I'm an occupational therapist with a strong background in stroke recovery. I also worked as a massage therapist for many years supporting stroke survivors with shoulder and back pain. As a clinical navigator with Kandu, I enjoy connecting with survivors and carepartners with a heart-first approach to foster empowerment and tackle challenges to recovery. I cherish each small win with survivors and carepartners, be it connecting them with a resource or just being the person that has the time to listen, I'm here for it all! When I'm not connecting with my fabulous colleagues at Kandu, I am sure to be found in or around bodies of water, laughing with my toddler and husband about something silly.

I am a licensed clinical social worker with a strong background in advocacy and mental health. As a clinical navigator with Kandu, I enjoy working with Survivors and Care Partners as they traverse and process their new experiences and realities. I am grateful to be with them as they return to (or discover new) activities that bring them meaning, joy, and value. We are here to provide education, resources, and support, as well as someone who will not only hear you, but who will actively listen.  My favorite thing about working at Kandu is that we encourage our Survivors to set their own goals and take charge of their recovery and lives.  When I am not working I can be found walking my puppy Augie, spending time with my friends, or watching sports.
