    You could not find a kinder, more compassionate, more responsive doctor than Dr. Buyalos (or "Dr…read more B." as we called him.) I knew when I first consulted him that I had to move on to DE IVF and that I wanted to transfer only ONE embryo when the time came (due to a fibroid which I'd been told would cause crowding and due to seeing how high risk twin pregnancies are from friends who'd had twins.). Unlike another doctor at the same clinic (who's no longer there) who told me, "Oh no. We couldn't transfer only one embryo because that might lower our success rates!" Dr. B. told me he agreed with my decision and would abide by it. Then during an attempt at doing DE IVF he screened our donor in person and called me with his impressions before and during her cycle, making himself accessible in ways no other RE had ever done. He also had a donor cycle coordinator at that time named Arlene who was AMAZING. (I'm sad that she no longer works at his clinic but hope the new coordinator is as great as Arlene was.) Dr. B. is that RARITY in fertility medicine---a kind, compassionate, HONEST, hardworking and ACCESSIBLE doctor! Without him, our daughter would not exist and she is the light of our lives. Thank you Dr. B!!!!

    I highly recommend Dr. Rick Buyalos and his team. Compared to other physicians I consulted, he…read moredemonstrated exceptional expertise in interpreting hormonal changes and follicle development, and consistently made thoughtful, individualized decisions based on my lab work. Beyond his clinical skill, Dr. Buyalos showed genuine compassion and integrity. He supported me with patience and honesty, which helped rebuild my confidence despite my age. During financial difficulty, he even worked to reduce fees so I could continue treatment--something I deeply appreciated. Although I did not achieve the outcome I had hoped for, his guidance--especially our conversations about considering donor eggs--has stayed with me. Looking back, I recognize there were times I struggled to accept that reality, but he remained supportive throughout the entire process. I'm grateful for his care and professionalism, and for the way he treated me as a person, not just a patient.

    My (adult onset T1 diabetic for eleven years) boyfriend has been a patient of Dr. Thorsell's team…read morefor years, and we have previously been to a number of other endocrinologists in SLO, SF, NYC, and OC. None have been half as competent or caring. Her staff is friendly, helpful, and timely. We've never waited more than 15 minutes to be seen. Refills are faxed promptly to our pharmacy. We are treated with respect, which is unusual in the healthcare realm (what? your patient isn't an absolute moron?!?). They've done more for his diabetes management than any other endo, and on top of that, they can personally relate to type 1 diabetes, which helps immensely. Despite the fact that I love being able to reach them and get stuff dealt with quickly, and I don't want her to become another overbooked SLO doctor's office, I recommend Dr. Thorsell to everyone I meet who needs an endocrinologist.

    Dr. Ashley Thorsell is dangerously bad at caring for type 1 diabetics!…read more At my appointment she was condescending and rude! She kept insisting that I do things her way. (Even though I told her multiple times that I had already tried her suggestions and they didn't work for me because they negatively affected my health!) Living with type 1 diabetes for 28 years, I'm not exactly an amateur at managing a diabetic lifestyle and would appreciate not being treated like one. Then to add insult to injury, she kept insisting that I follow her "meal plan". When I told her that I don't have time to do that, even though I made an effort to, she made a comment that she has a 1 year old at home and still has time to eat with that meal plan! (Her "meal plan" causes my blood sugar levels to be low for most of the day which is problematic because I have 2 young kids at home. I don't have time for my blood sugar levels to be constantly low!) Stubborn behavior like that just proves how little she listens to her patients! Because, I told her multiple times that I'm a stay at home mom! I'm "glad" she has the time to eat her "meal plan" during a paid lunch break while she's at work and her child is being cared for by somebody other than their own mother (actually that may be a good thing for the child) but that routine doesn't work for me. Being a doctor she should be a little more open to the possibility that other people live different lifestyles than her own if she wants to succeed. Her office staff isn't any better either! (Maybe there is something in the office water?) For the entire time that I was a patient of Dr. Ashley Thorsell, they showed the upmost incompetence. Never once managing to be capable of a task as simple as handling my diabetes supply order. The diabetes supply company even tried to get them to cooperate multiple times. The inability of the entire office to perform their jobs correctly ultimately led to having to switch endocrinologists. I highly suggest ALL of her type 1 diabetic patients do the same! Word of advise for those considering Dr. Ashley Thorsell as your possible endocrinologist... JUST DON'T!

    I took my son to this endocrinologist as he was the only one in the area that I was aware of that…read moreis pediatric. My son had been gaining weight rapidly for no reason and nothing has changed in his diet or lifestyle. When I saw the Dr and brought my lab work showing high insulin the Dr seemed un interested and said my son could go to a "fat camp" where kids exercise. Now I'm not an over weight person myself and I don't get offended by people suggesting a person lose weight but my son was 11 and gaining for no reason we could discern and rapidly. This comment to me suggested he was a lazy Dr who didn't think it was an issue for an 11 year old male child to have insulin levels 3 times the norm and not at all want to explore further as to WHY? Long story short I went to UCLA hospital and it turns out my son had a serious medical condition and endocrine issue. How the heck does this Dr have glowing reviews? He didn't even want to explore further. Medicine is called practicing medicine for a reason. You practice it and you explore why a patient is presenting with HIGH insulin as a child. You don't tell a parent to take the kid to fat camp. It wasn't diabetes and even if it was the fact that he didn't want to even draw blood work to see is shocking. Now years later I'm sharing my review because I think Santa Clarita deserves better and so do kids.

    Dr. Hasan is excellent! I highly recommend him as he is patient, genuine & knowledgeable…read more Stephanie, is wonderful too! She is very professional, warm & friendly. I had the best experience seeing them this year. They are a great example of how a Doctors office should be.
