I've been coming to Nancy for years and have recommended so many friends and clients to her. She has a gift unlike others and that typical drs are not able to tap into. Expensive but worth it as she's the only one I see read more

I have personally sent no fewer than 50 people to Nancy Sacks with rave reviews from every one. Not only has she been an incredible asset for my own health and healing, but has helped countless people I personally know. Whenever a family member or close friend has a health issue, in my top 3 recommendations is paying a visit to Nancy Sacks. I have sent business associates, friends, and pretty much everyone I care about who is local to LA... and again, RAVE reviews from everyone! I simply cannot recommend her services any higher. However, one caveat... she is not a miracle worker, you must absolutely do things from your own side and put in the time and dedication if you want to see incredible results. In other words, if she tells you to do something, follow her instructions to the T. You will be happy you did. That's been my experience. I hope this helps! read more

After experiencing several debilitating migraines within a few month period, I scheduled an appointment with Nancy Sacks based on a referral. After one QXCI session, Nancy was able to assess what was causing my headaches and suggested some homeopathic remedies. I followed her advice and have not had a migraine since. I now see her regularly and am so grateful for her help! read more

Holistic Haven is a rare gem in Westlake Village! You immediately feel welcomed and relaxed by the soothing sounds when you enter the office. The staff is impeccable and is always courteous and extremely helpful. I have been seeing Nancy for years as well as my whole family. I can honestly say that we have put our trust in her guidance and wisdom. My entire family is healthier and happier because of it. I rarely write reviews because in this day and age it is difficult to find such high quality care and service. I whole heartedly recommend her to anyone who is searching to improve their health and well-being. read more

Nancy Sacks is such a God send!!! My first session with her back in 2014 was LIFE CHANGING! She addressed my concerns with compassion and expertise, considering my whole situation. She counseled me to make important changes that have truly turned around my health for wellness! I feel the equipment, testing she does produce results that far outweigh the information I get from traditional medicine. I refer everyone I know who has a mysterious medical issue to go see her and she points the way to better health. Her staff is super friendly and the office is cozy and comfortable. Thank you Nancy for all you do to help others!! read more

This is what I love: Nancy gets to the cause; she doesn't just treat the symptoms. After unnecessary knee surgery (that didn't stop leg pan) and persisted for two years, Nancy figured out the cause and on the 8th day after starting treatment, I was 80% better. That was several years ago, I'm at 100% and the problem has not returned. Now, she's helping with GERD (acid reflex) and getting me off prescription medication I've been taking for years. I now understand that the pharmaceutical killed the acid and treated the symptom of heartburn, but had digestive consequences that made me quite ill. I'm following her plan and making a wonderful recovery; I feel great for the first time in a long time. If I'd gone to my 'regular' doctor, I'd have gotten another pharmaceutical to treat the symptoms and never would have gotten to the cause and to the cure. Give her an hour and she'll tell you more about your body than you knew was in there. (And it doesn't hurt that her name is Nancy.) read more

Just saw dr Nancy Saks for the first time, mind blowing all of this. First thing she picked up was the parasite I got from eating fish two months prior. I didn't even tell her I was doing colonics elsewhere, she also saw that my adrenals where really out of balanced. Gave me sone natural supplements and it has changed me for the better beyond what I could of imagined !! I will continue to see her every four weeks to makes sure ever thing is still working. Love her read more

I am so grateful to have been introduced to Dr. Nancy Sacks. I was immediately attracted to her approach and her sincere kindness, generosity, patience, and ability to truly listen. It brought me new hope for my healing process. What sets her apart is her sensitivity to her patients' needs. I recently moved out of town and although I have been in touch with her over email, I know I won't be able to find anybody like her here. I found a doctor that I can trust, both as an expert in her field, but also as someone I can confide in. I highly recommend her and visiting the Holistic Haven! read more

