What are people saying about Dr. Lundquist?

Won’t go anywhere else in town and thrilled to have an amazing & competent team here in TEMECULA so I don’t have to drive to San Diego anymore! The best holistic approach with a staff of so many different doctors & treatments. You will not be disappointed in the true care you get here where they actually work to find the root cause vs throw drugs at every symptom you have. Really want to get well & healthy??? Then this is the place to go!

Tamara Bienvenue

Dr. Lundquist is an amazing physician. It’s great to see more doctors like him practicing functional medicine. It took me nine doctors and a year and half until I could find one who could finally help me. I drive an hour each way to see him and it’s well worth it. Thank you Dr. Lundquist!

Ashleigh Armstrong Chapman

If you’re looking for a doctor who can think past medical dogma, who looks for root cause, who really listens to you and is willing to consider your ideas, who takes time to make a thoughtful diagnosis and is always respectful then this is where you want to be. I fired 8 doctors before I found Dr. Narayan and Dr. Lundquist. So glad I didn’t give up searching for doctors who are well trained and always learning more to better their practice. Thank you!

Finally a doctor that actually LOOKS and LISTENS to you while talking to them. I have celiac and was wanting to get rid of all the junk in my gut. He is the only doctor that suggested I do this. He is the only doctor that will have classes and actually invite his patients to attend. My wife and I love all of the staff their. Thank you Dr. Lundquist.

Ruben Flores

Dr. Lundquist is an amazing person and a phenomenal doctor. He believes in treating his patients as a whole, and not just by their diagnosis. He takes the time to really get to know his patients before he decides on treatments, unlike other doctors who talk to you for 5 minutes and dish out pills. He has completly changed my life and I will forever be grateful! I am blessed to be part of his amazing team at his new clinic! Thank you Dr. L!!!

Melissa Reilly

Love Dr Alisha and Dr Lundquist They are updated with all the newest research on natural medicine. Not just pop a pill and go home. This is the future of medicine. Thank you Doctors for genuinely caring about your patients.

I of course would never give up Dr. Hazen my amazing chiropractor and Ann, my incredible massage therapist. But now that they are here, I am so excited to get into Dr. Lunquist for my thyroid and hormone issues I have been having. This is a one stop health center that I am very excited about.

Dr. Lundquist and his team of amazing practitioners

Love Dr. Lundquist! After being undertreated or treated with inferior medications for my thyroid for 13 years, I started doing some research on proper thyroid treatment and doctors who bother to learn such treatments, and I was lucky enough to find Dr. Lundquist. He listens, considers more than just labs (he actually takes symptoms into account), and is open to learning from his patients as well as educating them. His testing was thorough, and he didn’t just throw a bunch of prescriptions my way, which I appreciated. It’s not easy to find doctors who aren’t intimidated or annoyed by patients who do their research and advocate for themselves, but Dr. Lundquist welcomed it. It breaks my heart that I’ve had to move across the country and won’t have him as my doctor anymore. I highly recommend him for any health issue you may have!

Farra Wicks

Dr. Lundquist has always taken excellent care of me. I would always recommend him to my friends and family!


Mathew Brady

I so enjoy Dr. Erik Lundquist teachings and how he really cares for his patients. He is turning off my autoimmunity after struggling for over 17 years. It’s a process and I finally have hope for a better life. Thank you Dr. L.

Debbie Bartlett

I was a walking talking hot flash until I saw Dr. Lundquist. That was over 2 years ago and I haven’t had a hot flash since then! He really takes the time to listen to you and come up with a game plan that really works.

Debbie Halzle Valenzuela

Absolutely love dr lundquist and dr Hazen! I have a lot of health issues but feel confident they can help and already have! They really care and spend time with you.. Amazing peeps!

Debbie Hendrickson

After 40 years of misdiagnosis and mistreatment by the medical professionals in four states, I finally found Dr. Lundquist and feel better than I did in the previous 40 years.

Dot Hoffman

I am so grateful for Dr. Lundquist and his willingness to learn and practice medicine without following dogmatic practices. I am even more grateful he lives up to the name doctor (which means “to teach” in Latin) and passes on his knowledge to patients.

Kristin Herbert

“Dr. Lundquist always takes the time to listen, ask questions and offer treatment that is right for me. I never once felt like he was judging or questioning me and when I was struggling the most, his caring and compassion made him feel like more than just a doctor. I trust Dr. Lundquist completely. I hope I never have another primary care doctor besides him. Ever.”

“Had the BEST visit with Dr Lundquist! He listened to me and took the time to make sure I understood everything. I’ve been battling Hashimoto’s for YEARS and I finally feel like someone understands it!!!”

“I have never had a doctor like Dr. Lundquist. His patience, understanding and compassion are unbelievable. He has treated me through two major back surgeries in the last three years and I honestly don’t know what I would have done without him. I never once felt rushed when I was with him.”
