About the PHA UK

Who we are

The Pulmonary Hypertension Association (PHA UK) is run by a small group of committed individuals. These include office staff who are trained and experienced in dealing with people affected by pulmonary hypertension (PH). They deal with a range of projects and activities on a daily basis including:

  • dealing with incoming donations
  • sending out membership packs and relevant literature
  • organising events such as the PHA UK conference, family weekend and meetings for various medical professionals
  • collating stories for our quarterly magazine (emphasis)
  • dealing with the ordering and despatching of PHA UK merchandise
  • managing fundraising events and entrants into events such as the London Marathon, BUPA 10k run and Just Walk
  • applying for grants with charitable trusts
  • mailing important information and news to PHA UK members.

The office is continuing to develop to suit the needs of our supporters and we look forward to speaking to you if you have any queries or feedback that we can help you with. Unfortunately we are not able to offer medical advice and we would always recommend that you speak to your PH specialist centre, consultant or GP.
