Our Mission Is to Provide a Personal, Professional & Honest Approach to Health Care

Our philosophy about YOUR care, focuses on the holistic care we can provide to each and every one of you. As Nurse Practitioners, we strive to focus on the whole person, not just what’s on the surface.


Experienced Nurse Practitioners

Tammy was a nurse for 19 years before becoming a board certified Family Nurse Practitioner in 2019 to be able to provide more and better services to her patients. Aisha graduated from Purdue University Global in March of 2023. She is board certified as a Family Nurse Practitioner by the American Association of Nurse Practitioners holding licenses in Idaho and Washington.


Professional & Friendly Staff

The people who work in our office understand health issues and want to help in any way they can.


We accept most insurances.

Our Services

We provide a full range of primary, acute, and specialty health care services, from the simple cuts and scrapes to diagnosing and treating acute and chronic conditions such as diabetes, high blood pressure, infections, and more serious injuries.

We partner with Interpath Laboratories to provide processing of laboratory tests with results normally within 24 hours. If results are needed sooner we also have access to Pathologists  Regional Laboratory. Lab work can be drawn in the clinic without having to go to the lab for your blood draws saving you both time and a trip!

Primary Care

A Nurse Practitioner is an ideal choice for your primary care giver because what set NP’s apart from other health care providers is their unique emphasis on the health and well-being of the whole person. We provide primary care services for patients ranging from infants to seniors. We conduct well checks, screen for disease symptoms, administer treatments, and order tests under the premise of enhancing a patient’s overall well-being.

Urgent Care

We treat a wide range of acute conditions including infections, allergies, skin conditions, cold and flu symptoms, strep throat and minor injuries and wounds.

Women's Health

Women have many unique health concerns — menstrual cycles, pregnancy, birth control, menopause — and that’s just the beginning.

Men's Health

Men are assailed by the diseases that can affect anyone—heart disease, stroke, diabetes, cancer, depression… But they also have unique issues such as prostate cancer and benign prostate enlargement.


Technically speaking, geriatric care is the medical care of older or elderly people. The scope of the care includes not just the medical needs, but also the psychological and social needs of seniors. More than ever before, geriatric care encompasses a holistic approach to coping with aging and its effects.


Pediatrics is a multifaceted specialty that encompasses children’s physical, psychosocial, developmental, and mental health. Pediatric care may begin periconceptionally and continues through gestation, infancy, childhood, adolescence, and young adulthood.


Many medical issues can be diagnosed and treatments assigned over the phone, or even better, using a face-to-face remote internet video meeting using a service like Zoom. Call us to see if your particular issue may be one that can be handled in this manner.

House Calls

There are times telemedicine is not possible. We strive to make sure health care is accessible in these cases as well. If you can’t come to Tammy’s office, she will come to you! Call to see if this could be an option for you.

Better and Accessible Health Care is Our Mission
