About me

I come from Northern Spain (Basque Country) and have lived in Clapham for 30 odd years where I work as a sex therapist at the Clapham Common Clinic.

Whether you come with your partner or alone; if you are gay or straight or whether you are married or single I aim to offer a safe and confidential setting in which to explore your sexual or relationship difficulties.

I work in a short, sharp, direct and intensive way giving you lots of home work so we can tackle and resolve the problems quickly and effectively.

Seeing me will help you see your situation from a completely different viewpoint and to help you understand your problem better. I will ask questions and help you find out if there are any emotional or physical reasons behind your problem. I will also give you exercises and tasks you can do in your own time. You'll never be asked to undertake sexual tasks in a session.

I specialise in:

  • Vaginismus
  • Erectile dysfunction
  • Premature ejaculation
  • Anorgasmia
  • Lack of desire
  • Issues with intimacy
  • Child sexual abuse
  • Trans cultural relationships
  • Body imagines
  • Problems after obstetrics and gynaecological surgery
  • TOP/Abortion

Training, qualifications & experience

I am qualified as a medical doctor as well as a sex-therapist and relationship counsellor. My medical work is as a Community Gynaecologist and Family Planning (awarded a fellowship of the faculty of Reproductive & Sexual Health). My sex therapy work stems from the problems I kept on seeing in my medical work. I studied sex therapy at St Georges Hospital London.
I have the diploma for counselling supervision.
I am a member of COSRT, previously known as BASRT and UKCP.
