What is Simi Obstetrics & Gynecology Medical Group?
Simi Obstetrics & Gynecology Medical Group is mainly an obstetrics and gynecology practice at 1147 Red Tail Way, Simi Valley, CA 93065. The phone number is (805) 527-8055. The practice says it serves the Greater Los Angeles area and Southern Ventura County. Its team is Catherine Kim, M.D., Grace Lee, M.D., Irene Tan, M.D., and Brittney Ayers, FNP. Dr. Kim has been in practice in Simi Valley since 1998. The office is open 8:30 am to 5:30 pm Monday through Thursday, 8:00 am to 4:30 pm on Friday, and closed on weekends. It has a Google rating of 3.8 from 13 reviews.
The practice lists six services: pregnancy, ovarian cysts, endometriosis, hormone therapy, uterine fibroids, and contraception. Hormone therapy is one of those six. In its own words: "We also offer bioidentical hormone treatments and therapies that can provide relief for hormonal problems experienced by women of varying ages." It does not say which hormone treatments it offers or which clinician provides them. It lists no weight loss, peptide, or longevity services.
What does it cost?
It does not publish prices or a consultation fee. It does not say whether it accepts insurance, and it does not describe cash pay, HSA use, financing, or membership plans. Its contact information says to call the office to book, so that is the simplest way to get answers. Ask for the cost of a first visit and of a hormone therapy visit, and whether either one includes the medication.
What should you ask before you book?
Ask which clinician handles hormone therapy and who writes the prescription. Ask whether the practice accepts your insurance, and if it does not, what a visit costs in cash. Ask whether the hormone medication is brand-name or compounded, and whether its cost is part of any fee you pay. Ask what follow-up visits and lab work cost, and whether telehealth is available, since it is not stated. Finally, ask how you would stop care and whether there is a charge for doing so.
Who is it a good fit for?
This is a good fit if you want hormone therapy from a practice that also provides gynecologic and pregnancy care, and you are comfortable calling ahead to get prices and answers before booking. It is not a fit if you are looking for weight loss, peptide, or longevity care, since the practice does not list those services.
