If you already know what you have he is good doctor to go to but if you don't he just refers you to someone else.

It's always a pleasure to interact with his efficient, friendly and caring secretary/office manager, Michelle! Dr Ammie Kahl is an equally FANTASTIC addition to the Practice!

This review is for the medical practice rather than Dr. Tenenbaum himself…read more I've been a patient of Dr. Tenenbaum (technically one of his physician's assistants...you know the deal) for about 3 years. My medical history is pretty normal, so there isn't much to cover here: go in, get blood work done, get reminded that I have such-and-such value that is slightly above the norm for the population. Rinse, repeat. What drove me away from this practice (other than the 2020 pandemic...) is that Dr. Tenenbaum transitioned his practice to...concierge medicine. This artificially reduces the number of available physicians in the area, ultimately driving up medical costs for patients who do not necessarily need 24/7 support. I cannot ethically support this business practice, despite having the privilege of being able to pay an extra $200/mo for a service that I will likely not benefit significantly from...at least in the short term. I request that physicians reconsider going 100% concierge and consider a hybrid practice model. Allow those who cannot afford concierge medicine the ability to unlock a variety of physicians in the area. Healthcare is challenging enough as it is in this country...please don't add to the problem.

My mother's prescription records show that she was prescribed (among various other monthly meds) 180 Percocet tablets as a 30-day supply, with each tablet containing 325 mg of acetaminophen (Tylenol). Her death certificate ultimately listed acetaminophen/Tylenol overdose as her cause of death. I also personally had serious concerns about the way her medications were managed. Her appointments with Dr. Darden were often conducted over Zoom and, in my experience, very little time was spent with her before refills and/or new prescriptions were issued. After her death and reviewing her medications more closely, I was deeply disturbed by what I learned and have serious questions about the prescribing and monitoring of her medications. I am not claiming to make a medical or legal determination about who was responsible for her death. I am sharing the documented facts surrounding my mother's prescriptions, what I personally observed regarding her appointments, and the concerns our family has as a result. I strongly encourage patients and their families to be proactive: understand every medication being prescribed, know what ingredients are in them, ask about interactions and cumulative dosages, and seek a second opinion if something does not feel right. I wish more than anything that I had known then what I know now.

Last October, I helped my parents move to California. They were quite nervous about starting over…read moreagain, so to speak, and meeting new doctors was an unsettling thought. However, I knew that Dr. Feldman would be just the right fit for both of them because I too had already experienced her wonderful care. When joining her practice years ago, my husband and I were surprised to find that Dr. Feldman adopted the same work ethic we remembered from childhood--the days when our GP would phone us at home to check up on us. She cared about the root of the problem and investigating our symptoms until she could suggest the correct course of action. For this reason, I knew that she could help my parents--especially my father whom I felt was on a downward spiral as a result of bad medical advice. She took on the challenge immediately, and within two days of treatment my dad began to improve. Apart from recommending her own course of treatment for various health issues, she knew exactly which doctors would be good for my dad. She referred him to the best, and made sure that he was seen in a timely manner. There is no such thing as a disappointing visit at Dr. Feldman's office; her willingness to listen and solve problems is refreshing in a field where one hardly gets more than three minutes with a doctor per visit. The team in her office is spectacular; Ariel and Claudia always answer the phone; rarely is there a need to leave a message, but if we do--their response is instant. They are friendly, and always willing to help. Joining this practice gives my parents and I peace of mind that they are receiving the best possible care. There is no one like Dr. Feldman.

She listens to my concerns and addresses them, not always with a pill until that becomes necessary. She has referred me to an acupuncturist and a chiropractor to aide in my health, more long term treatment but I appreciate that approach. Unrushed and thorough, she is very upfront in a kind and understanding way. Her staff is fabulous as well. When she became a 'concierge' doctor with MDVIP, I couldn't find another doctor I liked so I forked over the $$$ per year to see her again. I will continue to be a patient as long as I am able.

My husband and I have been patients of Dr Gerayli since she came to Camarillo and we are very happy…read morewith the care we have received from her and her staff. Over the years, my weight crept up to 200 pounds. In March of 2022, Dr. Gerayli suggested that I try Ozempic as a way to curb my appetite. I agreed and she gave me some guidelines for planning my food intake: eat only during an 8-hour period; limit breakfast, lunch and a snack to about 200 calories each and dinner to about 600 calories; exercise regularly. Monthly visits with Dr. Gerayli kept me on track. By taking the Ozempic and following her suggestions, I lost 50 pounds over a nine-month period. My husband and I are very grateful for the helpful advice and counselling Dr. Gerayli provided. My size has dropped from 20 to 12. I am very happy with the way I look and my increased mobility.

She was so tacky and assumptive it was difficult to even maintain a cordial relationship. She requested I go through 4 different appointments before prescribing a very common rx that I ve been taking for over 20 years and will take for life. The woman at the end of the front desk was condescending. There seems to be theme in that office. I have zero confidence in them to the point I immediately switched Primary's after the appointment. Awful.

I had seen countless doctors that either dismissed my condition or treated it with something that made me feel worse. I knew that something was being missed and I'm glad I didn't give up because when I met Dr. DeSylvia she finally helped me get the answers and treatments I was seeking. I am writing this review today because she has changed my life through her 360 degree medical approach. From the increase in my energy, a well balanced life and to my pain relief, this Dr. made sure to listen to my individual situation and make medical recommendations that were unique and specific to what I needed. She gives you her full attention and draws from a wide body of medical knowledge in order to support your success in living a healthier lifestyle. If you are are looking for someone who will really listen and help you get to the bottom of what's making you sick, I recommend you see Dr. DeSylvia and her team. Thank you Dr.!

He did not try to look at me for 10 minutes and rush me out the door like all my doctors have done. I haven't had any medical insurance for a long time and at 50 years old and somehealth issues I'm way overdue for a checkup. He saw me late (a 6 p.m. appointment).
