Kaylinne Chang

I feel incredibly fortunate to have found her. Being under her care truly feels like a blessing, and I don’t say that lightly. She is one of those rare healthcare providers who is not only exceptionally knowledgeable and intelligent, but also genuinely kind, compassionate, and understanding. From the very beginning, she made me feel comfortable and truly heard. I am also a healthcare clinician so it is a bit difficult for me to openly talk about my health. She takes the time to listen, asks thoughtful questions, and looks at the whole person rather than simply focusing on symptoms. What makes her especially remarkable is how much she genuinely cares. I trust her wholeheartedly and am so grateful to have her guiding me on my health journey. I cannot recommend her highly enough.

Chip is the most intelligent functional medicine provider I have ever spoken to. She takes time to really deep dive into the etiology of your symptoms. She was gentle and extremely attentive when administering my ketamine infusions. I absolutely trust, respect and adore her!

Hayle Nguyen

Chip was amazing! She took the time to assess my skin and address my specific needs. I ended up getting Jeuveau, and I’m so pleased with the results! I’ll definitely be back! ❤️

Amy Jeanneret

I am so grateful with the educational knowledge and results I have gained through my journey with Chip and Vanessa. I have more energy, better sleep, and improved blood work results. I am motivated to stay focused on being healthy and making choices that benefit me for my well being. Chip is quick to respond and always provides a suggestion. They take time to truly understand the client and the communication and follow through is outstanding. Thankful!

Kartika Budiman

Chip was amazing at helping me understand my functional medicine labs. She took the time to explain what everything meant, connected the dots between my results and symptoms, and gave me clear next steps to improve my health. I finally feel like I have a better understanding of what’s going on in my body. Highly recommend!

Mary Nguyen

recently had a microneedling session at Chip's office, and she is an absolute master of her craft. She took the time to thoroughly assess my skin, explained every step of the process, and ensured I was completely comfortable throughout. The clinic is pristine, professional, and welcoming. My skin has never looked more radiant, smooth, and glowing. If you are looking for expert skincare treatments in a professional setting, I cannot recommend her enough!

I've been working with Dr. Chip and her functional medicine team since January and I am so thankful for them all! Dr. Chip and her team have helped me take my health seriously and create new healthy habits. She cares deeply about her patients and is very knowledge in all she does. Thank you Dr. Chip, you're the best!

I had such a great experience with Chip for microneedling! She was so professional, gentle, and made me feel completely comfortable throughout the entire process. My skin already feels so smooth and refreshed. I highly recommend her! ❤️

Chip really took the time to deep dive into my labs and look beyond just my symptoms to help uncover the root causes of my leg swelling, anxiety, and fatigue. I finally felt like someone was connecting the dots and looking at the whole picture. I also see her for aesthetics, and she is amazing with lasers! She has a very natural approach, and I always feel refreshed without looking overdone. Highly recommend Chip for both functional medicine and aesthetics!

Casey

Please describe how you felt prior to working with Chip and the Functional First Team. What prompted you to seek help?
My limbs felt heavy and I was worried about my heart health along with being pre-diabetic. I was also experiencing bloating, brain fog and fatigue. I was already trying the Keto diet and was not entirely sure what I was doing, so there was a concern about that. I had heard about functional doctors and wanted to give that a try.

All concerned areas have improved drastically. My heart health - blood panels have taken a 180-degree turn. My limbs no longer feel heavy. Gut health is improved...no more bloating. Much improved mental clarity and energy. My physical body feels looks and feels stronger. I just turned 64 and feel like I'm 35. It was great working with Chip and the team. Chip was able to pin point specific issues to address and provide the knowledge and action steps necessary to affect positive changes. Vanessa was a great help in answering my questions toward my new diet and offering solutions that worked. Brittany was a great help in keeping me motivated and helping to reduce my stress levels.

What wins did you experience due to working with Chip Nguyen and the team? Please be specific. How did Chip, Vanessa, or Brittany help you on your health journey? (symptom changes, mindset shifts, etc)
First thing was the capillary issue on my legs. After about just one month of supplements and better diet, the issue completely disappeared. Now, 8 months later, still perfect. Second was Chip figuring out that I might have H-Pylori. I had to take a daily pill to prevent heartburn. I'd been taking this medication of at least a couple of years. After 14 days of antibiotics, the H-Pylori was gone, heartburn gone, daily pill gone. Third thing was stomach issues. Stomach is much improved and still improving with the current group of supplements and better diet.

What wins did you experience due to working with Chip Nguyen & Vanessa Van Der Linden and the team? Please be specific. How did Chip, Vanessa, or Brittany help you on your health journey? (symptom changes, mindset shifts, etc)
wanted to share a few wins since working together. The most obvious one is sleep. My average sleep score is now around 85 on my Oura, which is kind of amazing for me. I still have nights where I don’t sleep great, but I also now occasionally sleep 8 hours, which honestly just never happened for years. Overall, sleep feels like a huge win. Even bigger than sleep, though, is my overall resilience. It feels really good to be in a place where we’re working to optimize instead of putting out fires. We’re improving things, and I have more goals and ideas I want to get ahead of, rather than constantly reacting to problems. That shift alone feels huge. For example, this month (since I’m not traveling), I set a goal of 10 CrossFit classes and 10 yoga classes, and I’m halfway through the month and on track. That’s on top of playing pickleball, golfing, and regular walking. I’m honestly thrilled to be able to manage this level of activity and feel good doing it. I also wanted to share some body composition data since I know you like objective measures. Over the past three months, my weight went up slightly from 143.5 to 145.5, but what feels more meaningful is that my muscle mass increased from 58.6 to 60 pounds, and my body fat percentage dipped slightly from 25.7% to 25.5%. I’m claiming this as a win—1.4 pounds of muscle at 58 years old! Who says you have to lose a percentage of muscle every year? This really feels like the result of the adjustments we’ve made together and the support from you, Chip, and Vanessa. I’m very grateful and excited to keep building from here.
