About David

David Kerr is a board-certified family nurse practitioner and co-founder of Dajjesa, a hormone clinic in Tucson, Arizona. He specializes in testosterone replacement therapy (TRT) for men, bioidentical hormone replacement therapy (HRT) for women, and thyroid optimization.

David founded Dajjesa with his wife, Jannine Kerr, LPN, to offer the kind of care they felt was missing: unhurried visits, clear explanations, and ongoing support instead of a quick prescription. He earned his Master's from Grand Canyon University and has completed specialized training in hormone replacement therapy.

My Approach

Too many people are told their labs are "normal" while they still feel exhausted, foggy and unlike themselves. I believe hormone care should start with listening, and that no two patients should get the same plan by default.

Time to get it right

Every new patient receives a comprehensive lab panel and a full consultation. We go through your symptoms, history and goals before deciding anything.

Bioidentical hormones, individually dosed

I use bioidentical hormones from licensed compounding pharmacies, dosed around how you feel as well as what your labs show.

Ongoing, concierge-level care

We recheck labs and meet every three months, adjust as your body responds, and you can reach our team when questions come up.
