Dr Sukumar Rajendra: Leading psychiatrist and father-of-two suddenly dies aged 48 - as his final selfless act is revealed

Devastated friends and family of a psychiatrist who suffered a fatal stroke aged just 48 have revealed his last act was donating organs to those in need. 

Dr Sukumar Rajendran died last week surrounded by his family and loved ones after desperate attempts to save him failed.

The leading medic was remembered as an 'intelligent, thoughtful, reliable, and compassionate man' who was held in the 'highest regard' among colleagues.

He ran the Mind Oasis clinic in Strathfield in Sydney's west where he specialised in treating adult ADHD, mood disorder and anxiety.

It followed years of working at Concord Repatriation General Hospital and Royal Prince Alfred Hospital in consultation liaison and drug and alcohol service roles 

The celebrated psychiatrist was also known as a dedicated family man after marrying wife Katy Baker six years ago, and having two sons Air, four, and Jai, two. 

His friend and colleague of over 15 years, Charles Chan, revealed in a GoFundMe for the family that Dr Rajendran donated his organs after his death.

'In his final moments, he continued to show his selflessness by donating his organs, giving the gift of life to several individuals in need,' Mr Chan wrote. 

The pair had worked together at the same clinic for the past four yearsand he paid tribute to the medic in the appeal fund post. 

'I can tell you firsthand how committed he was to staying up-to-date with the best practices in our field,' Mr Chan wrote. 

Known by his nickname Suke, Mr Chan added Dr Rajendran was more than an amazing psychiatrist' but a 'wonderful friend, dedicated professional, and a true pillar of our community'.

The fundraising page has already received more than $13,000 in just a day as other friends of Dr Rajendran posted tributes to the late doctor.

One of his friends from medical school, Kevin Chua, said one of his 'favourite people in the world is no more' in a heartfelt post to social media.

Dr Chua said his late friend 'always made people laugh and was comfortable being laughed at' and helped introduce him to his now wife.

'We both cried when he told us he was marrying Kate Baker, we cried again when he said he was going to be a father and cried again when he said he was going to be a father a second time,' he wrote in a post to Facebook.

'And now we cry because we will not be able to laugh with him over his silly jokes or be able to hear his pearls of wisdom.

'I’m so glad we got a chance to see him at the very end. Suks, you are sorely missed.'

A memorial service for Dr Rajendran will be held on Thursday.
