Quest Ketamine Therapies — Ketamine Clinic in Issaquah, WA

Very grateful for Mitch & Haley and Nathan, they walked me through the whole process and answered all the questions I had. And thankfully they accepted my insurance. Changed my life and gave me the boost I needed to get out of a bad mental rut and have been improving more and more. Will forever be grateful, the experience itself is awesome and the playlist options are perfect. The office is also very nice and you feel safe to go inwards. Highly recommend!!

If I could rate this place 10 stars I would. Mitch and Hayley are literally the best people. They genuinely care about their patients and want to help them. They helped me so much. I had so much going on that didn’t respond to any other treatment before coming here including pretty bad ptsd and bpd. Now, I am feeling the best I have in over 4 years. I highly recommend this place if your thinking of doing ketamine or any other service they offer:)

TL;DR: I honestly believe that anyone would benefit from Quest’s services— go for it. If I could give them 10 stars, I would. I can’t say enough about Mitch, Hayley, Nathan—and my own ketamine “journey,” as Mitch calls it. Life has handed me multiple… what I’ll euphemistically call “growth opportunities” that left me with PTSD and attachment issues. Years of therapy helped, but I hit a wall. That’s when I decided to try ketamine as a supplement—an infusion at Quest followed by a therapy session. I feared it would be awkward, possibly even nightmare-ish, but the experience surprised me in the best possible way. Nathan patiently walked my partner and me through the process, answered all our questions, and handled insurance. Mitch and Hayley, meanwhile, strike the perfect balance of professional and relatable. In their care, I felt safe and welcome. The ketamine experience itself was almost spiritual—like an advanced form of meditation. It was profoundly insightful and healing, and the addition of NAD+ has given me so much more energy. I’m deeply grateful to Quest for helping me move forward. I’ve already recommended them to my partner and several of my friends.

I can’t speak highly enough of my experience at Quest Ketamine Therapies. From the moment I walked in, I felt supported, respected, and genuinely cared for. Mitch and Hayley were absolutely wonderful — compassionate, attentive, and incredibly knowledgeable. They made my treatment feel safe, personalized, and truly healing. The experience was transformative, and I’m so grateful for the care I received. I would wholeheartedly recommend Quest to anyone exploring this path. 10/10

I cannot speak highly of Dr. Mitch and the services he provides. He genuinely cares--not only about his patients, but you can feel the amount of love and care they put into their office space. It's a whole vibe. The space feels calm, and you are greeted with kindness and care. They truly go above and beyond to make you feel safe & cared for. Not only in your actual session, but with your overrall progress outside of the room. I 10/10 recommend QKT. (They also have the BEST candy selection:)). I will miss you both, Dr. Mitch & Hayley! Thank you both so much for all you've done for me.

Not affordable if you live paycheck to paycheck. No flexible payment plans offered, financing is subject to credit check.

This has changed my life. I believe everyone should try this. This office is first class. I felt heard and comfortable and they know what they are doing in fact if I ever have to go in for surgery again I'm going to request Mitch be my Anesthesiologist. Him and his wife are a amazing team. I look forward to future sessions. Thank you guus.

I can’t overstate the impact Quest has had on my life. From the medicine itself to the warmth, kindness, and intentionality of the team, I’ve benefited beyond words from this treatment. I’d give many more stars if I could. Deeply grateful to have found this clinic.

My sessions at quest have made a serious positive impact on my life. They made me feel safe and relaxed on my journey of self discovery.
