    Optimising Your Brain Health and Wellness Lincoln Recruitment Specialists

My guest today is Dr. Krystal Culler.


Dr. Krystal Culler, DBH, M.A, is the Founder of Your Brain Health Matters, a consulting business that offers a variety of brain health and memory care services to senior care professionals and businesses to make their projects and initiatives thrive. Through the Virtual Brain Health Centre she educates brain wellness to individuals online.


As a Doctor of Behavioral Health, her areas of expertise are in healthy aging, brain health, memory care, and dementia risk reduction. Krystal is also a Senior Atlantic Fellow for Equity in Brain Health with the Global Brain Health Institute.


After an isolated seizure event at graduate school, her career path shifted from a traditional academic track to a healthcare practitioner role. Central to her doctoral training is the design of cost-effective health approaches to treat chronic and comorbid conditions while addressing the social impacts on health. 


Krystal helps translate the latest research on brain health through practical daily approaches and community-based programs. ​Her work lies between the intersection of brain health and wellness, and the health/ ageing services sectors. As it’s clear in the interview, our brain health is a priority, not an option.


It’s a pleasure to have Krystal join us in this episode as we cover lifestyle practises, what to consider when ageing and practising lifelong learning.
