Licensed Psychologist (PSY17130)

My Practice & Approach

My Practice

I believe in working with the whole person, not deficits and disease.  I work with you, and with your permission, collaborate with your care providers to insure you obtain the highest level of service.  Therapy sessions typically run 45 minutes and are interactive.  I make home visits if you cannot come to my office.  

My Treatment Focus

I focus my practice exclusively on aging adults and their issues.  Working with elders requires that I have a broad spectrum of knowledge and experience including psycho-pharmacology, nutrition, pain management, and cognitive evaluation in addition to the more traditional talk therapies.  

Insurance and Payment

I take traditional Medicare and some Medicare Advantage plans on a case-by-case basis.  If you are not Medicare eligible, I will provide services on a fee-for-service basis. 

Therapy with Dr. Flett

Cognitive Health

Keeping our minds challenged, engaged, and in good condition over the lifespan requires  stress management strategies, knowing how to manage pain effectively, and being aware of our thoughts, feelings, beliefs, and behaviors. I'll guide you in finding the best way to stay cognitively healthy as you age.

Depression & Anxiety

These moods are NOT a part of aging.  If you are feeling anxious, sad, having sleep problems, and not finding life fulfilling, you may benefit from talking to me about what's going on with you.  I'll systematically assess your functioning and help you make healthy decisions to address these challenges.

Quality of Life

Purpose and meaning become more important at we age.  Finding ways to stay useful and active, even as things change, is essential in having a high quality of life at any age.  Loss of functioning often means a lower quality of life.  I'll partner with you in exploring how you want to live your later years and help you create that vision.
