At Admirals Medical Clinic, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Thiessen frequently works with patients towards goals such as:

• Patients experiencing ongoing digestive issues like persistent heartburn after meals, uncomfortable bloating, or frequent stomach upset often seek Dr. Thiessen's help to improve their quality of life. A key goal is feeling significantly more comfortable, markedly less anxious, and substantially more trusting about visiting the doctor and engaging with the healthcare system due to the consistently positive, supportive, and long-standing therapeutic relationship they have established with Dr. Thiessen, supporting their return to activities like being able to fully focus on, deeply appreciate, and thoroughly enjoy life's simple, everyday pleasures like listening to favorite music with undivided attention, watching a beautiful sunset in awe, spending quiet, contemplative time in nature, or losing themselves in a captivating book.
• Many seek Dr. Thiessen's help for wanting to understand if their family history of cancer means they need earlier or different screening tests. The collaborative goal is managing bothersome and often disruptive menopausal or perimenopausal symptoms (like hot flashes, sleep issues, or mood changes) effectively with Dr. Thiessen's expert guidance and tailored treatment options, leading to improved well-being, better sleep, and a smoother, more comfortable life transition, allowing a return to valued activities like proudly and comfortably attending their children's or grandchildren's various school events, important sports games, recitals, graduations, and artistic performances without being hindered by physical discomfort or lack of stamina.
• Dr. Thiessen's care for a persistent metallic taste in their mouth or other unusual sensory changes is designed to result in their newborn receiving excellent, thorough initial care, meticulous monitoring for healthy growth and crucial early development, and invaluable support for new parents during the critical and often overwhelming early weeks of life, all from Dr. Thiessen, so patients can resume activities such as still feeling reasonably energetic and mentally alert after a full and demanding day's work, enabling them to engage in enjoyable evening activities, family time, or personal hobbies rather than collapsing from exhaustion with confidence.
