝘴 𝘢𝘯𝘥 𝘵𝘩𝘦 𝘢𝘱𝘱𝘳𝘰𝘢𝘤𝘩 𝘵𝘰 𝘮𝘢𝘯𝘢𝘨𝘦 𝘢 𝘱𝘢𝘵𝘪𝘦𝘯𝘵, 𝘱𝘳𝘦𝘴𝘦𝘯𝘵 𝘨𝘶𝘪𝘥𝘦𝘭𝘪𝘯𝘦𝘴-𝘣𝘢𝘴𝘦𝘥 𝘵𝘳𝘦𝘢𝘵𝘮𝘦𝘯𝘵, 𝘢𝘯𝘥 𝘩𝘦𝘭𝘱 𝘩𝘦𝘢𝘭𝘵𝘩𝘤𝘢𝘳𝘦 𝘱𝘳𝘰𝘧𝘦𝘴𝘴𝘪𝘰𝘯𝘢𝘭𝘴 𝘮𝘢𝘯𝘢𝘨𝘦 𝘪𝘯 𝘵𝘩𝘦 𝘣𝘦𝘴𝘵 𝘱𝘰𝘴𝘴𝘪𝘣𝘭𝘦 𝘸𝘢𝘺- making it easier for them to apply it in clinical practice and ultimately save more lives.

Our vision has always been to train healthcare professionals who are managing countless patients every day. 𝐓𝐡𝐞 𝐢𝐦𝐩𝐚𝐜𝐭 𝐢𝐬 𝐭𝐡𝐞𝐫𝐞𝐟𝐨𝐫𝐞 𝐦𝐮𝐥𝐭𝐢𝐟𝐨𝐥𝐝- 𝐛𝐲 𝐞𝐦𝐩𝐨𝐰𝐞𝐫𝐢𝐧𝐠 𝐝𝐨𝐜𝐭𝐨𝐫𝐬, 𝐧𝐮𝐫𝐬𝐞𝐬, 𝐚𝐧𝐝 𝐩𝐚𝐫𝐚𝐦𝐞𝐝𝐢𝐜𝐬 𝐰𝐢𝐭𝐡 𝐩𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥, 𝐞𝐚𝐬𝐲-𝐭𝐨-𝐚𝐩𝐩𝐥𝐲 𝐤𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞, 𝐰𝐞 𝐢𝐧𝐝𝐢𝐫𝐞𝐜𝐭𝐥𝐲 𝐭𝐨𝐮𝐜𝐡 𝐦𝐢𝐥𝐥𝐢𝐨𝐧𝐬 𝐨𝐟 𝐩𝐚𝐭𝐢𝐞𝐧𝐭𝐬 𝐚𝐧𝐝 𝐡𝐞𝐥𝐩 𝐢𝐦𝐩𝐫𝐨𝐯𝐞 𝐨𝐮𝐭𝐜𝐨𝐦𝐞𝐬 𝐨𝐧 𝐚 𝐦𝐮𝐜𝐡 𝐥𝐚𝐫𝐠𝐞𝐫 𝐬𝐜𝐚𝐥𝐞.

By God’s grace and with the support of all of you, this journey has become so much more than just videos- it has created an ever-growing ripple of learning and patient care.

What made the event even more special was meeting so many young Doctors who shared that I inspired them to start their own journey of creating content on social media. It feels incredible to know that the 𝐢𝐧𝐬𝐩𝐢𝐫𝐚𝐭𝐢𝐨𝐧 𝐠𝐨𝐞𝐬 𝐛𝐞𝐲𝐨𝐧𝐝 𝐬𝐚𝐯𝐢𝐧𝐠 𝐥𝐢𝐯𝐞𝐬- it’s also about encouraging others to discover their hidden talents and take that bold step into content creation.

A heartfelt thank you to everyone who has been a part of this journey- special thanks to Dr Vishal Gabale for inviting me to the event, to my wife Dr. Shruti Malik for her unwavering belief in this vision, and to my parents whose constant support and blessings have been my greatest strength.

This is just the beginning- we will keep working to impact and inspire even more people in the years to come.
