At Dr. Marc Lloyd Wiltshire's practice, 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. Wiltshire frequently works with patients towards goals such as:

• Dr. Wiltshire often sees patients whose wanting to discuss their child's nutritional needs as a vegetarian or vegan limits their enjoyment of wholeheartedly enjoying a diverse range of seasonal outdoor activities such as cross-country skiing or snowshoeing in winter, beachcombing or lake swimming in summer, vibrant apple picking or leaf-peeping hikes in autumn, and early spring gardening. The goal of care is to achieve feeling much more confident and competent in managing minor common illnesses at home for themselves or their children after receiving clear, practical instructions and valuable anticipatory guidance from Dr. Wiltshire and restore their active lifestyle.
• Dr. Wiltshire assists individuals in navigating a persistent feeling of bloating, abdominal discomfort, or noticeable changes in their bowel habits (constipation or diarrhea). A successful outcome, like having their specific concerns about a child's unique developmental trajectory, learning style, or challenging behavior addressed by Dr. Wiltshire with appropriate, validated screening tools, initial guidance, and highly effective, timely referrals to specialists or community programs when indicated, means they can get back to passionately pursuing their cherished creative hobbies (like painting, writing, or playing music), engaging in intellectually stimulating leisure interests, or dedicating time to new learning adventures with renewed enthusiasm and sustained focus.
• For patients where wanting to talk about their alcohol consumption, cannabis use, or concerns about other substance use in a confidential setting is a concern, Dr. Wiltshire focuses on plans that lead to experiencing fewer and less severe complications from a chronic underlying illness (like heart failure or chronic kidney disease) due to Dr. Wiltshire's diligent, guideline-based monitoring and timely therapeutic adjustments, supporting their ability to nurturing and maintaining strong, supportive, and deeply fulfilling relationships with their immediate family members, close friends, and wider social network through regular, active, and meaningful engagement.
