Hello, I’m Tiga-Rose Nercessian.
My pronouns are she/her.
I’m a multi-certified Sex & Relationship Psychotherapist, qualified general Counsellor, with an Advanced Diploma in Relationship Therapy. I’m also a trainer and academic researcher. I have been working in this field since 2015.
As well as extensive training, I have an innate awareness of what most people don’t look at, either because they don’t want to or can’t bring themselves to do so alone.
When we work together, it’s important that you feel heard, held, seen, and safe. My aim is to support and empower you to have happier, healthier, and more fulfilling relationships with yourself and others – whatever that looks like for you.
Areas Of Expertise
Sexual functioning issues we can address include: pain during sex, loss of desire, erectile dysfunction, premature ejaculation, and an inability to achieve orgasm.
Relationship issues we can work on include: loss of intimacy and desire, difficulty communicating, arguing, and drifting apart.
Personal issues that impact sex and relationships include: questioning your sexuality, exploring your gender, introducing kink and BDSM, and opening up a relationship.
I'm now in a very intense and fulfilling relationship with one man and pregnant with another!"

I channelled what you taught me about communication and got super specific about what works for me. Super fun!"
