The level of care and attention to detail that the Laguna Woods team displays is truly commendable. It is evident that they prioritize the well-being of their patients above all else, and their dedication to providing top-notch healthcare services does not go unnoticed. I would like to give a special shout-out to my provider, Talar, who has been nothing short of amazing. During my visits, Talar has consistently gone above and beyond to ensure that I feel heard, understood, and well taken care of. Her ability to listen attentively to my concerns and provide thorough assessments speaks volumes about her professionalism and commitment to patient care. I genuinely appreciate the time and effort that the Laguna Woods team puts into their work, and I am grateful for the positive impact they have had on my healthcare journey.

Many of them are stressed out, overworked, and suffering from burn out. It's these types of conditions that cause doctors to make mistakes and grow apathetic towards their patients, especially those in "factory" medical centers where the objective is to churn out as many appointments a day as possible. Dr. Frolov is none of those things. He is a genuine medical professional who takes the time to give his patients the attention they deserve. I have never, ever felt rushed during one of our appointments. He sits, listens intently, asks relevant questions, and makes a real, thorough attempt to get at the heart of whatever may be troubling you. He has a wide breadth of medical experience, but is not above pulling up recent medical articles from the web or referring you to a specialist if the situation warrants. His objective is to make you better. What I appreciate about Dr. Frolov, in addition to his expertise, are his bedside manners. He is polite and reassuring. This may not be as important to other people, but for me, the relationship between a patient and a doctor is a sacred one. My health is a very personal thing and when I bring my ailments, fears, and anxieties to my doctor, I want the comfort of knowing that there is someone very human, very personable on the other side of the table. Now, I don't want to delude anyone. Dr. Frolov keeps a pretty cool demeanor most of the time. I don't expect that he's going to wow anyone with his exuberance. He's there for a purpose, but he does it in a friendly way that makes you feel at ease. And in an industry where those basic niceties are getting harder to come by, I'm glad Dr. Frolov hasn't wavered. Lastly, because it needs to be said, Dr. Frolov keeps his appointments reasonably on time.

    Professional, experienced, intellectual, patient, and sincere. Dr. Frolov is a great doctor and…read morewonderful man.

    Excellent Primary Care Provider!…read more The entire team is friendly and efficient. Dr Chang is very knowledgeable regarding all health guidelines based on the latest evidence. He's very open and collaborates with his patients to achieve optimum health outcomes. He's also cognizant of insurance coverage challenges and advises what tests or procedures might result in out of pocket costs. I highly recommend Dr Change to all my friends and family.

My new employer charges an extra $50.00 a month for my insurance if I don't get a yearly physical, but their spin is I get a $50.00 discount every month for seeing a physician once a year. Within the last year, Dr. Chang has moved to a new location ( https://bit.ly/31vpBEP ) which is near the corner of La Paz and Moulton Parkway in Laguna Hills. The space is nice for a doctor office and it is reasonably close to my home. The reception desk ( https://bit.ly/2J7YCbU ) is just inside the entrance and waiting area has a decent amount of seating. Once you name is called, the first step is getting your vitals ( https://bit.ly/2qw3CRv ) taken before you are walked to examination room. First time I had an appointment with Dr. Chang was three years ago and most of his criticism had to do with me looking like a human version of the Stay Puft Marshmallow Man. I managed to put on a few more pounds before I became disgusted with myself and lost over 80 pounds in about 6 months. I went for a physical exam because I was having some digestive distress and I guess I was due for a visit because it had been several years between examinations. Dr. Chang did listen and conducted a thorough physical which included the thrilling prostate exam. The first time he did this exam I was like "Oh, my God!" He replied, "I am just putting on the glove." On my most recent visit during the exam I moaned another doctor's name. Don't do that! "Who is Dr. Jones?" "You're the only one!" Some time in the future I will upgrade to the endoscopic examination which is more commonly known as a colonoscopy. For those not familiar with the procedure, you are put into a twilight sleep while a long, flexible tube with a tiny camera on the tip is inserted into your rectum. The camera is guided through your entire colon which basically makes you star of your own Discovery Channel special (I hope they get my good side). If Jacque Cousteau was still alive, I would definitely want him doing the narration: "Slowly, we are going up Rohlin's colon. Up ahead a steak he had in 1988." On my latest visit, I received a fist bump for the weight loss, but Dr. Chang did mention some sun damage on my head and reminded me my shiny head isn't a solar collector. We briefly discussed my diet (which is atrocious), but since I don't smoke, rarely have caffeine or alcohol and not really a fan of narcotics, I am allowing myself a vice. The lungs sound really good and my vitals are excellent for someone in my age group. Rohlinism: If you don't enjoy your vices, you should find some new ones! The only thing I messed up during this latest visit was forgetting to fast which meant I couldn't get my blood drawn ( https://bit.ly/32Id9CQ ) until the following Friday. The technician who took my blood did it right the first time and the whole procedure was over in less than five minutes. I don't have large veins, so it can be annoying at times because technicians from time to time miss my vein. I like Dr. Chang and his staff which is a good thing since I will be seeing them at least once a year for the foreseeable future!
