Bio
Dr. Alphonce Khaoya Nabiswa is a Consultant Psychiatrist at Parklands Mindcare Centre and a Clinical Assistant Professor (part-time) in the Department of Medicine at Aga Khan University, Nairobi. He provides outpatient psychiatric care for adolescents and adults across the conditions most commonly seen in private practice in Kenya: depression, anxiety, PTSD, postpartum mood disorders, addiction, sleep, borderline personality, and adolescent mental health.
His clinical specialism is neuropsychiatry and psychopharmacology, with a strong emphasis on evidence-based, patient-centred care. He combines pharmacological expertise with a focus on prevention: exercise, nutrition, sleep, and lifestyle interventions are built into every plan, alongside medication and therapy referrals.
Dr. Nabiswa is also a pioneer of ketamine therapy for treatment-resistant psychiatric conditions in Kenya, having introduced low-dose intravenous ketamine for severe and treatment-resistant cases at Aga Khan University Hospital, Nairobi, in 2019. The specialty programme he established now runs at Parklands Mindcare Centre.
He brings cross-cultural perspective to his practice, having trained as a psychiatrist in South Africa and worked clinically in Australia and Kenya, and is committed to improving mental health outcomes through clinical practice, teaching, and the careful adoption of emerging therapeutic modalities.

His clinical history with ketamine
Dr. Nabiswa's relationship with ketamine spans nearly four decades. He first encountered the drug in the late 1980s as a young medical officer at St. Mary's Hospital, Mumias, a rural Catholic mission hospital in western Kenya, where ketamine was used as the anaesthetic agent for caesarean sections and abdominal surgery. He returned to it in 2015 as a psychiatrist in New South Wales, Australia, treating patients with treatment-resistant depression. After the FDA approved intranasal esketamine in 2019, he became the first Kenyan psychiatrist to offer low-dose ketamine infusions for severe and treatment-resistant cases at Aga Khan University Hospital, Nairobi.
