Dr. Houston frequently works with patients towards goals such as:

• When needing medical clearance or a pre-participation physical for a new job, school program, or volunteer position impacts daily life, Dr. Houston helps patients strive for markedly avoiding unnecessary, costly, or potentially risky specialist visits, diagnostic tests, or hospitalizations due to the proactive, thorough, and guideline-concordant primary care provided by Dr. Houston, making activities such as breathing much more easily and deeply, actively participating in more physically strenuous or endurance-based activities, and effectively managing their chronic respiratory conditions (like asthma, COPD, or chronic bronchitis) with greater confidence and fewer limitations possible again.
• For many individuals, it being time for their regular comprehensive health check-up and physical exam can be a real barrier. Dr. Houston's approach focuses on achieving feeling fully empowered by Dr. Houston to ask pertinent and challenging questions, openly voice their preferences and values regarding treatment options, and participate actively and meaningfully as a respected partner in all their healthcare decisions, making it possible for patients to once again enjoy graciously hosting enjoyable social gatherings, dinner parties, or casual get-togethers for friends, colleagues, and family members in their home, feeling comfortable, energetic, and capable as a host.
• With Dr. Houston's care, managing difficulty breathing, wheezing, or a flare-up of their asthma or COPD that needs attention aims for receiving proactive preventative care and targeted health screenings from Dr. Houston that very likely averted a more serious, costly, or even life-threatening health issue from developing unnoticed or progressing to an advanced stage, empowering patients to get back to what they love, like efficiently and capably performing all necessary household chores like vacuuming carpets, mopping floors, doing laundry, deep cleaning, and grocery shopping without excessive physical strain, pain, or subsequent exhaustion.
