Specialist in occupational health care

Welcome to Aava

My specialization is occupational medicine and insurance medicine. I am a medical doctor and specialist in occupational health.

I graduated as a doctor in Finland in 1998, specialists in occupational health doctor in 2004. My Ph.D. dissertation related to occupational cancers was completed in 2005.  I have been medical expert for KELA since 2009, I have special qualification in insurance medicine. I am a Finnish citizen.

In the Medical Centre of Aava I work as an occupational health specialist and as an expert in insurance medicine. Working well-being, rehabilitation and retirement solutions are my strengths. I am a member of the Finnish Medical Association.

Occupational health client (my time cannot be booked directly online):

  • Book my call time first (Monday, Wednesday, or Friday), do so also for Health Check
  • I'll call you during the day, most likely between 4pm and 7pm
  • If your matter cannot be fully solved by phone, you will be given a time for appointment in my office+
  • I can't take flu patients to my appointment. Cancel my appointment and seek emergency care if needed if you have any of the following symptoms: fever, cough, myalgia, shortness of breath, headache, toothache, sore throat or rhinitis; if you do not have time to cancel, you should stay at home so I will call you at the appointment and I will try to help you over the phone. Canceling my reception for the above reason will not result in a cancellation bill.

Private Client:

  • Book primarily with me a remote, over-the-phone appointment/ occupational medicine and insurance medicine

I mainly offer help from the point of view of occupational health doctor and insurance expert:

  • Coping at work and in life
  • Medical examinations and chronic diseases (eg hypertension and high cholesterol)
  • Medical rehabilitation (eg rehabilitation provided by KELA)
  • KELA benefits (eg sickness allowance, disability allowances, pensioner care allowances)
  • Vocational rehabilitation (eg re-employment or reintegration measures such as work placements or retraining)

In particular, I hope that my remote appointment will improve your understanding of the principle of insurance medicine and thus improve the outcome of your cooperation with insurance companies.
