Client Stories

Hear from our community

“I have been going to see Jeremiah and Yeondo for massage regularly for the past several years. They are both excellent massage therapists. I have had prenatal massage (they helped me through debilitating back pain during both my pregnancies), cupping, deep tissue, and Thai massage...all wonderful! Love this spa! I can't recommend them enough!”

“I really loved the whole experience and I feel like they were all so welcoming and kind. I got a facial from Kimberly and absolutely loved it and I would 100% recommend her. Overall, I had such a fantastic and relaxing experience and I would do it again no question.”

FAQ

Frequently Asked Questions

What do I need to know about online booking?

Online booking is a great way to schedule an appointment with us. We are therapist owned and run, and we don’t always have a receptionist in the office. To avoid phone tag, or if you are craving a massage or facial at 2 in the morning, just click on our online booking link here. Please note that we may call you after you book to slightly shift your start time. This is to maximize scheduling efficiency for our therapists.

For those who aren’t sure what to choose, the Signature massage or facial is a good place to start. For IV therapy in Kirkland—including hydration and NAD+ treatments—choose the New Client Special or Essential Drip under the Wellness tab.

What is IV hydration therapy?

IV (intravenous) therapy delivers fluids, electrolytes, vitamins and other nutrients directly into your bloodstream through a small catheter placed in a vein. This method ensures rapid hydration and maximum absorption—much faster and more effective than drinking fluids alone. Many clients in Kirkland and on the Eastside choose IV therapy for recovery, immunity, and energy; digestive tract issues are common, and IV therapy bypasses the gut so nutrients reach cells directly.

What happens during an IV appointment?

Once you schedule, you will be contacted by our medical director to complete a brief health intake. This will determine whether you are a good candidate for IV therapy, and any potential contraindications. When you arrive at our spa, you will sign a consent and our registered nurse will help you select the right formulation and answer any questions that you might have. You will be welcomed into a comfortable chair and made at home. Your vitals will be taken, an IV will be started on your arm, and your personalized drip will be started. Sessions typically last about 45–60 minutes (some drips may take longer, such as NAD+).

Who administers the IV? Is it safe?

A medical professional such as a Registered Nurse or Nurse Practitioner will be administering your treatment. They follow aseptic technique and strict medical protocols to ensure each client’s safety and well-being.

What’s in a drip?

Formulations vary by goal, but common options include normal saline, electrolytes, immune support (vitamin C, zinc), energy blends (B-complex), recovery/performance minerals (magnesium), and antioxidants like glutathione—sourced through reputable pharmacies. Some specialty formulations also include anti-nausea or anti-inflammatory medications. Your provider will tailor ingredients and dosing to your intake, goals, and health history. See some of our IV options here.

How quickly will I feel results, and how long do they last?

Many people feel benefits—like renewed hydration or energy—almost immediately. Depending on the formulation, you may also experience a reduction in pain, nausea, and cold/flu symptoms. Effects can last from several days to a week, influenced by your overall health, sleep, stress, and lifestyle.

How often should I get a drip?

It depends on your goals and health status. Some come when needed, such before or after illness or travel, or during particularly busy or stressful weeks. Others prefer a more regular schedule. We’ll help create a safe, personalized plan just for you. Click here to learn about our membership options.
