Existing patient ready to make next medication order w/ Dr Sivam (CBD and/or TRT order)

$215

A compassionate, patient-focused clinician with a strong foundation in evidence-based medicine, Dr. Sivam has a special interest in hormone optimisation and medical cannabis therapeutics. Originally from Singapore and medically trained in Australia at Australian National University, she combines an international perspective with a strong understanding of Australian clinical practice.

She has extensive experience in testosterone replacement therapy (TRT) and medical cannabis care, supporting patients with sleep disturbances, chronic pain, injury recovery, anxiety, and overall wellbeing. Her approach is holistic and pragmatic — focused not only on symptom relief, but on improving long-term function, vitality, and quality of life through individualised, carefully monitored treatment plans.

As a devoted mother, Dr. Sivam appreciates the real-world demands patients face and understands that many seek care to maintain energy, presence, and engagement with their families and careers as they age. She collaborates closely with colleague, Dr. Chalik to ensure continuity of care and thorough case review, creating a supportive pathway where patients feel informed, heard, and confident in their treatment.

Nathan is hands down the best GP I’ve ever worked with. As a competitive bodybuilder, it’s almost impossible to find a doctor who actually understands the demands of high-level training, performance, and health — but Nathan doesn’t just understand it, he excels in it.

His knowledge, attention to detail, and ability to tailor everything to the individual is on another level. He provides a level of care and service that you simply won’t find anywhere else. You can tell he genuinely cares about getting the best outcome for his patients, not just ticking boxes.

If you’re serious about your health, performance, or just want a doctor who actually knows what they’re doing, I couldn’t recommend Nathan highly enough.
