Dr Grant Dalziel

MBBCh (Wits) , FCFP

Grant studied medicine at Wits Medical School, after which he completed his Internship at Coronation Hospital then joined the Defence Force. Here he did his obligatory military service providing Medical care to the family and staff of the Navy in Simonstown. This is where his love for General & Family Practice began.


“I am still committed to the practice of good family medicine and have a particular interest in Dermatology having studied this over many years under the guidance of some of the top Dermatologists in the country. I have become somewhat of an expert in removing small skin lesions and blemishes having also gained experience from a number of prominent Plastic Surgeons. A further area of interest is my knowledge and understanding of Alcoholism and its impact on the family.”

Grant acts as an expert witness in Medico Legal cases on an ongoing basis which is testament to his wealth of knowledge and experience and the high level of esteem bestowed on him by his medical colleagues and other professionals.

Dr Peta Lynn Jearey

MBBCh (Wits) DipPEC SA, FCFP, BMus (Wits) LTCL. National Diploma in Diagnostic Radiography

Dr Peta Lynn Jearey qualified from the University of the Witwatersrand and has worked as a specialist Family Physician for over 30 years.

I was somewhat different from my peers at Medical School. I had already spent over 8 years in tertiary education since leaving school when I embarked on my medical career. I knew when I started that I wanted to go into Family Medicine. After I graduated I started immediately to further my knowledge and skills in the wonderful and fulfilling area of Medicine.

I achieved the Fellowship in Family Medicine in 2007, and completed an intensive course in Emergency Medicine. In 1993, I received a Diploma in Primary Emergency Care.

I am seriously passionate about Family Health and the longer I remain in practice, the more convinced I am that the more holistically we view Health and Wellness, the more likely we are to achieve it. I believe that we should empower patients to take ownership of their health and guide them in this pursuit rather than merely providing prescriptions and instructions.

Dr Jearey is a Family Medicine Preceptor at the Department of Family Medicine, Department of Health Sciences at Wits Medical School, and is passionate about teaching and encouraging young doctors to enter this field.

She is also a Menopause Practitioner and a member of the North American Menopause Society,  the South African Menopause Society and the British Menopause Society. She regularly attends continuing medical education in order to stay relevant and up to date in the field of Women’s Health. In addition, she is the doctor in charge of the Sandton Travel Clinic and a certified Travel Health Practitioner having completed the requirement for the Certificate in Competency in Travel Medicine at the University of the Witwatersrand department of Public Health in 2009. Her qualifications also include a Distinction in Diabetes Management with CDE.

She enjoys all aspects of Family Medicine but her particular areas of interest include:

  • Women’s Health  including Menopause & Adolescent gynaecology
  • Cardiovascular Disease in Women
  • Anxiety and Depression
  • Travel Medicine
  • Child Health
  • Dermatology
  • Diabetes and Diseases of Lifestyle
