Professional Counselling through divorce & separation



Welcome to One Health Therapy

One Health Therapy was founded by Dr. Ronan O' Neill, a specialist in divorce and separation and Parental Alienation, after hearing the stories of so many parents, guardians, grandparents, and other close family relatives struggling to avoid high conflict separations. The absence of any meaningful direct access and contact with ones children can be painful; this scenario can often occur before, during and after a separation or divorce. The children's stories are also surreal bringing sorrow, anguish and debilitating anxiety in their lives. The psychological impact of such an ordeal can result in many mental health issues for both parents and children which One Health Therapy aim to provide.

What is Parental Alienation ?

Parental Alienation is the unwarranted and often the complete illogical rejection of a parent by a child where there was a prior normal caring and loving relationship with that child. More often than not, it occurs in high-conflict relationship separations and divorces. It can be the action of the child's illogical aligning with the resident parent and rejecting the non-resident parent throughout the entire separation/divorce period and beyond.

Working with Alienated Targeted Parents & their Children

First Step in recognizing it


At One Health Therapy, our first task is to identify your family dynamics and see if you are a parent who has been the target of PA. Is your case either mild, moderate or severe alienation where your child unjustifiably rejects you and the other parent intentionally or not targets you. 

Acknowledgement of your pain


At One Health Therapy, we acknowledge your loss and your pain for missing and not seeing your child. It can be a very sad experience and you may feel shame, grief, loss, rage, guilt & dismay at the way you are being treated. Many professionals don't spot the problem early-on, and this can potentially create further problems to yours and your child's health. 

Identifying your main concerns


If you are a targeted parent who has been the victim of alienation, then it is likely you may have some issues to discuss, especially if you have not seen your child over a prolonged period of time. The negative mental health impact on you can be extensive if you have been struggling unsuccessfully to keep contact and access to your child,. Many alienated parents find that it can be truly exhausting on them, impacting their whole lives. 

Awareness & Empowerment


In so many cases, the targeted parent cannot understand why many mental health and legal professionals completely do not see whats really going on. Even other extended family members do not fully comprehend your struggle to see your child.. Understanding is empowering ! 

Long-term effects of alienation


It is important to talk and get help from an expert on parental alienation so you maintain positive resilience to allow you successfully get back in contact with your child. The long-term effects of Parental Alienation can be  extremely harmful to a child and such effects are multi-generational, which is why it is even more crucial to seek Counseling and guidance today ! 

Psychological reports


At One Health Therapy we can provide some support to help you on the main issues during separation/divorce when children are involved.. Please note ! such services and guidance  are not considered therapy or counselling. The provision of guidance and services on Parental Alienation can involve Court Section 47 reports and other legal required assessments such as Parental assessments.
