Listen First
Health concerns deserve enough time for the patient to explain what has changed, what has already been tried, and what questions remain.

Medicine works better when the physician has time to listen.
IASIS was designed to create more space for thoughtful conversations, clearer explanations, preventive planning, and follow-up that does not end when the appointment does.
Why IASIS Was Created
A Different Response to Rushed Primary Care
Many adults struggle with long waits for appointments, short visits, rotating providers, and unanswered questions after testing or specialist care. Those conditions make it harder for patients to feel known and harder for physicians to connect changes across time.
IASIS Boutique Health was created around a different structure. By caring for a smaller membership panel, Dr. Karanastasis can offer longer appointments, same-day or next-day member availability, direct communication, and ongoing adult medical care from one physician.
The goal is not simply convenience. It is a clearer, more continuous primary care relationship that supports prevention, timely evaluation, medication review, chronic condition management, and informed decisions.
Our Care Philosophy
What Guides the IASIS Patient Experience
Every part of the practice is built around a few simple principles that become difficult to maintain in high-volume primary care.
Connect the Details
Symptoms, medications, laboratory trends, family history, specialists, and risk factors should be considered as parts of one health story.
Explain Clearly
Patients should understand what results mean, what options exist, and why a particular next step may be recommended.
Plan Ahead
Preventive care, annual health planning, and risk discussions help patients address more than the concern that brought them in today.
Follow Through
Ongoing monitoring and result review help ensure that important changes are not treated as isolated events.
Stay Accessible
Direct communication and timely member appointments make it easier to ask questions and address suitable concerns sooner.
