Dr. Lewis works closely with each patient to identify the cause of their allergic symptoms and develop personalized treatment plans — including allergy testing, symptom management, and immunotherapy — to reduce or eliminate allergic reactions over time.

  • Cold-like symptoms that persist for several weeks
  • Difficulty breathing or wheezing
  • Frequent skin rashes, hives, or itchy skin

About Our Cardiology Services

Cardiology is the branch of medicine focused on diagnosing, treating, and preventing diseases of the heart and blood vessels. At Olean Medical Group, our cardiology team uses advanced diagnostic tools and treatment strategies to support heart health and manage chronic cardiovascular conditions.

Whether you’re managing high blood pressure, recovering from a cardiac event, or monitoring symptoms like chest discomfort or shortness of breath, our experienced heart doctors are here to help. We care for adult patients (ages 18 and up) and collaborate closely with primary care providers to ensure continuity of care.

When to See a Cardiologist

Heart disease remains the leading cause of death worldwide — but early detection and prevention can make a life-saving difference. Here are some key signs and risk factors that may indicate it’s time to consult a heart specialist:

  • Chest Pain or Pressure If you experience chest pain, especially during physical activity, it could be a warning sign that your heart isn't receiving enough oxygen. Severe or sudden chest pain may be a sign of a heart attack — call 911 immediately.
  • High Blood Pressure Chronic hypertension makes your heart work harder and increases your risk of stroke and heart disease. A cardiologist can help monitor and manage your blood pressure effectively.
  • Diabetes Having diabetes significantly increases your risk of heart disease. Poor blood sugar control affects blood vessel health, circulation, and cholesterol levels.
  • High Cholesterol Excess cholesterol can build up in your arteries, restricting blood flow and raising your risk of a heart attack. Our Lipid Clinic helps patients manage cholesterol with diet, lifestyle changes, and medication when needed.
  • Shortness of Breath, Dizziness, or Palpitations Unexplained shortness of breath, irregular heartbeats, or frequent dizziness may signal an underlying heart condition and should be evaluated promptly.
Schedule an Appointment

If you're experiencing any of the symptoms listed above or have concerns about your heart health, don’t wait. Our cardiology team is here to help you take proactive steps toward a healthier heart.

Neurosurgery*

Neurosurgery at Olean Medical Group

Neurosurgery is a specialized field of medicine focused on the prevention, diagnosis, surgical treatment, and rehabilitation of conditions affecting the nervous system.

At Olean Medical Group, we make specialized neurosurgical care more accessible by partnering with visiting neurosurgeons who see patients on-site each month. Your primary care provider or specialist will help determine if a neurosurgical evaluation is right for you.

Our nursing staff will help guide you through the process — from scheduling and medical record coordination to follow-up instructions.

When to See a Neurosurgeon

Neurosurgeons typically see patients by referral. If you’re experiencing symptoms like chronic back pain, nerve compression, sudden weakness, or neurological trauma, your primary care provider or neurologist may recommend a surgical consultation.

Take the Next Step

If you're concerned about a neurological issue that may require surgery, start by speaking with your primary care provider. They’ll determine whether a referral to one of our visiting neurosurgeons is appropriate.
