What is Nikola Lozanov MD?
Nikola Lozanov MD is a family medicine practice at 108 Lynch Creek Way, Suite 4, in Petaluma, CA 94954. The phone number is (707) 782-1244. Dr. Nikola Lozanov runs the practice and is the physician named as its prescriber. The practice has served Petaluma and surrounding areas since 2006 and welcomes patients three years old and older. Its Google listing shows a rating of 3.3 from 16 reviews.
Dr. Lozanov holds an MD, is fully trained and certified in functional medicine, and is a Certified Medical Examiner with the US Department of Transportation, which covers the DMV examinations. Dr. Rita Melkonian, who practices gynecology and urogynecology, comes to the office on Thursday mornings. Her office uses the same phone number.
Services include primary care, which covers well visits, treatment of injuries and illnesses, chronic conditions, and nutritional guidance and weight loss care. The practice also offers bioidentical hormone replacement therapy, EKG, laser pain therapy from Multi Radiance Medical, knee and shoulder cortisone injections, cryotherapy, hemoglobin A1C testing, and several lab tests. Hours are Monday through Thursday, 9:00 am to 5:00 pm, and Friday, 9:00 am to 1:00 pm, with a lunch closure from 12:30 to 1:30 pm.
On hormone therapy, the practice puts it this way. In its own words: "BHRT comes in several different forms, and at Nikola Lozanov MD, we carefully take into consideration your symptoms, medical conditions, and history before making a recommendation for a specific treatment."
What does it cost?
It does not publish a price or consultation fee for hormone therapy. It does not say whether any hormone medication is included, or whether visits are billed to insurance.
Published prices are for testing. The Spectracell micro-nutrient panel is $190 with insurance or $290 without. The US Biotek food sensitivity test is $268. The DUTCH hormone test is $300 per kit, picked up at the office, and insurance does not cover it. No prices are listed for office visits, laser therapy, or injections.
What should you ask before you book?
Ask who writes the hormone prescription. The practice does not say whether Dr. Melkonian prescribes hormone therapy, so ask directly. Ask what the first visit costs and whether that fee includes any medication. Ask whether the medication is brand-name or compounded, and which pharmacy fills it. The menu lists an Online Pharmacy, but the practice does not say what it carries or whether prescriptions are sent there.
Ask what follow-up lab work costs, and how often a $300 DUTCH kit would need repeating. Ask whether weight loss care includes a prescription, since none is named. Ask whether video visits are offered, which the practice does not say. If there is a membership or package, ask how cancellation works, since no terms are described.
Who is it a good fit for?
This is a good fit if you want in-person family medicine in Petaluma, with hormone therapy, testing, and procedures under one roof, and you are willing to get prices and prescribing details before you book. It is a harder fit if you need a posted monthly price for hormone care or video visits, since neither is stated.