Dr. Nancy is a miracle worker. I have been a loyal patient of hers for many years for various anxiety related alignments. Dr. Nancy has treated me with her homeopathic remedy recommendations without any negative side effects of traditional medicine. Highly recommend Quiet Calm for those restless nights in bed. read more

Nancy is a profound listener. She listens to your words, your body, and your energy. I know, I know, I sound like I'm drinking the Koolaid too deeply, but I'll tell you this much. I came to Nancy stressed to the max and exhausted. Two weeks later I'm refreshed, recharged, and euphoric. Whatever and however Nancy makes her magic happen....sign me up for MORE :-)!!! read more

Nancy Sacks is a miracle worker! I have been to many, many, "doctors" over a 20 year period trying to get to the root cause of my ill health. I've followed their protocols religiously and spent thousands of dollars in vain. I am the healthiest sick person on earth. I don't drink, smoke, eat only organic and have an extremely healthy diet. Yet I remained sick. Nancy is the ONLY person who's been able to figure out what was going on with me. ALL of my symptoms are gone and I've never felt better. I'm finally healthy. Nancy gets to the root cause and doesn't just mask symptoms. She is kind, gentle, knowledgeable, informative, and intuitive. She has no ego and designs an effective regime that will work with your lifestyle. Yes, she will send you away with some supplements, but she won't overload you. She is very respectful of your budget and understands that it's not cheap being sick. Her services aren't free, but they're a bargain for her knowledge and expertise. She's certainly not out to gauge you because she thinks she's God like most doctors. She's just asking a fair wage for her time and knowledge. She will actually make you well if you follow her advice so you'll no longer be beholden to the pharmaceutical industry. She has also helped my children and husband regain their health. We've all had different issues and she has masterfully alleviated all of them. Real health and happiness is now ours thanks to Nancy Sacks. She is a Godsend and well worth the hour drive we make to see her. Save yourself time, money and frustration by going to Nancy and following her advice. You'll never look back. read more

It all started 20 years ago when Nancy helped my 2 year old get off a year of antibiotics for various health issues. During the last 20 years she has helped my entire family thru many mild and serious health issues. I have been seeing Nancy religiously every 6 weeks for wellness care. She treats the whole person...mind, body and spirit. She is our first go to option. I have recommended her to many friends. The bottom line is Nancy has integrity, love and compassion! All the qualities that are essential from a healthcare provider. I love her peaceful office space and amazing people she has working there. Don't know what I would do without her! read more

I feel very comfortable talking with Nancy. Whenever I go to Thousand Oaks I try to schedule an appointment with her. I love the neurofeedback, as well as the herbs and minerals she recommends. I prefer this model of healthcare. I do not have insurance. I also do not believe it's a doctor's responsibility to "cure"...but an agreement that the patient makes with herself to improve her own health incrementally. That means lots of work from my side! Dr. Sacks supports that. If you are on the TO side of LA County, definitely check her out. read more

Dr. Sacks is talented, but, this practice is overpriced. The secretary is not very bright and charged me for an appointment that I cancelled and rescheduled for a later date. Ethically, I can't continue going here. read more

I cannot say enough positive things about Nancy Sacks, Holistic Haven, and the extraordinary benefits I personally experienced from her therapies. She has helped me address long-standing health issues that were preventing me from experiencing amazing health in just one session! The staff is super friendly, her store is filled with awesome products, and Nancy herself is down to earth, approachable, extremely knowledgeable, and very kind. I have sent over 40 people I know to Nancy because I trust her capabilities and technologies to recognize the problem and remove it. Thank you Holistic Have for all you have done for me and my health! read more

Nancy was dismissive when I inquired about help for my daughter. She never called. Emailed that she was booked for 4 months and directed me to contact her assistant. All when I was seeking help for a 12 year old child! No referrals, no investment of time, energy or commitment . If there was a negative rating I would give it. It seems she is only interested in adults that need a good listener. Not the real deal. read more
