Our Practice Manager

Rhonda Ward

Rhonda has an extensive background of working in Adult Social Care in London, Wiltshire and Kent. Her roles have included managing and providing services to adults with a Learning Disability, Autism and those with a Sensory Loss.

Rhonda works with the GP Partners and other members of the The Porch team to ensure they continue to provide the care and services our patients need. She is always looking for ways to improve and develop the service and support the team at The Porch. Rhonda also works closely with the other four GP surgeries within our Primary Care Network.

Our Administration Team

Our Administrative, Reception and Secretarial staff work behind the scenes and at the front desk to ensure that the practice runs efficiently and provides the best possible patient experience.


The Porch Surgery has been a training practice for General Practice Registrars for many years. A Registrar is a qualified Doctor who has completed some or all of their hospital training and is now working in General Practice. As part of their training they may see a patient with another doctor sitting in and occasionally they may video a surgery, but always with the patients consent.

Dr Davies, Dr Swallow and Dr Watson are GP Trainers.  However, all the doctors and the Primary Care Team are involved in training.

Social Workers

The Department of Adult and Community Services (DACS), formerly Social Services, provides help, support and care to adults in need in Wiltshire.

How do I get help?

You can get help by contacting the Adult and Community Services Social Care Helpdesk on 0300 456 0111.

You can also ask someone else to make contact on your behalf.

Outside of office hours contact the Emergency Duty Service on 0845 6070888.

The National Health Service (NHS) and Community Care Act requires local Social and Health Services to ensure that support and care is provided to those in greatest need.

As the Department of Adult and Community Services receive more requests for help than there is available funding, we have to decide:

1. Who should get a service.

2. In what order of priority.

3. How services can best be provided.

4. Whether we will provide the service ourselves or suggest another more appropriate organisation.

This is to ensure that people in greatest need will get most help.

How do we decide who should get a service?

Services for Users

When a person asks us for help, we make an assessment. This means that we talk to you to find out more about your situation and your care needs. Your need for services may be due to physical disability or impairment, mental health problems or environmental or social factors. The more complex you needs, the more detailed your assessment will need to be.

Services for Carers

If you are a carer and provide substantial and regular amounts of care to the person you look after, you are eligible for an assessment of your own care needs in relation to the person(s) you care for. As a carer, you may be able to access Services provided through the Carers Special Grant.

If, outside of your role as a carer, you meet the Eligibility Criteria, you are entitled to receive services in your own right.

Who is eligible for an assessment?

You are normally eligible for an assessment if you:

  • Have a physical impairment
  • Have a sensory loss
  • Have a terminal illness
  • Are developing confusion/dementia
  • Are frail
  • Are vulnerable to the risk of neglect or abuse
  • Have a learning disability
  • Have a severe mental illness
  • Are a carer
