Tom is a very compassionate, knowledgeable guy and generous with his time, he put a detailed plan together and follow up e-mail that I can refer to when needed. To combat anxiety, I am currently implementing changes to my diet based on his recommendations and am hopeful they will have a positive impact over the coming weeks. Highly recommended!

I have to say Tom is both professional and personable. I have been to see many natural practitioners in the past in Australia but coming home to Ireland was great knowing I had found Tom to see. He is attentive, thorough and does not leave a stone unturned.
I cannot recommend Tom and his knowledge enough.

Tom is extremely knowledgeable and compassionate , he made me feel completely at ease and I felt like I was visiting with an old friend. Tom provides not only advice on herbs but also practical advise on diet and life style. I left feeling more relaxed and positive that I was on the right track to get my health back to where it should be. I cannot recommend Tom enough.
