What is Preston Arndt, MD?
Preston Arndt, MD is a physician practice at 411 West Ojai Avenue, Suite B, Ojai, CA 93023. The physician named is Preston Arndt, MD, and no other prescriber is listed. The practice offers seven services: Family Medicine, Men's Health, Early Dementia Screening, Nutritional Supplements, Personalized Medical Care, Bio-Identical Hormone Therapy, and Integrated & Functional Medicine. Most of that list reads as primary care, with hormone therapy among a few added focus areas.
In its own words, the hormone service is "Careful evaluation and individualized treatment for patients experiencing symptoms associated with hormonal changes." The practice does not name the medications it uses or describe the treatment beyond that.
Google reviewers give the practice 4.8 from 57 reviews. The practice is also building a new website with more information about its approach, due to launch October 1, 2026, so details may change after that date.
What does it cost?
It does not publish prices. It does not say whether insurance is accepted, and it does not mention a consultation fee, membership plan, HSA or financing. Ask about each of these before you book.
What should you ask before you book?
Ask whether Dr. Arndt will be the one prescribing, and who handles your care when he is away. Ask whether the practice takes insurance at all, and what a visit, follow-up and lab work cost out of pocket. If hormone therapy is what you need, ask which medications are used, whether they are brand-name or compounded, and what a monthly fee covers if there is one.
The practice does not name weight loss, peptide or longevity programs, so ask directly if you came for one of those. Also ask whether telehealth is offered, what the office hours are, and how to cancel or stop care. The practice lists three phone numbers, 805-233-4231, 805-273-0216 and 559.335.8408, so ask which one reaches the front desk.
Who is it a good fit for?
This is a good fit if you want a physician for general care or one of the listed concerns, such as men's health, hormone symptoms, memory screening or supplement guidance, and you are willing to call and get prices and terms before booking. It is less clear a fit if you came specifically for a weight loss, peptide or longevity program, since none is named.
